Ingvar Brandt is a brown Mewtwo that traveled through eldritch dimensions and fought Lovecraftian horrors that lie beyond.

Mostly quiet compared to Roy Knight. His time being within the Lovecraftian realms caused him to become ageless and gained a resilience to explosions, giving birth to his use of Rocket Jumping, he even Market Gardens with a mean-looking blood-stained axe.

He a wields a rocket launcher and a minigun that modified into a Super Nailgun. He is also responsible for harnessing Slipgate technology that the FPS Guild uses for navigation and weaponry
