This piece was done by the ever-talented (and slightly evil) geckonori!
So apparently, sojiroex decided he wanted to do a little spar with his teammate, Lucas. One use of Minimize later, and this battle goes about exactly as you'd expect.
A Stomp to take off a good chunk of HP, a frying pan to get the burn status to weaken him a bit further, and some chomping and swallowing takes off the last of it. Good think Lucas has unlimited respawning!
