Komachi/Cure Mint in Yes! Pretty Cure 5. In theory, somewhat limited in usage compared to other forcefielders, since she can only produce Mint Protection and Mint Shield around herself rather than just anywhere. In practice, they're strong enough to make Mint the team Worf, can provide pathways for her teammates' powers, and have no apparent limit on range, and the Mint Shield in particular does damage on contact and has been used as a massive Kamehame Hadoken. In season two, though, she loses these abilities, which are replaced with the more traditional attack Emerald Saucer... which turns out to also work as a shield, making her still a Barrier Warrior in spirit if not in practice.
Cures Sunshine (and her mascot Potpourri) and Moonlight in Heartcatch Pretty Cure can also cast rather big shields. Sunshine in particular used her Sunflower Aegis to attack back when she made her first appearance.
Cure Beat and Cure Muse in Suite Pretty Cure ♪. While Beat creates her Beat Barrier with a her Lovely Guitar Rod, Muse creates barriers with her keyboard of light, an ability passed by her family.
Cure Rosetta from Doki Doki Pretty Cure is basically an Expy to Cure Mint. Rosetta's attack are only barriers. However, her second attack Rosetta Reflection has also offensive usages, such as Throwing Your Shield Always Works and Catch and Return-Kamehame Hadouken. When the Pretty Cures fight Melan, a dragon who has a barrier that is more powerful than their group finisher Lovely Force Arrow plus Ace Shot, Cure Heart, Cure Diamond and Cure Sword give their powers into Cure Rosetta's shield, creating their new group attack Lovely Force Reflection. This shield is so strong that it breaks through Melan's barrier. Yes, that's right, barrier vs barrier.
Mai from Mai-HiME can use her Element to create short-range forcefields for herself and her friends. Natsuki also gets this ability in the manga version (hers is ice in counterpart to Mai's fire).
Though considering Mai's power mainly consists of pyrokinesis and summoning a giant dragon with its very own Wave Motion Gun, her shield does not really make her a Barrier Warrior.
Sister Yukariko would be a better fit to the trope.
The main characters of Kekkaishi. Comes with the handy bonus that they can make the barriers implode, destroying whatever they made it surround.
They also use some particularly brilliant extensions of standard barrier skills, like a barrier that eats away at anything and everything except the user. And it's implied there are far more powerful barrier techniques out there...
Or they can use their barriers for more mundane but still very useful combat purposes. For example, if an enemy is too fast to be captured by a full-sized barrier, simply make a smaller, faster one around a piece of their body or even their vitals (imploding that section is then an option; the main characters figure that out even when they're still rookiees). If that's not an option, a skilled kekkaishi can instead generate long, narrow barriers that skewer enemies like spears.
It's worth pointing out that Kekkaishi translated literally means 'barrier master'... making this example the prime epitome of the trope.
Orihime Inoue. Her powers manifest as six fairies which combine in different ways to produce shields that have different powers. Three fairies combine to create an extremely powerful Deflector Shield. Two combine to create a healing shield. One lone fairy specialises in a shield that splits two substances apart and can therefore be used to attack and kill. This shield is extremely weak because it's linked to the strength of her killing intent. As a Technical Pacifist, Orihime has very little killing intent. She has, however, learned how to combine it with her Deflector Shield for a four-fairy Attack Reflector.
Also, Hachigen "Hachi" Ushoda from the Vizards. As a shinigami, he was a kidou specialist. As a Vizard, he remains the group's Magic Knight and Barrier Warrior. He's so good and specialised at this that he can even use his barriers and shields to decapitate his enemies. With the aid of a captain (Soifon), he was the only Vizard to beat an Espada.
Nanao Ise was revealed to be this, via creating kido barriers against Haschwalth] so she can assist Shunsui.
In Neon Genesis Evangelion, each Eva and major villain fight through the use of "absolute terror" fields, powerful forcefields that can deflect bullets and even antimatter bombs, and can only be reliably disabled through a stronger "absolute terror" field or through ridiculously big guns. Rather than being pacifistic team players, though, the Eva are frighteningly violent.
In Fafner In The Azure, the Mark Funf has the Aegis equipment, which works like this. Surprisingly, Mamoru and Hiroto in The Movie, since Mamoru is dead by then is one of the more Hot-Blooded members, and fights using techniques inspired by the Gobain manga he reads (he even wears a mask that looks like it in battle).
In the Magical Girl Lyrical Nanoha series, barrier powers are a dime-a-dozen, but some mages are demonstrably better at them than others.
Caro Ru Lushe, from Magical Girl Lyrical Nanoha Strikers. Fullback to her team, because she has shields and an ability to boost others' powers. She also can summon dragons. No, not just that cute little pet Friedrich she has. When she has to, she summons a dragon the size of Godzilla.
In Konjiki No Gash Bell, Tio specializes in protective and healing spells (and has only a single weak offensive spell until volume 20, anyway). In a competition where (the monsters' human partners notwithstanding) most battles are 1-on-1, this presents obvious problems.
There's also Danny, an early character whose only shown ability is to heal himself. Despite this, he comes awfully close to being a Badass Normal, taking out guys with guns without even using a spell. Eventually, he does get shot, but it only takes a first-level spell to get him up again, hinting that had he survived, he'd be nigh invincible. However, he gets his book burned not in battle, but in protecting a museum artifact. Fans speculate that had this not happened, Danny may have made it to the end, although this is somewhat balanced by having his book reader be a little old man. In the manga, when Gash's book first glows gold giving him the ability to use other demon's spells, it is Danny that saves him with his one and only spell, completely healing the thrashing that Gash received at the hands of Clear Note.
