Mark/Invincibles little brother, Omni-man/Nolans son, half Phlaxan half Viltrumite, lives on earth with mark and their mom Debbie, funny, kinda annoying, heart of a soldier, only 13 years old, little brother energy, idolizes invincible and Omni-man, potential to be a great hero, has a bit of a crush on Zoe/tech jacket but good friends with her

Omni-man, father to Invincible/Mark Grayson and Omni-kid/Oliver Grayson, serious, not a lot of emotion but there, warrior, turned back on viltrum, hated on earth, trouble between him and his son mark, a little bit of trouble between him and his son Oliver, one of the strongest viltrumites

Leader of the Coalition of Planets, hates the viltrumites, funny and sarcastic and all round cool dude, good friends with Nolan, powerful, hero where he’s from, good friends with tech jacket, owns the ship they’re flying on

Tech Jacket, funny, cool, almost like a girl iron man, 13 years old, good friends with Oliver Grayson but not sure if she has feelings for him or not, good friends with Allen the Alien, 2nd Tech Jacket after her brother Zachery/the original Tech Jacket passed away

Hungers for more glory and battle, his name is literal, no emotion besides rage, probably the strongest warrior in the universe besides Grand Regent Thragg, probably only decided to join the Coalition of Planets to kill Viltrumites and that’s probably also the reason he hasn’t killed the others with him, fought mark once and almost killed him, tagged along Allen to save Nolan from a Viltrumite prison, hungers for more

Not much known about him but has a gun that shoots bullets that penetrates through everything no matter one it is. It goes straight through. And rides an extremely fast space bike. Doesn’t talk much, Oliver wants to ride his bike and shoot his gun

Grand Regent of the Viltrum empire, hates the coalition of planets, killed Thaddeus/ex leader of the coalition of planets, the most powerful being in the universe besides Battle Beast

Most loyal and dangerous viltrumite, destroys worlds and probably the one they’ll send to earth if the Coalition of Planets lose, emotionally broken, already fought Mark once on earth the first time he came to conquer the planet, scares his own kind

General of the Viltrum empire, Thraggs right hand man, dangerously smart, commands the soldiers, really good fighter

Viltrumite soldier, powerful, beef with Nolan who Killed his sister Thura
