OC-dropping - Putting an OC in a story like they were born to be there and

Putting an OC in a story like they were born to be there and everyone else is just a footnote

My OC was in the original Star Wars and no one noticed until now.

I added my OC to a fantasy novel and now they’re the reason the dragons are mad.

My OC showed up in the middle of a history test and changed the whole timeline.
