Right now I'm gonna vote for Digi.
I think his 10x for Zod's armor, as well as his speed, makes Kinky much better defended than normal, as well as basically amping Apollo x10 becasue of the sunlight. I mean, seriously. The armor normally takes punches from Superman pretty easily. So if you took Superman x10, the new and improved armor would logically be easily strong enough to stand up to a barrage from even-more-super-Superman. This plus the insane strength boost would make Kinky the best brawler here... By a lot.
For KVD, Loki's a damn good magician, probly pretty even against Mordred. So I think this fight will come down to fisticuffs, which I already explained my logic behind.
Sentry is just relying way too much on the nega bands, which are damn hard to use. Insane or not, druid's not doing a whole lot with them.
Stormfront is relying totally on Zatanna being able to master Storm's power very very quickly. Loki being able to negate someone tampering with his body wouldn't surprise me at all anyway. I'm thinking this also comes down to victory by smashed in skull.