Suzumiya Haruhi: Yuki Nagato tends to fight by slamming people with forcefields, although this may be due to the fact that both times we see her fight, she's also protecting noncombatants. This is in contrast to her Evil CounterpartRyouko, who prefers various means of stabbing the hell out of people (spears thrown with telekinesis, regular ol' knives, whatever.)
The Distortion Fields on Martian Successor Nadesico are also useful for offense (and like most Aestivalis weaponry, are an Homage to Neon Genesis Evangelion, above, albeit not as creepy). The most generally powerful attack the Humongous Mecha pilots use involves angling their Distortion Field to a point and ramming the enemy with it, a technique named "Gekigan Flare" as a reference to Nadesico's Show Within a Show. When Aestivalis appear in Super Robot Wars, the Gekigan Flare (or combination attacks involving it) is usually the Aestivalis's Limit Break. Gekiganger fanboys Akito and Gai usually have the Double Gekigan Flare as a Combination Attack. Given that Gai usually survives much longer in a Super Robot Wars game than he did in his own series, you have a surprising amount of opportunities to use it. (It never did get used by Akito and Gai in the series, because they hadn't seen the Short Anime Movie that introduced it yet.)
The SDF-1 was given a barrier early on: the only problem is that they didn't have the energy reserves to power it up enough to cover more than a tiny circle of the ship. The solution was to create a series of 'pinpoint barriers' controlled by trackballs handled by the Bridge Bunnies (not the principal Bridge team, but other three girls specially trained for this purpose). The Number Two then came up with the Daedalus Maneuver, which involved putting all the shields around the Daedalus (which was originally a sea-going carrier acting as both a fist and a docking bay) so it could punch through the enemy's hull, then open up and unload a large quantity of missiles inside the enemy's guts.
Later models of the fighter craft mecha also were given Pinpoint Barriers, and could execute a powerful punch in much the same manner.
Likewise, later models of the Macross-class warships. The original Daedalus Attack was thus renamed to Macross Attack.
Halfway through the original series, the SDF Macross engineers found a way to produce an omnidirectional barrier that could spread outwards, like a sphere, to cover the entire ship. Unfortunately, the feedback from enemy attacks caused it to overload and explode violently, destroying a sizable chunk of Ontario and resulting in the Macross being forbidden from entering Earth's atmosphere again. By the Final Battle, however, it had been perfected into a fully-functional shield.
Nozomi Daichi from The Daichis: Earth Defense Family uses an umbrella that generates force fields.
Although they don't do it often, high-level warriors in Dragon Ball Z can generate shields with their ki to deflect or nullify enemy attacks. Oddly, the one who makes the most frequent use of it is Broly
Mage-type characters in CLAMP works are typically capable of this. Most notable:
Since he started using magic again, Fai Flourite from Tsubasa Reservoir Chronicle is also this. Notably, in a recent chapter of the manga he threw up a barrier and held it against an all out onslaught of magic from two other characters.
The Shinkirou, Lelouch's Mid-Season Upgrade in Code Geass R2, is a strange case. It uses the Absolute Protection Territory, a battleship-class Beehive Barrier whose individual mini-shields can be coordinated by the pilot (but this requires an exceptionally quick-minded pilot, meaning Lelouch is the only one capable of using it properly). Defending is its primary purpose, but not allies; since Lelouch insists upon leading from the battlefield but is a mediore-to-poor pilot, it was made to be super tough so he doesn't get One-Hit KO'd.
There is also a single instance of Lelouch finding a non-defensive use for the shield, near the end of the series: Holding open a hole in Damocles' own shield so that Suzaku and some Mooks can get inside and lead a direct attack.
Megumi Kurogane of Gate Keepers is of the versatile variety, creating giant walls to block enemy attacks, as well as using said walls to crush them. This power is inverted into a piercing ability after her Face-Heel Turn.
Ayeka from Tenchi Muyo! can generate force fields, and also can summon floating wooden blocks that encircle a person and restrain them. Ayeka uses her shields as an offensive weapon by flying towards the enemy. When properly motivated, her shields are large and powerful enough to shatter an entire corridor of one of the most powerful warships every built.
Katsuhito - Tenchi's grandfather, has similar shields, but he only uses them for defense, preferring the Tenchi-ken for offense.
Tenchi has similar powers, but due to his lack of training he rarely uses them. The only time we see him use them in the original series was wrapped around a fist to attempt a killer blow against Kagato while parrying his sword. However, Tenchi's ultimate power - the Light Hawk Wings - are massive shields that can block nearly anything. After unleashing them he fights with the Light Hawk Sword, which is really just one of the shields shaped like a sword.
All of the Royal families Tree Ships also have the Light Hawk Wings. Ayeka's has three, but the Grand Ship Tsunami (who is also their goddess) can form a full 10 wings which is powerful enough to stop an Earth-Shattering Kaboom. Tenchi's wings differ from those of the tree ships, though, in that his can perform "material conversion", which is a fancy way of saying they can do anything. Among other things, Tenchi's Light Hawk Wings have been used to escape from inside the event horizon of a black hole...by sheer brute force, destroying the black hole in the process. Everything in that sentence should be physically impossible, even by the super-technology standards of Tenchi Muyo, which demonstrates just how special his wings are in-universe.
