I'm at work so not looking in depth, but from what I remember while reading over the sheets they all look good. Hesitent on the character lifting 50 tons, though, as he could probably throw around a stack of 3 or 4 spacefighters with ease, or cars weigh even less so around 15 cars, which seems like huge overkill. He's probably stronger at breaking down doors than explosive charges would be. If I allow him to keep that strength than to use it, all of his muscles might burst.
