As nice as it is that we can kill Prof using unlimited materials and a lot of time, we should probably be looking for something a little easier to manage. Dropping him into the ocean would probably keep him down for a long time, but that's borderline impossible to pull off, even for a flying Epic, since it all but requires you to choose the stadium and have tons of time to plan things out. Is there any way to handle Prof that doesn't involve a crazy amount of time, resources, and preparation? Wouldn't it just be easier to use a large explosion and then chop him into pieces once you pound through the shield? It's been shown to run out, so then it's just Healing Factor, which can be overcome with slicing and dicing. I guess what I'm saying is, we should probably limit ourselves to practicality. Overkill is still nice, but practicality trumps.
