The daughter of the legendary warrior Aramus, and possibly the most adorable human child alive. She begins the series trying to protect a strange box she received from her father from a pack of werewolf assassins who killed her caretakers. The box contains her father's magic gloves, that grant superhuman strength and invincibility. When she's forced to put them on, even she's able to beat up building-sized demons with ease. But still, the gloves may be too big for her figuratively as well as literally.
- Badass Adorable: Gully is the most adorable child in the series. She can also kick some ass, and is more than willing to take as much of a bruising as she gives to do the right thing.
- Berserk Button: Throughout the entire series, Gully firmly and angrily insists that her Disappeared Dad is still alive to anyone who implies otherwise. The first thing she does after donning Aramus's gloves is beat the main Lycelot who had been hunting her to death while demanding to know what happened to her father.
- Cute Bruiser: She's an adorable child that can beat up demons with ease.
- Disappeared Dad: Aramus disappeared under mysterious circumstances shortly before the series began, after raising Gully as a single parent.
- Everyone's Baby Sister: Garrison, Calibretto, and Knolan have all placed her under their protection.
- Girlish Pigtails: Promotional art for the original comic consistently portrayed her wearing this hairstyle, but she never used it in the story itself. Nightwar finally gave up and used her hairstyle from the main storyline.
- Missing Mom: As part of his Hannibal Lecture to Gully in issue 9, Sebastius Nefar asks if Gully ever knew her mother. Shortly afterward, while brooding, Gully remembers how her father told her that her pendant belonged to her mother — even though Sebastius' flashback repeatedly features an identical pendant.
- Nigh Invulnerable: Aramus' gauntlets also protect her from harm. Her Establishing Character Moment in Nightwar establishes her as the party's tank.
- Power Fists: She uses giant magical gauntlets that give her ridiculous strength and durability.
A master warrior and swordsman, who wields a powerful mystic sword a la Excalibur that can cut through anything. Although he was a living legend among the ranks of the Marshal Paladins, he begins the story as a drunken wreck mourning the death of his bride-to-be. Nevertheless, he starts down the path to take up his sword again after learning that the daughter of his mentor, Aramus, has vanished...
- Dating Catwoman: Although he and Red Monika were never in a relationship during the series, they clearly had some Unresolved Sexual Tension and enough of a bond for Garrison to refuse to hunt her down. A backup story in the last published issue (drawn by Adam Warren) showed Monika persuading him to swear never to let the Marshal Paladins hurt her.
- Heroic BSoD: Garrison spent the first few issues depressed over the death of his wife-to-be.
- I Will Fight No More Forever: Garrison promised Vionna, his wife-to-be, to lay down his sword. Not even learning that Gully had been kidnapped was enough to make him break that vow (he plays Technical Pacifist and Guile Hero to come to the rescue without a sword). The Maestro of the Marshal Paladins finally gives him a What The Hell Hero Speech that makes him realize that he has to come out of 'retirement'.
- Knight In Sour Armor: Garrison begins the story as a drunken wreck, leading to his cynicism. Even after he sobers up, it's clear that he's seen, done, and gone through too much to be optimistic.
- The Mourning After: The death of his wife-to-be, Vionna, turned him into a drunken recluse, almost unrecognizable to those who knew him before. He never completely moves on from her death, even after having broken his promise to her by taking up his sword again.
- Tranquil Fury: Although everyone who knows Garrison is wary of an Unstoppable Rage within him, he remains stoic and controlled, even when an enemy (such as Brass Demur from the attack on Capital City) is deliberately provoking him.
An old "War Golem", effectively a massive walking Magitek weapons platform filled with cargo bays worth of kill-stuff. Also a "pacifist", and nature lover, who was staying in hiding with Knolan before rescuing Gully from her pursuers in the first issue.
- Become a Real Boy: Expresses a desire to know love after Gully explains the concept to him.
- Gentle Giant: Calibretto, despite his appearance, is a "pacifist" (when he tries to be) and nature lover.
- Grew Beyond Their Programming: Knolan believes he has, since he's perfectly willing to lay down his life for Gully. Knolan explains that a single War Golem is worth a hundred soldiers, thus it should've gone against his programming to save Gully, who is only a small girl.
- Last of His Kind: The War Golems were built to fight in the Great Offscreen War; after winning, King Vaneer decreed that the remaining golems were to be destroyed. Calibretto found sanctuary with Knolan.
