Wyldstyle (The LEGO Movie)
- Voiced by: Elizabeth Banks"I'm Wyldstyle... and I'm not a DJ!"
Along with friends Gandalf and Batman, Wyldstyle travels from dimension to dimension to stop Lord Vortech.
- Embarrassing First Name: Lucy.
- Hair Flip: It's one of her Idle Animations, complete with the swiveling-hairpiece reference.
- Just Friends: With Batman, since he's from his respective LEGO game series, and is not the one from The LEGO Movie.
- Ms. Fixit: One of the few characters to possess the "Master Builder" ability. This allows her to recreate otherwise difficult-to-build constructs in a snap.
- The Smurfette Principle: Wyldstyle is the only main female protagonist, but the other character packs do contain their own female characters.
- Stylistic Suck: Her animation, while not as choppy in framerate as the characters from Midway Arcade, looks more like an actual Lego minifigure hopping around than either of her travelling partners, with mostly nonexistent knees and elbows. This is to emulate the style of her movie.
- This Looks Like a Job for Aquaman: Wyldstyle is one of only three characters who can use a scanner to detect invisible objects (the others being Bad Cop and Chase McCain).
- Wall Jump: Her Acrobatics ability allows her to cling to and hop between sparkling walls that share the same color palette as her hair.
Gandalf the Grey (The Lord of the Rings)
- Voiced by: Tom Kane"I am Gandalf the Grey!"
Straight from Middle Earth, Gandalf helps the trio with his magical powers.
- Accidental Misnaming: Mistakes Doc Brown's famous oath of "Great Scott!" for his name.
- "Awesome McCool" Name: When Sauron refers to him as "Gandalf Stormcrow", Wyldstyle decides that "Stormcrow" would make a good alternate for her own codename.
- Catchphrase: "You shall not pass!"
- Hey, That's My Line!: He gets defensive of it when The Tri uses it.
- Fish out of Water: While true of all three characters to an extent, Gandalf hails from a fantasy world (compared to the more kitchen sink approaches of DC Comics and the LEGO Movie) and has a lot of trouble with less fantastic concepts.
- Funny Background Event: When interacting with the TARDIS, he gets electrocuted and turns into Gandalf the White. He turns back into Gandalf the Grey upon being electrocuted a second time.
- Heroic BSoD: He has a brief one when he learns Sauron is present in Metropolis. Batman and Wyldstyle quickly snap him out of it.
- Hypocritical Humor: Gandalf likes to play up the eccentric old man trope but is baffled by others like Doc Brown and The Doctor.
- Lighter and Softer: Again, unlike the films and books he's physically based on, Gandalf is much more genial, and less world-weary. Presumably this is because there's already Batman serving as the grouchy one of the trio.
- No Indoor Voice: Fond of shouting.
- Rage Quit: Gets fed up of being mistaken for Dumbledore in his Meet That Hero sketch featuring Newt Scamander and Tina Goldstein.
- Sarcasm-Blind: He thinks that GLaDOS has a positive attitude when she "compliments" them on completing a test.
- Weapon of Choice: His Magic Staff, the Staff of Power. In close-range combat, he can swing it around to attack and at range, he can fire magical bolts that harm enemies and destroy objects. He can also use it to emit a shield of light, or to illuminate dark areas that characters without a light source cannot traverse.
- Wizard Classic: To be fair, he is the Trope Codifier. Also, lampshaded in the Gauntlet Parody; if low on heath, the announcer will say "Wizard needs food badly". (The Wicked Witch also gets this)
- Wrong Genre Savvy: Given he's from a fantasy setting, this was bound to come up. For example, when dealing with the Weeping Angels, he thinks they're a case of Demonic Possession, rather than being creatures that just turn to stone when you see them.
- Voiced by: Troy Baker"The Dark Knight rises!"
One of DC Comics' most enduring and loved characters, the Caped Crusader from Gotham helps the team with his cool and expensive gadgets.
- Attack! Attack! Attack!: Not actually done, considering how every LEGO boss is, but with boss fights he thinks to call Oracle for advice on how to beat their opponent, only for him to change his mind and say "Ah, I'll just keep hitting it."
- Ascended Meme: He occasionally uses "I'm Batman." as an explanation for something he's capable of doing.
- The Comically Serious: Occasionally expresses confusion with what's happening in his recognizable gravelly voice.
- Composite Character: He's a mix of many incarnations of Batman, taking most of his design and personality cues from the Animated Series and throwing in several references to the Batman: Arkham Series and The Dark Knight Trilogy. He can also become his incarnation from The LEGO Batman Movie when in said world.
- Cool Car: His personal Batmobile, the only vehicle included in the Starter Pack.
- Good Old Fisticuffs: Fights bare-handed as his standard attack.
- Grumpy Bear: Batman complains about many things. For instance, how the loading screen vortexes are annoyingly bright.
- Just Friends: In the interests in diversity between the all of the franchises present in the game, this is the Batman from DC Comics and his respective game series. He's just met Wyldstyle, and not dating her.
