My OCs fear:
Azure - fear of losing CJ
Siral - hurting his friends
Kial - broken heart
Callis - losing hope
Neon - losing his friends
Casper - betrayal
Cloud - extreme hights
Accarix - remembering his terrible past and what he done
Pastel - the resets from his timeline
Outcode - being alone
Ivis - the mysterious person that took his sister
I do have a lot, but this is so far of what most of my OCs fear is
