Overwatch Game Director Jeff Kaplan recently sat down with the team at IGN to check out some of the history behind the game’s characters. Admittedly, not all of the stories are particularly exciting (Hanzo’s ultimate used to be called the caterpillar because that’s what it looked like before the team finished the final animation), but there are interesting tidbits here for anyone interested in how Overwatch was created.

The video series is broken down by tank, defense, offense, and support heroes. Check them all out below.
