Oh my gosh.
Someone posted a list of phobia headcanons for the 9 cast,
and it totally reminded me of how 1 had this MASSIVE Catskull phobia in the first big 9 RP I participated in
even if they were on the “good” side, he’d panic if they came near him.
The culmination of that particular plot point was him violently smashing and killing one the main characters — a Catskull — when he became Fab-1.