The UC Gundam series has the "I-Field", a barrier that deflects beam weapons. It requires a considerable amount of power to put up (and, earlier on, the generator itself is rather big), such that only large Mobile Armors are capable of using them to any useful degree. They're a defensive measure only until Zeta Gundam, when the Psyco Gundam Mk. II uses 'reflector bits' to generate a localized I-Field some distance away, with which it can deflect its own beam shots so they come at an unexpected angle.
However, despite this being an obviously useful tactic, about the only other Mobile Suit designed with this in mind is the Ex-S Gundam, and it's an overpowered Super Prototype that already has an indirectly firing weapon in addition to its 'reflector INCO Ms'.
Later on, the Crossbone Gundam X3 is built with I-Field generators in its arms, and they're powerful enough to force the Divinidad's weaponry against itself at very close range - much like trying to shoot a blocked gun.
By this point decades of technological improvement have made it possible for a normal-sized mobile suit, rather than a giant like the Psyco & Ex-S Gundams, to operate an I-Field, but the power requirements are still a major limited factor. Especially since "normal sized" has become smaller by this time, with mobile suit design de-emphasizing armor in favor of speed, agility and presenting a smaller target profile. The I-Field generators also produce a lot of heat, requiring 2 minutes of cooldown for 1.75 minutes of operation, otherwise the generators will overheat to the point of destroying themselves.
In D.Gray-Man, Miranda Lotto is the only Exorcist with a purely defensive Innocence. However, it's really, really powerful; she can basically reverse and suspend time within an area around her. In practice, this means that within that area, anyone she wants will have wounds disappear as soon as they're made, and she can reverse damage to objects just as easily. The two big limitations are that it only lasts as long as she has the strength to keep it in place and that every bit of damage reappears as soon as she stops invoking.
Let's not forget Beet the Vandel Buster's Cruss, a water using legendary hero whose shield protects the group as well as rebounding any attack back onto the attacker. Slightly subverted in the fact that said shield can transform into a giant flail.
Heroman: Joey's gauntlet allows him to throw up small but apparently very strong force fields.
Kyle from Psyren can create dense pockets of air with his psy. Not only does he defend with them, but he uses the blocks to crush foes as well as a platforms for maneuvers. His future version vastly improves on the defensive capabilities of them and can block all but the strongest attacks from all directions.
One of the powers of Ryujin's sword allows Yaiba to create an energy shield. Emerald is capable of summoning Barriers and healing people. Actually, she Is the Barrier Soldier.
Taomon from Digimon Tamers. She has other attacks, but they see very little use compared to the forcefield. Her ultimate form, Sakuyamon, is similar, though goes on the offense a little more (her barrier is sometimes the only means of getting into the true enemy's territory without dying horribly.)
Jake Martinez from Tiger & Bunny can create barries and use them offensively, which is how they are used most of time.
One Piece: Bartolomeo, who ate the Bari-Bari Fruit. Subverts much of the other traits of this trope in that he is cruel and selfish, and uses his barriers more for offense than defense.
Griamor from Nanatsu No Taizai uses Wall, a power to use force fields either for defense or offense.
All of the members of the Nase family in Kyoukai no Kanata have the ability to create force fields, referred to as cages, with varying levels of skill.
Susan Storm aka The Invisible Woman in the Fantastic Four, who was given force fields because mere invisibility isn't all that super when your kid brother Johnny can lob fireballs. As a veteran superhero, she's gotten quite good at using her powers offensively, such as threatening to use them to create a brain embolism/aneurysm at one point.
The Invisible Woman has easily taken out the other members of her team with force fields, as well as knocking out both The Hulk and She-Hulk by cutting off their air. This was mocked in an issue of Exiles, implying she brags about the feat often.
Dr. Doom has stated, on a number of occasions, that Sue is easily the most powerful member of the team. This is backed up by a few of higher end feats, which include killing a Celestial, who are essentially space-roaming gods. She is, to date, the only Earth-based Marvel hero to accomplish this. And in fact, very few characters of any level of power have ever accomplished such a feat; even another Celestial would have great difficulty killing a Celestial.
Suffice to say, while her personality is still the mothering/nurturing type, and the original stories featured her as a sometimes-invisible Distressed Damsel, Sue has gone a long way towards subverting this trope when it comes to how her powers are used.
Melissa Joan Gold aka Songbird from the Thunderbolts creates pink solid-sound energy constructs quite similar to Sue Storm.
The resemblance was noted by Sue Storm's son Franklin Richards:
Franklin: H-Huh? A bubble like mom's bubbles! Except — I can see it!
Subverted with Captain America, whose sole weapon - his iconic indestructible shield - is, when thrown, a great offensive weapon against most people.
During a period when his shield was lost or destroyed (around the fifth or sixth time... it happens to him a lot), Cap was given an energy shield which acted in this way. Being a traditionalist, he quickly went back to the old shield once it was found/rebuilt.
He's been using it more recently and in more creative ways, such as wiring up his forcefield with his blasters to blast the area in a burst so he wouldn't get mindcontroled. One of the reasons he didn't use it so often was because it might weaken his immune system.
In his very first appearance, Magneto created a forcefield around an entire military base to keep the X-Men away. Occasionally, writers still remember that he can do that.
The X-Men villain Unus the Untouchable is a villainous example of a Barrier Warrior, with the mutant power of being able to project an impenetrable force field around himself. Rather than being kind and caring, Unus acts like a Jerkass because he thinks his power prevents anyone from being able to stop him. He's generally right...until the superhero he's fighting finds some way to either circumvent the field's protection or comes up with a creative way of shutting it off, at which point he's easy prey. Turns into Blessed with Suck when he loses control of his field and suffocates to death when it grows so strong it repels air.
