Looks like someone at Riot really likes Supergiant Games because it looks like they took aspects of both Transistor and Bastion and put them into 1 character.

I think the real problem here is that his design is pretty generic, it looks really solid and has a good silhouette (looks a little like wukong) but the design itself is overwhelmingly generic.
Ekko would fit RIGHT IN as a DLC character for Borderlands 2
Yeah I still see more of the cell shaded art style of Borderlands than anything else in him. Rito is known to reference a lot of other games/stories/ideas with their character concepts so it doesn't surprise me. Ekko still is very unique but he draws on a lot of cool nostalgic references to make him even better.
I'm compelled to narrate everything that I do with him in a baritone voice.
"The Kid's in trouble, his enemy is relentless in his movements, and bloodthirsty in his attacks. At any other circumstance, that'd be it for him, but lucky for the Kid, he's got his Time Machine. Gonna fix all the problems in the world, just him and his little gizmo."
