With season three of Marvel’s Daredevil set to premiere on October 19, the Netflix series has truly pulled out all of the stops. After dropping a whole building on Matt Murdock’s head at the end of Defenders, it looks like the Devil of Hell’s Kitchen has come to a realization during this third season: the only way to fight evil is by being evil. It doesn’t help when series big bad Wilson Fisk ups the ante by introducing a new villain, Benjamin Poindexter, aka Agent Dex, aka Bullseye, to the series.

For fans of the Daredevil comic book series, Bullseye being introduced is a welcome surprise. He’s been one of Daredevil’s adversaries, and one of the few foes who can stand toe-to-toe with the lawyer-turnt-hero. His backstory is shrouded in mystery, but that’s where we come in. For those of you who might not know who the hell Bullseye is, or just need a refresher on why he’s such a threat, we’ve got a quick look at everything you need to know about Bullseye before you start binging season 3 of Marvel’s Daredevil.