One of Magneto's Acolytes, Unuscione (who, depending on the depiction, may or may not be Unus' daughter or other relation), takes the power one better in that her force field takes the form of an exoskeleton, not only protecting her from harm but allowing her to be an active combatant. The young trainee and later full X-team member Armor's power works much the same way.
Subverted in Buffy Season 8. Giles fights a sorcerer with much greater proficiency in magic than him and is mocked for casting a basic barrier spell that any competent mage could tear through. Giles however, casts the barrier inside his opponents head and as it expands, his skull explodes from the pressure. Brutal killing with a simple defensive spell.
Since Invisible Woman has this, so doesShrinking VioletViolet Parr (though a more limited version). She uses it for trapping mooks, cutting off electrical circuits, and as a super-hamster ball (particularly when combined with her brother's Super Speed).
Taken Up to Eleven in the comic adaptation. Her force fields become massively upgraded, complete with purple sparks resembling electricity, courtesy of a power-enhancing virus.
The Matrix: A good few scenes with Neo have him using this power.
Bella in Breaking Dawn is able to protect herself and her allies from the mental powers of enemy vampires.
Kharl in The Saga Of Recluce uses Order Barriers as his main ability often using them to not just protect himself but to suffocate enemies while deflecting firebolts at armies of soldiers.
Harry Dresden of The Dresden Files makes frequent use of this trope. Other wizards do too, but we don't see it on screen as much. Because wizards aren't much more or less physically fit than muggles, but all of them are a much lower weight class than supernatural beings, this trope is life or death for them.
Harry starts the series with a simple focus designed to make a kinetic shield that he can shape at whim, though he usually uses sections of a sphere to protect himself. Eventually, someone cleverly uses a flamethrower to attack him - his shield catches the burning fuel, but the convection burns him badly, damaging his shield bracelet in the process. When he remakes it, he learns both the specific mistake and the meta mistake, and makes the new bracelet more powerful and flexible, at the cost of a larger power draw. It now blocks solid objects, heat, sunglight, sound, mental energy, and the kitchen sink.
One of the big points of the series is that almost everyone (including Harry himself) can dish out more than they can take, so the attention Harry puts into being the Determinator over the course of the series contributes at least as much to his Famed in Storystatus as his raw power or his exploits. As he notes, the number of things that he's survived pissing off would look really scary to someone who doesn't know all the details of his story.
Carlos uses a shredding shield - instead of stopping attacks, it diverts and breaks them up. For example, it shreds bullets into something resembling sand. Harry notes that it's much more efficient than his own shield bracelet.
Harry teaches Molly shields with snowballs. He himself learned with baseballs. Luccio taught Morgan with rocks.
The Merlin raised a ward that stopped the entire Red Court cold, at the drop of a hat.
Derek Huntsman of the web-novel Domina has the power to create barriers. Quite fitting for someone with Chronic Hero Syndrome, though a little odd for someone in the position of The Hero.
Dune The Atreides family specializes in shield-based combat, which is a detriment on Arrakis.
Seeing as force fields in this setting (And the offending laser weapons) explode violently when hit by common laser beams, it's surprising that noone comes up with the bright idea to just set up a remote controlled laser cannon, aim it at any shielded target and watch the fireworks.
People have. Seeing as the resulting explosion would be indistinguishible from a nuclear bomb, which is illegal in the setting, it's not really a good idea to do that.
Additionally, what exactly determines the yield of the resulting explosion is unknown and the devices are too expensive to experiment to figure it out. You can fire an orbital-equivalent beam at a city-sized shield and just get a little spark that shorts out one or both systems, and you can fire a hand weapon that's basically an overvolted laser pointer at a personal shield and obliterate a thirty-mile radius of city. This unpredictability makes the effect almost impossible to use tactically, though terrorist-style organizations that don't really care about collateral damage, like the Fremen, have pulled it out against foes that otherwise overmatch them, like the imperials.
Force-Sensitive Tash Arranda, in Galaxy of Fear, can sometimes, in emergencies, call on the Force to create a kind of shield around herself. Since she's untrained and has no idea what she's doing, it's not something she can control or really rely on during the series.
Live Action TV
In Smallville, Wes Keenan is able to generate force fields that are said to be able to withstand anything less than a small nuke.
Roswell Max was able to create psychically-driven barriers like this with his alien powers.
The abjurer in 2nd and 3rd edition is a specialist wizard who focuses on defensive magic, including spells that create magical force effects, such as mage armor and shield. A 3E Prestige Class, the abjurant champion from Complete Mage, combined the abjurer's protective magic with a warrior's skill at arms to make a literal Barrier Warrior who relies on magical force barriers rather than physical armor.
Another 3rd edition Prestige Class, the Initiate of the Sevenfold Veil, lets a wizard surround himself in multiple layers of different-coloured barriers, each of which blocks a different form of attack and has different effects on anyone who tries to pass through it. At higher levels they can shape the barriers into walls and bubbles.
With the right combination of feats it is possible to make a fairly effective fighter who wields dual shields.
Both the swordmage and the wizard classes from 4th edition have shielding capabilities. In addition to a swordmage's passive warding, a shielding swordmage effectively absorbs one enemy's dealt damage every turn. The staff wizard, on the other hand, can use shielding type spells to boost his defenses in order to make attacks straight up miss him.
The Magic Knight magus class in Pathfinder can gain an ability to immediately conjure a barrier in the face of an incoming attack. Their spell list also contains many personal defensive abilities.