- Nature-Loving Robot: Often has birds perching on him. In Nightwar, his victory pose has a flock of birds landing on his shoulder. He's also shown covered in birds during the intro. His healing skills are also all nature themed.
- Papa Wolf: To Gully. Not even being deactivated will stop him from protecting her.
An ancient, powerful, insufferably sarcastic wizard who can manipulate the elements. He was a member of an older party of adventurers whose past was coming back to haunt them. Near the "end" of the series, it was implied he was running low on time.
- Deadpan Snarker: Knolan is a insufferably sarcastic old man in addition to being a powerful wizard.
A young, voluptuous female rogue and leader of a band of airship pirates. She accidentally sets off a massive jailbreak and an international incident while trying to free a minor criminal from the local Alcatraz. Apparently Garrison's
lover Unlucky Childhood Friend, who still has a bond with him although they're on opposite sides of the law. Never a member of the main party during the original comic book run, but still a major character. And of course, she's two of the main reasons people read and remember this series.
- Adaptational Modesty: Monika's infamous bust has been toned down by a few cup sizes in Battle Chasers: Nightwar, though this seems to be more for technical reasons than outright bowdlerization. Despite this, she remains the most well-endowed character in the game and her starting outfit is actually a bit more daring than the comic book version.
- Boobs-and-Butt Pose: She takes this pose in one of the variant covers of the first issue.
- Fiery Redhead: Monika is swift to release her fury against friend and foe alike.
- Guns Akimbo: Her Weapons Of Choice in Nightwar are dual revolvers.
- Knife Nut: She also wields knives, frequently poisoned. A one-shot side story from the original series revolves around her stealing her knife from a death cult while she was a child.
- The Lad-ette: Red Monika is a tall, leggy, extremely well-endowed, beer-drinkin', hard-livin' air pirate.
- Ms. Fanservice: The series plays up her sexiness a lot. A good portion of her panels have her breasts or backside prominently displayed and a number the covers for issues are pinups of her.
- Poisoned Weapons: Many of her abilities and bursts in Nightwar depend on using poisoned knives or bombs to debuff enemies.
- Terrible Trio: Red Monika and her two sidekicks, Bengus and Akiman.
- Throw Down the Bomblet: Nightwar has Monika using small bombs as grenades to debuff enemies (or to remove debuffs from the party). Her ultimate Limit Break is a bomblet.
- Unwitting Instigator of Doom: The raid on Skyhold that she thought would go smoothly enough to use as therapy for her old friend, Garrison? Not only does it cause an accident that frees several other prisoners who go on to attack Capital City just to draw Garrison out (drawing the rest of the main characters together), but her client was the Greater-Scope Villain, who almost kills her. Finally, because the jailbreak became an international incident, King Vaneer sent the Marshal Paladins against both her and Garrison (who refused the job of either bringing her in or killing her).
A new character introduced in Nightwar to join the original cast. Alumon is a member of a mysterious order of devil hunters native to the Crescent Isles, where the game takes place.
- Creepy Good: He is firmly on the heroes' side, but has his fair share of creepiness going on, from his appearance and abilities, to his constantly keeping an eye on Garrison.
- Luckily, My Shield Will Protect Me: Alumon's Weapon of Choice is a shield; he attacks with a sword, but players need to find, craft, or purchase new shields through the game.
- Sixth Ranger: He joins the party a third of the way through the game.
- Reasonable Authority Figure: Or Pragmatic Villainy. Vaneer is cynical, clearly ruthless, and possibly corrupt, and he is also the reason that Calibretto had to go into hiding with Knolan. However, despite this, he ultimately welcomed the main characters after they saved his capital from the attacking prisoners, and never betrayed them before the series' last issue.
- Bald, Black Leader Guy: The leader of the Marshall Paladins, reporting directly to King Vaneer.
Residents of Harm's Way
- Arms Dealer: Grimbeard is the NPC who sells weapons and armor, along with crafting recipe books for both.
- The Blacksmith: He forges the weapons and armor he sells; if the play spends enough to upgrade his shop, he'll even let you borrow his forge.
- Nubile Savage: Raha is a Cat Girl in a Fur Bikini who sells the crafting materials left by enemies, meaning she does plenty of hunting.
- Quest Giver: She offers players rewards for fighting Bonus Bosses throughout the game, and provides hints about what each character needs to do to unlock their ultimate Limit Break.
- Sexy Mentor: Trains the characters on how to perform Burst attacks.
