Invictus Potens (40k)

assault cannon, storm bolter, power fist, and centuries of combat knowledge

Sword Brother Adelar was a renowned adeptus astartes with great skill with the blade quickly earning him title of Sword Brother, he died and was revived as a dreadnought, the process unknown to him after her got beat to near death and knocked unconscious from an Ork using dirty tactics

a Venetable dreadnought armor pattern that has been service for many thousands of years and it's really starting to show its age, it has had many dying astartes in it's life support coffin before and they have all died in combat but Invictus Potens lives to fight again and again

the pilot will slowly go mad and insane, dreadnought can be deactivated for up to hundreds of years, in that time many friends they used to know will die in service and they could've done nothing to help them they are only awaken for combat which is their specialty and release the only constant in their degrading life cycle of death and war

he is eternally grateful for the opportunity to serve even after death, he's slowly going mad in his tomb of a machine knowing death will come for him again and this time there will be no second chances, he tries to hide his feelings by bestowing combat knowledge on those who serve with him but he doesn't know how much is left of his real body, whenever he moves a limb only metal and machine respond

half of his skull is missing with life supporting implants all over what's left of his body, all his limb were brutally torn and only most of his right arm remains as he floats in the life support liquids inside the sarcophagous, most of his teeth is missing and he no longer has a tounge, his voice hooked up to a speaker on the dreadnought, he doesn't know any extent of his injuries