Mage: The Awakening has the obvious "protection from" style effects from most of the major arcana (death, mind, forces, etc), but a specialist in the "space" sphere really lives and breathes this trope. It is a common build to simply take three or four points (out of five) in spaces to get the ward and ban abilities, which allow you to simply forbid anything you can sense from a space, then take a single point in every other sphere (allowing you to detect basically anything). In a setting where a sleeping mage is an easier kill than most vanilla mortals, and much of the supernatural world wants to kill them, unsurprisingly the mage that carries his own impregnable fortress with him is a valuable ally.
For bonus points, space also allows teleportation, so you get the obligatory offensive use of the barrier as well. "No one but me may enter or leave this circle" (with the enemy already in the circle, increase duration to several months, walk away.
While his personality is a total blank, Ness from EarthBound has the power set and is arguably an example who is also The Hero. Due to his party's ability setup, Ness is a case where this actually helps him shake off enemy attacks instead of receiving The Worf Effect.
Actually, Poo can also use a similar shield setup to Ness as well, and in fact a BETTER version which allows him to shield all his allies at once, whereas Ness's shields can only be added to one ally per turn.
And Paula is furthermore the best example in Earthbound itself, as her personality seems to be similar to a barrier warrior even though she's also a mix of a Glass Cannon and Squishy Wizard. Also, Ness and Poo's shields affect physical damage, and only at best cut it in half (while sometimes deflecting the other half). Paula's shields, are meant to shield from PSI attacks, and they FULLY shield affected characters instead of just reducing damage, and they can also deflect PSI completely. Using PSI Shield Omega in the Starman DX battle plus the Starman DX using PSI Starstorm Alpha = scrapped Starman DX.
Still more, Lucas possesses half-damage reduction forms of both the Physical and PSI shields [both blocking and deflective] in Mother 3 and a lot of his use in combat relies on him using these shields in the later half of the game.
In City of Heroes the Defender archetype uses this type of powers, and shares weaker versions of them with the Controller; additionally villains get their own versions in Corruptors and Masterminds. Four of the power sets available work primarily by putting shields of some kind on other characters (or in the case of the Mastermind, a bunch of henchmen!), including Force Fields, Ice Shields, Sonic Barriers and Thermal Radiation Shields. The other Buff/Debuff sets vary widely but several include auxiliary barrier powers. All of these various powers are so potent that a team composed heavily of support characters can truly be Nigh Invulnerable.
Anarchy Online has this in the Soldier profession, who can not only create Deflector Shields around themselves, but also around others. However, the profession is focused around dealing ranged damage to an enemy.
Guarlions (and similar machines) in Super Robot Wars Original Generation can generate a forcefield when moving at high speeds. Naturally, one of their strongest attacks is to ram things hard. Similarly, the Super Robot Giganscudo will also use its fields to slam into the enemy, either when using its massive weight as a weapon, or by grabbing the enemy from a distance and slamming it into its field-shrouded mass.
In the MMORPG Flyff, an entire class, the Assist, as well as its higher-level counterpart the Ringmaster, is dedicated to buffing and healing.
Well, really, that makes them The Medic, as while many skills increase HP or provide an increased Dodge or Block rate, only 2 skills of the Ringmaster, Protect and HolyGaurd, and 2 of the Seraph's skills, Raiment of Rhisis and Soul of Rhisis, actually boost defense.
In Dragon Quest IX, a Paladin's Limit Break, Knight Watch, protects the entire party from physical attacks by making all enemies attack him AND making him immune to said attacks. It can be a major lifesaver in the late game.
World of Warcraft has several classes capable of becoming Barrier Warriors. Priests can make protective barriers out of an allies' soul, with some priests actually enabling these shields to reflect damage. Paladins go one step further into the defensive variety, able to make themselves invulnerable to damage, make an ally invulnerable to physical (but not magical) damage, or sacrifice themselves to make an ally immune to absolutely everything but removing them from combat. Finally, Warriors can turn their shields into fully offensive weapons.
More recently Priests specializing in the Discipline tree have become a full embodiment of this trope. Discipline Priests specialize in creating shields to prevent damage rather than to heal it.
Warriors also have an ability called "Shield Wall" which temporarily reduces all damage they receive by half. The animation looks like military shields dancing around their bodies. Similarly, a Paladin's "Divine Protection" spell halves all damage the paladin receives for several seconds; the reason a paladin would choose Divine Protection over their more powerful total-invulnerability spell is that the latter convinces monsters to attack their comrades instead.
Mages are probably the ones with the most buffs that act as shields, most of which also can be used outright offensively just by being there and getting hit by enemies. They have molten armor, which on top of lowering the attacker's crit chance on the mage actually does fire damage to the attacker. They have frost armor, which raises their armor value and, depending on how far down you go into the frost specialization of their magic, will slow any melee attacker to varying degrees and outright chance-on-hit freeze them in their tracks. THEN they have the literal stop-all-incoming-damage shields, Mana Shield (which eats through lots of mana and kinda sucks) and Ice Barrier which on top of being a very effective defense will also explode and freeze all enemies in range of the mage when it takes its max damage. Oh, and they have two "wards" that absorb any incoming fire or frost damage and, if glyphed, can actually convert part of said absorbed spell into their own mana.
Warhammer Online has several healer classes with barrier or damage reduction abilities, most notably the Chaos Zealot (and its stunty equivalent the Runepriest) - they have barriers to shield their entire party, single targets, or prevent damage to themselves; they can buff to reduce incoming magic damage; they have tactics to increase the armor of allied players or put up a barrier on themselves; finally, they have two separate morale abilities to absorb damage across the party.
