Mar'jik can, during bouts of intense meditation, use Level 3 for Mind Reading. However he is in no condition to fight or even defend before or after that. It's actually not useful for much, come to think of it, except maybe for lie detection.
Then not approved. You can only get level 3 powers by being level 3, you can't will yourself into evolving up then devolve back down when you get tired. And, as I said, I really don't like someone trying to declare they have a power level they haven't earned yet
Flash, on the other hand, is fine
