I think somebody once made a thing where the person was exactly what people thought of them. So like, if they thought they were a beast of incredible strength, they were, but if they thought they were a dumb rat. Well. They were. But they had no control over what they were, it always depended on other people's thoughts. Could be cool if you got a person to think you were a giant monster, then everybody thought you were, so you were most often a giant monster. Then somebody thinks otherwise and BAM you're screwed I mean maybe it could be where they neeeeed to keep it a secret from their opponents etc etc. Could be kinda. You did say weird super powers. Thas weird. ALSO, IF NOT ALREADY SAID. A person who manipulates gravity. He can only change the gravity of one person at a time. Its harder to use on others, easy to use on himself. Eh?
