Gumball is the main protagonist of the comic. He has "the power of optimism," which is activated by the glowing heart on his chest. He has an incredibly muscular build, due to Chuck Klein's How to Draw Superheroes book that simply says "draw muscles, then more muscles." His sidekick is the Smooch (Darwin), his girlfriend is Sarah, and his arch-nemesis is Onyx.
The Smooch is LaserHeart's one and only sidekick. He isn't as ripped as LaserHeart. His power is to kiss people and make them feel better. Not that much is known about him, except for his powers.
Sarah is the creator of the comics, and a character inside the comic series. She appears to have a romantic relationship with LaserHeart, and mentions him and his brother fighting over her affection. She has no powers, which is ironic considering she's the writer of the comic.
Based on a thief who stole Gumball's wallet, he is an antagonist who has the appearance of a black humanoid with grey hair and red eyes. At one point during a battle with LaserHeart, he stole his heart and shattered it but was quickly defeated when the Smooch gave LaserHeart his powers back.
- "The Drama" (arcade game, cameo)
- 62 issues of the comic have been made, each being based off the misadventures of Gumball and Darwin.
- The characters are a reference to DC superheroes Batman and Robin.
- LaserHeart bears a strong resemblance to the superhero Pureheart The Powerful from Super Teens by Archie Comics.
