>>23513147Kang doesn't Mega, the baby does. That's how they explained this one.
>>23513153>>23513170Dumb, yes. Makes sense? Also yes. The shell and Slowpoke basically become one single life form. Like a coral reef, and how a lot of the reef is made up of lots of different animals that functions as a single unit as if it was one creature. So the Shell has grown to protect the fleshy body of the Slowbro that feeds it sustenance.
Only problem is that Mega Evolution isn't meant to be possible in the wild, so why would a Mega Evolution make biological sense?