- The Leader: Generally takes the lead in the groups adventures, and is often the one most recognized by the villains.
- Nice Job Breaking It, Hero!: Batman is the one responsible for scattering the keystones across the dimensions, as a result of escaping Vortech at the beginning of the game.
- Other Me Annoys Me: He meets up with his counterpart from The LEGO Movie. They don't get along.
- Phrase Catcher: Quotes both "I ain't afraid of no ghost." and "Don't blink." in the appropriate levels.
- Quantity vs. Quality: Compared to The Lego Movie's Batman - he throws fewer Batarangs, but his actually come back to him.
- Red Oni, Blue Oni: The blue to LEGO Movie Batman's red. Also the Blue to Wyldstyle's Red. All for being more calm and collected compared to those two.
- Sissy Fight: The Two Batmen get into one when they first meet.
- Weapon of Choice: The Batarang. It can be used as a ranged throwing weapon, but can also be used for solving puzzles that require its use.
- Voiced by: Joel McHale"Stuck, huh? Don't worry, you're only human. Or...maybe some kind of mammal. I can't tell."
Short for Xperimental Portal Operator. After being banished by Lord Vortech, he allies himself with the heroes in their quest to stop his plans.
- Big Good: Turns out to be the one who set the heroes on their quest to locate the keystones and foundation elements.
- Disney Death: He seemingly dies after the Joker 'puts a smile on his face'. The Doctor manages to repair him, though.
- The Ditz: X-PO is not quite right in the mainframe, to put it mildly.
- Epic Fail: He claims to have somehow fallen asleep in rift-making class, as in while he was supposed to be learning about the thing he's designed to do.
- HeelFace Turn: Initially works for Vortech in the beginning, but changes sides after Vortech tries to kill him.
- Innocently Insensitive: He occasionally says very condescending things, but by all indications doesn't know they're insulting.
- Laser-Guided Amnesia: When he broke him up at the beginning of the game, Vortech also removed X-PO's knowledge of where Foundation Prime was.
- Meaningful Name: Not only does it stand for the above, but he provides most of the exposition for the story.
- Original Generation: He's a new character created for this crossover game.
- Ridiculously Human Robot: Not in appearance but in personality and mentality. He somehow fell asleep when learning how to create rifts and is seen drinking at one point.
- Suspiciously Similar Substitute: A robot with 3 characters in his name (the last two being PO) and providing the heroes inside details? Hmm... perhaps the otherwise exiled Star Wars isn't completely absent after all.
- The Voiceless: He temporarily becomes this in "All Your Bricks Belong To Us". If the player tries to contact him via a Hint Stone in the Gauntlet maze, his hint appears accompanied by a sound from the original game, rather than one of his stock quotes.
- Voiced by: Gary Oldman
The ruler of the planet Vorton, who seeks to gather the Foundation Elements needed to control all of reality itself.
- Attack of the 50-Foot Whatever: Can shape-shift into a massive minifigure, and does so in the 1800's era Hill Valley and the final battle.
- Bad Boss: Seems to be insulting the other villains whenever he's with them.
- Big Bad: Of Lego Dimensions itself, and implied to be the one for the Midway Arcade level pack as well.
- Celestial Body: His body looks like he is made out of a galaxy.
- Easter Egg: The game has dialogue for the cancelled Lord Vortech Fun Pack coded into it, but inaccessible without hacking.
- Evil Is Hammy: The way he speaks.
- Final Boss: Of the main story in "The Final Dimension".
- From a Single Cell: At the end of the main story, an innocent minifig approaches a brick fragment, seemingly of what remains of Vortech after his imprisonment...then he touches it, causing his skin and sleeve to become Vortech-like, and he cackles. It's unknown whether this was a Thanatos Gambit, a case of As Long as There is Evil, or Xanatos Gambit.
- Generic Doomsday Villain: Essentially is just trying to rule the universe- we haven't got any backstory for him, like who he really is or why he wants to rule the entire multiverse.
- Humanoid Abomination: He shares the same design as any other minifig, but he's made of some strange matter, capable of radically altering his size, and if shattered or smashed will just pull himself back together in no short order.
- Made of Evil: Exactly what Vortech is made isn't clear, but one piece of it is enough to fuel the Tri, and it's pretty dangerous to be near.
- Master of Disguise: He disguises himself quite a number of times over the course of the game.
- Omnicidal Maniac: He wants to combine all universes into a single, "perfect" one.
- Orcus on His Throne: Vortech spends a lot of the game sitting on his throne, only directly attacking the heroes twice, at Hill Valley and then in Scooby Doo's world. It's justified, since the means he used to find Foundation Prime have apparently taken a toll on him, and occasionally cause him to lose control of his own body.
- Original Generation: As with X-PO, Lord Vortech is a new character created for this crossover game.
- Pulling Themselves Together: He spends much of the fight in Hill Valley doing this.
