Meta Cooler: (having just regenerated an arm) Perhaps I should have explained earlier? My body is constantly monitored by the Big Gette Star's main computer. Any injury I might suffer is instantly detected and repaired - and whatever flaws in my design that allowed the injury are corrected. It's quite remarkable, really. In simple terms, of course, this means you can't win.
Goku: (grimly) I'll just have to try harder.
Cooler: By all means, try.
