read FMA and have become fully fascinated by Van Hohenheim. Genuinely has there ever been a better immortal character. His combination of invulnerability & low self esteem means he has about zero self-preservation instinct and will just let people knock him flat including his own 15 year old son.
His entire deal is that he became superpowerful by convincing 500000 ghosts to talk about their feelings but he's too nervous to talk to his own two sons because he thinks they don't like him. Which to be fair, they do not. but cmon dude.