The Golem Asgard from the Wild ARMs series specializes in barriers, and is supposedly the defensive, friendly golem. However, since its barriers disintegrate anything that touches them, they're primarily used offensively, sometimes leading to One-Hit Kill attacks in games where you fight Asgard. Barrier Fist! Barrier Storm!
In nearly all of his incarnations, the Carbuncle summon is the magical counterpart to Golem, projecting a reflect shield over your party to deflect most magic spells.
The Shield Dragon from Final Fantasy V is an enemy with a permanent reflect spell. It attacks by casting spells on itself, because in this game a spell can be reflected only once.
At various times in several games of the series, it's beneficial for the player to utilize the Reflect spell in non-traditional ways. For example, you're very unlikely to win the battle against Asura in Final Fantasy IV unless you cast Reflect on her, since unless you're at an absurdly high level she'll heal faster than you can inflict damage, and also has very strong physical attacks of her own.
And against the Shield Dragon itself, if you want to hit it with magic, you'll have to duplicate its own strategy and bounce spells off your own Reflect-shielded party members.
Several rings in zOMG! are shield based, but the closest thing to an outright barrier warrior is the Chef (yes, chef) Ring Set. In addition to receiving a natural armor bonus, the Chef also has access to Teflon Spray (one of the most useful Armor Buffs in the game), Pot Lid (which can deflect ranged attacks with ease), and Meat (which can nearly double your maximum health). Due to the energy based nature of all zOMG! skills, it could be said that the Chef set is actually summoning G'hi Shields to protect his/herself and his/her allies. Or, you could pretend that he/she is really spraying Teflon all over themselves. It's that kind of game.
Unfortunately, a recent update that rebalanced the rings and ring sets removes some of this: the Chef set trades Teflon Spray for Hack (an attack ring), and its bonus is now to Dodge rather than Armor. However, apparently it is now considered the new "best" set to have. Plus Dodge controls whether you're hit in the first place, so that can be even better than the best defense.
Note that Mirror is unique in this regard: while blocking with it active, Kirby does contact damage while being invincible. It's actually possible to beat a few bosses this way.
Some Pokémon moves work as barriers, such as Protect and Detect, which prevent all damage, but usually tend to fail when used two turns in a row. However, against the Pokemon Slaking, which is extremely powerful but can only attack every other turn, such a Pokemon is Nigh Invulnerable. There's also Reflect and Light Screen, which temporarily halve the damage dealt by physical and special moves, respectively. However, there are certain moves that can break through these barriers. The move Feint will hit a Pokemon that is using Protect or Detect, and Brick Break and Defog will get rid of Reflect and Light Screen. Defog also gets rid of Safeguard (protects against status conditions) and Mist (protects against stat lowering).
Guardian Heroes (on the Saturn and XBOX LIVE) has Nicole. While she fills a variety of roles such as White Mage, Luck Stat, Lightning Bruiser, among others, one of her more prominent spells creates a giant barrier dome that gives your party a chance to regroup or set up ranged attacks. Being a shield maiden isn't all defense; an offensive use of Barrier is running up to enemies and activating it like a battering ram, crushing them against walls or the screen edge (which hurts even if they try to block).
Mega Man X also includes Armor Armadillo's abilities, which let X fire rolling barriers along the ground as projectiles. The special charged version creates a barrier over X that blocks attacks and can do damage to enemies when touched.
In The Elder Scrolls III: Morrowind the demigod Vivec's main job is maintaining magical barriers that hold back the blight. He doesn't particularly like his job, but has no choice particularly since he was one of the ones responsible for creating the problem in the first place cares a lot for his people and feels responsibility towards those believing in him.
In Mass Effect, all combat armor uses "kinetic barriers" known colloquially as "shields" to intercept bullets. Most characters get the Shield Boost ability, which rapidly recharges shields in combat. Tech based characters get omni-tools and the Electronics talent, which add to shields (especially Electronics). But the biotic characters get the Barrier talent, which generates temporary shields from their own bodies. Maxed out, Barrier grants nearly twice the shielding as any other character and lasts nearly as long as it takes to cast it again. However, the three biotic classes can also get an ability Barrier Specilization, which dramatically lengthens the ability's duration and shields, while providing constant regeneration. The end result is that a Squishy Wizard style character can take as much dakka as the game cares to throw at him, with only a handful of attacks posing any kind of threat even at the highest difficulty levels.
In Mass Effect 2, the Sentinel class has access to the 'tech armor' ability, which projects a form of holographic armor over your character's normal combat armor, providing a tremendous boost to your shields. Unless your (buffed) shields are depleted, it will never go down. When it does go down, an explosion is triggered, which is great for gaining some breathing room when surrounded by melee enemies. As you put more skill points into it, it becomes far stronger, eventually to the point where it doubles your shields. The thing that makes it really gamebreaking is that when you do cast it, it restores your shields up to their buffed maximum, even from entirely depleted shields. Even better, it can usually be cast again as soon as your shields go down, providing you with virtually limitless shield power (only if you're willing to mostly forego the Sentinel's other tech and biotic abilities, which also trigger global cooldown). Essentially, if used right, it makes you invincible. Fun stuff.
One segment of Mass Effect 2's final mission requires a biotic character to cast a barrier bubble big enough for the whole party to shelter in, for several minutes. Choose the wrong biotic for the job, and one of your party members will die as a result when the barrier fails prematurely.
