I'd probably disagree, in terms of Marvel's Thor he would sit somewhere around T-7/8 so certainly in high powered, but not god tier.

Gods in this tier system are gods in a very literal sense of being able to do -anything- pretty much.

For reference sake, my character Kaelin is T9 using the old system, in that his only constraint is pretty much that he has a finite amount of energy (though in his case, it is the energy of an entire solar system, star and all.) He would be considered High powered (right on the upper edge) but not god tier.
