Doctor Octopus is Born
Doc Ock attacked Wayne Tower, over his personal grudge against Bruce Wayne. He broke in and started wreaking havoc. He was unbeatable, and when he finally killed someone, Batman and Robin showed up and fought him. They fell out of Wayne Tower, but Otto saved himself and got away.
After facing several defeats from Batman, Doc Ock teams up with the Joker. The two of them managed to kidnap Batman and Joker wanted to kill him, but Doc Ock wanted to make him suffer. This led to an argument between the two and they fought. Joker threw Doc Ock into a wall containing Joker venom prototypes. It burned Otto's skin and he was forced to be put in a suit that kept him alive.