Mass Effect 2 and Mass Effect 3 also gives us the vanguard, with the biotic charge ability. Essentially, when Shepard uses this ability, he turns himself into a miniature mass relay (those big things that hurl the Normandy across the galaxy) and slams into his enemies at incredibly high speed, using his biotic barrier to damage and throw his target.
Mass Effect 3 multiplayer also includes the Asari Justicar, which possesses the Biotic Sphere ability, a biotic bubble shield. For added benefit, it can also be upgraded to damage enemies that enter the sphere, though choosing that upgrade lessens the defensive benefits of the ability.
On at least one occasion in Mass Effect 3, biotics can be seen casting barriers as an ad-hoc patch in a broken fortification, until something solid can be dropped in place.
Stacking Arcane Shield, Fade Shroud, and Rock Armor onto a mage in Dragon Age makes them tougher than any warrior in the game. Yes, the Squishy Wizard just out-tanked the tank.
To say nothing of the absolute Game Breaker that is Shimmering Shield, which, at the cost of a significant mana drain, makes the mage essentially Madeof Iron, with extra armor, 75% resist all magical damage, and 75 physical and mental resistance.
In Halo: Reach, a barrier armor ability is available called Armor Lock that protects the user from all harm at the cost of being unable to move when in use. It also bursts outwards in an EMP when it drops. Note; All harm means just that. Unlike the Bee Hive Barrier from Halo 3, Reach's shield ability can stop a speeding warthog like... Well, Superman, really. Going from a sitting duck to the man of steel in a split second really makes your day, as the jeep that was about to crush you explodes and goes tumbling away.
Cole from inFAMOUS eventually gains an impenetrable shield ability, and can even get an upgrade that lets him absorb energy from deflected attacks.
A skilled Exdeath player in Dissidia: Final Fantasy will suffer many attacks and actually be hit by none of them, on account of his excessive amount of guard, reflect and counterattack skillsnote he has several rather slow and telegraphed attacks, but, upon blocking an opponent's attack with one of his shielding abilities, he can activate nearly any of them, both HP and BRV, at lightning speed, even if he doesn't have them in his current moveset, or even learned them yet. He has six different blocks in total, five magical ones in addition to his default physical block. A player match between Exdeaths is... silly.
In Second Sight, just about every single psychic in the game has the ability to create force fields, from the bulletproof NSE shock troops to the Zener Children- who are all but invincible on top of being some of the most powerful psychics in the game. Depressingly enough, the main character doesn't get this ability.
Fairess, one-third of the Sylph summon from Tales of Symphonia uses a shield as her primary weapon.
Use of the Riot Shield in the Modern Warfare games, though care must be taken to avoid getting shot in the legs or back.
In the Touhou series, all of the characters have barrier shields in the fighting games, although some are made of physical materials such as ice, most of them are just magic energy.
Reimu Hakurei is a subversion. First, her barriers are extremely offensive in nature. Second, she's the main character.
In The Lost Vikings you control three viking warriors, one with the power to jump, and to smash through things with his head. One with a sword and a bow. And one with a shield to protect himself and the others from enemy attacks. (Although he can also use it to glide, and for the incredibly useful task of providing a platform for the others to stand on.)
In Tales of Vesperia, Estelle embodies this trope. While she is essentially the designated healer, she can conjure a force field spell to render allies immune to damage, as well as fights with a sword and shield, having the highest defense of all characters.
Also in space, Star Wars: Empire at War, where the Rebellion's larger vessels may boost shield regeneration in exchange for speed and attack power.
StarCraft II is a curious example, since it doesn't involve a character but a unit - the Protoss Sentry, whose Force Field ability can be devastating in the hands of a skilled player, especially when used to cut off enemy units passing through a chokepoint.
In Guild Wars, the Monk has a substantial number of shielding powers, ranging from damage limiters (some of which reduce the max damage any one can take; others lower the damage each consecutive attack deals) to blocking powers (giving the subject an increased chance to block attacks completely) to converting all incoming damage to healing. The Ritualist has a few abilities with similar, but less effective, effects.
Aqua in Kingdom Hearts: Birth by Sleep has some useful Barrier powers. Her default guard is a magic barrier, her counter attack after blocking is to shatter the barrier, and she has the ability to rush enemies with a barrier up.
In Kingdom Hearts II Sora's most powerful spell is the Reflect line of spells, which, after successfully guarding, unleashes a spray of Light equal to the enemy's attack power.
There is also a wizard nobody that falls into Demonic Spider territory due to the use of indestructable transparent blocks that it uses for both offense and defense.
358/2 Days gives us the Barrier Master Heartless, whose sole reason for existing is protecting its allies and itself from damage until it is defeated.
Unusually for a Bullet Hellshmup, Hellsinker heavily uses a suppression shield as a gameplay mechanic. The shield, which looks like a blue circle surrounding the player's craft, can damage enemies and slow bullets down. Some attacks are almost impossible to avoid without it, but other times using it will land you in a world of hurt.
Fossilmaiden also has an extra shield attached to the hilt of her Laser Blade.
Mori Motonari of Sengoku Basara combines this with Trap Master. One of his abilities includes creating light barriers that bounce people off of them. If done correctly, he can make trap enemies between two barriers, bouncing them off each other and killing bosses incredibly quick.
One of Alex's abilities in Prototype where he can summon a shield out of biomass that can deflect bullets. With the right aim you can kill an entire army with their own bullets. Or you can simply run threw them as if you were a snow plow.
