Daredevil Season 3: 10 Things You Need To Know About Bullseye
6. He Has An Obsessive Personality
It took less than a few run-ins with Daredevil before The Man Without Mercy developed an unhealthy obsession with The Man Without Fear, as he tended to do with everyone he was assigned to kill, or was just in the mood to target.
Daredevil and Bullseye's long running feud was like an even nastier, more blood-spattered version of Batman and Joker. Bullseye made Daredevil his flavor of the month, which was heightened by the fact that Daredevil had deliberately tarnished his career as an assassin. Lester would exploit any available opportunity to force an encounter with him, including one where he orchestrated a fight on live TV.
The obsession was made worse when Bullseye developed a brain tumor, which caused his already unhinged mind to mentally shape-shift any bystander into a Daredevil facsimile, who he would then kill.
On a marginally lighter note, Bullseye went through a stage of donning the red costume and playing the part of Daredevil during Murdock's absence from New York. This caused Murdock to return and undergo a full cos-swap, battling Bullseye dressed as er... Bullseye, and ultimately defeating him.
