Biography: The third modern human member of the Green Lantern Corps., John Stewart is a former Marine whose discipline and seriousness shows in his approach to being a superhero. A talented architect, Stewart "builds" his constructs from the inside out, making them stronger and more durable.
Intro: John Stewart flies in while charging his ring on his lantern, and holds up his fist, with his ring shining brightly, saying "You don't want to do this."
Post-Round Taunt: Creates a green aura around himself and says "Had enough?" or "You can't win."
Outro: Projects images of the Guardians of the Universe around him, saying "I'm done here. What's next?" Afterward, he stands with his arms crossed as the Guardians circle around him
* Assault Rifle - Shoots three rounds quickly with an assault rifle construct
** Meter Burn - Shoots three more rounds even more quickly after the first three
* Marine Sniper - Gets down on one knee and shoots forward with a sniper rifle construct, hitting low and causing large knockback
** Meter Burn - Shoots the opponent with a pistol construct as they fly through the air after being hit with the sniper
* Beatdown - Creates a giant fist around his own, slamming it downward, making the opponent hit the ground and bounce upward to allow for juggling
** Meter Burn - Once the opponent bounces into the air, John kicks them away
* Eruption - Uses his ring to create a circle underneath his opponent, which eventually erupts into a damaging beam of light that extends upward; however, it is not immediate so the opponent has time to escape
** Meter Burn - Once the light fires upward, he directs it back downwards to do double the damage
* Chain of Command - Shoots forward a link of large chain that wrap around the opponent if they connect, trapping them for a limited amount of time
* Green Lantern's Light - Bursts out a bright green light from his body in all directions, blinding an opponent if they are close enough and allowing him to retreat to a farther distance
Launcher: Flies forward to knock opponents away
Forward - Binds opponent using a construct, then shoots them forward using a large blast of light
Back - Binds opponent using a construct, then flies behind them and shoots them forward using a large blast of light
Shielding - Creates a projectile-proof force field around his body, allowing him to deflect projectiles for a limited amount of time
Architect's Imagination - John flies forward to grab the opponent, and, if it connects, flies them into space, where he constructs a large platform that the opponent stands on and then a detailed city around them; after this, he uses his ring to make a large Godzilla-like monster that runs through the city, destroying it; the building topple onto the opponent one-after-the-other, and ultimately the monster grabs the opponent and throws them back down to Earth
Ending: Always the dutiful one, John Stewart originally went along with his friend Superman's plans for a Regime that would unite the world and end crime. However, he grew uneasy as Superman's methods became darker and his Regime became more oppressive. The final straw was when John's friend Hal Jordan gave in to the power of fear and joined the Sinestro Corps. Seeing that the Regime matches the ideology he had fought against as a Green Lantern, John Stewart defected from the Regime and is now one of Superman's most powerful enemies.