Elh from Solatorobo, though the barrier spell is extremely draining and only used as a last-ditch resort (and only in cutscenes; you aren't given the option of asking for a little help during a fight).
In Bastion the combat duty of Caelondian caste of Menders was to carry huge Bulkhead shields, which you can also use.
Invisible Woman shows up as a character in Marvel Avengers Alliance, with a massive array of shields on shields on shields as both her passive and active abilities. Some other heroes like Iron Man, Doctor Strange, and the Scarlet Witch also have lesser shields available.
The Engineer class in Torchlight II has the Forcefield skill, which when activated, gives him and nearby allies a Deflector Shield for 30 seconds. It absorbs up to a certain amount of damage from almost any source. At higher levels, the shield can absorb ludicrous amounts of punishment before finally failing.
Champions Online has this as a major part of the Force powerset, with Force characters able to make shields to protect themselves and allies, as well as other shields that can contain enemies and prevent their movement. A few Mentalist (psionics) powers have similar effects, with the protective telepathy shield having the additional affect of being able to heal whoever it is protecting.
An update called the Two Cities Update in Team Fortress 2 has since given this as an upgradable power for the Medic in MannVersusMachinemode. He can deploy a mobile barrier shield centered on him that negates projectiles and damages enemy robots if they touch it.
Young Anja Donlan of Gunnerkrigg Court had the ability to create spherical purple shields. Later, she combines this power with an etheric computer (designed by her and her husband, Donald), expanding its usefulness: using it, Donald gains the ability to create shields, and Anja is able to bind demons.
Laura of Collar 6 was recently revealed to be this.
Wayward Sons: Ipalyo. He can shape his barriers into secure platforms to carry allies around, and they withstood an explosion which caused tremors beyond visible range.
Guardian Angel of PS238 is one, with her power being a semi-aware forcefield that protects her from all harm. This turns out to be Blessed with Suck when it turns out that she's had it since birth, and has protected her from everything including illnesses and the minor injuries induced when receiving medical injections, meaning that she has no immune system to speak of. This causes big problems for her when her powers get turned off.
In Zodiac, Virgo is able to protect herself like this. However, it isn't invincible, and doesn't completly protect her from heat.
Deflector is a more traditional Barrier Warrior, using planes of force as both defense and weaponry. The Great Wall, one of China's greatest heroes, shares the power set.
The heroic Dove is a Martial Pacifist who specializes in evasion, blocking, and misdirection in combat. He's an expert at somehow finding convenient trees, walls, cars, and so on to duck behind just as the bad guys attack. He only goes "offensive" when he absolutely has to.
Wallflower of the Whateley Universe: spherical shields, invisibility, and the psychic ability to 'see' when inside her 'invisibility' sphere.
North Dakota in Red vs. Blue has a Beehive Barrier as his special armor ability. His AI Theta helps him do some impressive tricks with it, including switching it on and off rapidly to allow him to fire out of it while still being protected... and using its usual two-sided impenetrability as an offensive weapon when erected around enemies.
Dovetail from Worm has the power to make soft, somewhat easily breached force-fields. She however can make a lot of them very quickly.
Several other characters can create force-fields, but the best seen so far is Narwhal, who can create them inside people, which can damage even Endbringers.
In Brennus, Tartsche becomes Nigh Invulnerable if he's standing still, and can choose to extend this defense to anything or anyone he's touching. By Word of God, even if you destroyed the ground beneath him (and he habitually extends his power over it anyway), he would just float in the air until he chose to move. He uses this to ignore the recoil and sound when fighting Guns Akimbo with machine guns.
Arguably, Ratchet from Transformers Animated. His main ability comes from his wrist-mounted magnetic field generators, which he often uses to create shields against enemy attacks. They're a bit more malleable than the average Deflector Shields, though, and they can can just as easily toss enemies around or push objects into them.
In the original Transformers, Trailbreaker also had force field powers.
Toa Tahu wears the Mask of Shielding, which protects him against attack by creating a bubble shield (which is covered in Instant Runes in the Flash animations but not in the movies) capable of protecting him from a waterfall of lava. When he becomes a Toa Nuva, the mask gains the ability to protect others as well. However, it does not protect against attacks that the wearer is unaware of since it has to be activated manually, and sometimes you can get around it by doing something that would not be interpreted as an attack — for example, Nuhvok-Kal managed to reach through the shield with the power of his gravity weapon and cause Tahu to faceplant, bringing the shield down.
Tahu's also a subversion as far as personality is concerned, as he's as Hot-Blooded as they come and not prone to running and hiding behind cover (though he's mellowed a bit in that regard).
Eric the Cavalier from the animated Dungeons & Dragons is issued a shield that projects an invulnerable force field. He doesn't use it very often, though, because his usual reaction to danger is to run away and hide.
Maguro of Sushi Pack can use her psychic powers to create a force field that's large enough to shield the whole group, and strong enough to keep anyone under it from being crushed, even by beings much, much larger than she is.
In Wakfu, sufficiently powerful magic users generate shields at a whim. Both the villain Nox and the benevolent dragon Grougaloragran project force shields to protect themselves from each other. There's also the whole class of Fecas whose gimmick is having cool shields.
In Challenge of the GoBots, Leader-1 had this ability. However, it took a lot of energy and was exhausting for him, so he could only maintain a forcefield for a couple of minutes at a time.
In Rollbots, Lance's only power is being able to create force-fields around himself, which he uses in more or less every fight he is in. It's ironic, because he has demonstrated on at least one occasion some fighting prowess.
