In ROGUE-00's chest is a glowing core of infinite dimensional energy. The core is its energy, and it uses the energy to travel through universes. If its defeated and damaged, then it will use this energy to travel back to wherever it came from to repair itself. If completely deactivated in a fight, an emergency protocol activates, and activates a portal that sucks in whats left of it. This core apparently gives ROGUE-00 minor regenerative abilities.
One of the intimidating things about ROGUE-00 is its single, red eye. It can scan just about everything in sight, and can gain info on any threat just by one scan. Also, somehow, if you were to stab it in the eye, it can still fight as if it can still see you. Stabbing it in the head period won't do much good either, but chopping it's head off will definitely render it defeated. Good luck with that though, since its metal of unknown origin is stupidly strong.
Another intimidating thing is that its very tall. If its arms look freakishly long, believe me, they're supposed to be that way. He also has claws on his fingers.
ROGUE-00 has a jetpack for flight and transportation. Somehow, it has infinite fuel. Maybe it gets its power from the core.
On both of ROGUE-00's arms are two "Pylons". They carry its weaponry. Its adaptable to any situation. It usually has either a laser blaster, or a blade come from it, but it can be anything.
One thing that you should have noticed: ROGUE-00 is not colored. He is one of my OC's, but I have no idea how his coloring should be. He's actually one of my more recent OC's. Nonetheless, he will have color. Just stay tuned.
