@royal Yeah, love Vanisher, especially in the old Fallen Angels series.
@prototart It must've been at the same place. They let you app old FCs and keep their +traits (which saved a lot of time and hassle). Thought it was a neat character choice, lots of great hooks.
@the-tree-of-woe I stayed pretty well out of the way of the drama (and the X-sphere), so I didn't even know you were hated.
I remember Night Thrasher was hated, but he just seemed like an enthusiastic kid to me (who maybe missed some of the subtleties of MUXing).
God, do you remember when we had huge New Warriors and MLF teams that were clashing nearly daily? The Night Thrasher player advocated this really proactive 'we must organize as a team to stop all villains on-grid', where if any New Warrior ran into a villain ICly, they'd jump on the New Warriors channel and summon ten friends. Meanwhile, the Stryfe player basically organized daily mass murder sprees in New York, so you'd end up with these massive 20+ person scenes of total havok.
Kind of a shitshow, but they were obviously just kids having fun.

@the-tree-of-woe That's teenage life in a nutshell.

What's out there right now that actually has an active playerbase? Preferably canon Marvel or DC.
