I'm pretty sure flamebaiting is against the RULES, Brian!
Closest thing to that is really his own personal Dark Tower in Gobbotopia City (or his backup tower near the other Hobgoblin City at worst).I suppose Xykon really doesn't have a base of power, but if he did, that's where he should be destroyed.
…and is at his weakest, yes. Technically, he only ever meant to set foot in there again if his current body was destroyed!
