I am Jury-Rig (Wo)Man. Every time you damage one of my goon-bots, I grab debris from objects you’ve destroyed on my level to repair them. The way to beat me is by avoiding all of my minions and sneezing Mega-bot Flu into my face. I don’t technically die, but I’m bedridden for two weeks, so you can just take my stuff.
The power Mega Woman derives from beating my level is Transmog Tape: use it on yourself to return some of your life, on a fallen adversary to create a shitty minion, or on destructible terrain to make power-ups. But when you run out of Jury-Rig energy, you have to call a contractor. The contractor may/not condescend to you.
