Magneto but he has a dissasociative disorder smiles big and wide. Something like DDNOS-1a or OSDD-1a where he isn't a system persae [OSDD SYSTEMS EXIST IM NOT SAYING THEY DON'T] but he still has some personality fragmentation. He atleast denies being labelled a system.
He has a facet that holds trauma and a facet that holds rage. A facet that makes sure he keeps himself alive, stuff like that. Not Alters, but more different hims that he remembers.
Would also explain how Erik flip flops in his different itterations on if he's chill or not [Example: Rivals vs MCU/Fox]. Also explains why Erik is so reactive but not to the point he is always triggered.
