A lot of it has to do with ‘what feels right’ for the character. What fits their personality, etc, but it’s largely just the whims of the Animator working on that hero, haha. Yrel’s dance, for example, is a combination of a video I found on the interwebs, and my personal go-to move on the dancefloor.
Many heroes will date themselves with their dances or taunts, which I kind of revel in. If there is a pop culture reference that is rather viral at the time, the animator sometimes draws inspiration from that. I animated Junkrat’s dance in the heat of that trend. He wasn’t released until 6 months later, or something - unfortunately outliving the fame of the moves, themselves.
Thank you! I will!
