Seeing Pulsefire Ezreal's interactions got me thinking, imagine having an animated series based on Pulsefire Ezreal's adventure through different timelines while Pulsefire Caitlyn chases him! So much potential can be made with the skins as animated series. I know PROJECT and Star Guardian are also great candidates for animated series, but seeing PF Ezreal jump through different universes in each episode would be so hyped. We'd never know what universe he'll go next till the last scene on an episode and I'd think that would be cool as.
We'd also discover bits and pieces of story in each Universe too and I'd love to see more of the smaller universes as of now like Eternum and Wardens vs Marauders.
