Molecule Man isn't more powerful than Living Tribunal, nor is he uneffected by LT. IMO, the origins of his powers still doesn't make him immune to LT's jurisdiction. His powers is still below that of Tribunal, Eternity, etc. Molecule Man, Beyonder, Kubik, etc. are parts of a cosmic cube. And we all know that five or six cubes was still not enough to satisfy Magus, who wanted the power of the Infinity Gauntlet instead. If we're talking about Pre-reconned Beyonder, then yes LT isn't more powerful. If it's the True Beyonders, they are either less than, equal to, or above LT in power it's unknown. Molecule Man still only have a small portion of their powers. And no, Magneto can't kill Molecule Man - it's the other way around.
Though he comes from Earth, I'd rate him as a cosmic level being. Franklin is a mutant, but the exposure to the Power Rod and the fact that the origin of his mother's power on the same wave length as that of the Celestials and acquire from being exposed to cosmic radiation make Franklin a unique case. Yes he's a mutant, but abnormal from the rest. X-Man, however, is clearly and potentially the most powerful mutant.
Magneto is one of the most powerful mutant. And we are talking about raw power right? Doom, Iron Man, etc. don't count. It could make you powerful, but at hand who's more powerful. As for Apocalypse, what's he done to put him at planetary level powers? Tech aside, what can Apocalypse himself do? Don't know much about Gravy to judge.
