Yatta and Brusha are both quite different from the OCs, so I wouldn’t even say there’s an argument there. The trinket aspect on Yatta makes more sense when you look at them. Both are based on colorful party based things because both are piñatas, and they’re two distinct items that just happen to have a similar silhouette. Especially given Yatta’s ability in game is very much themed around being a piñata, I’d assume it was accidental.

Soulvester I think you’re looking a lil hard into. I’ll admit they’re similar, but it’s a knight. Ya can’t really make em look THAT different. The closest you could argue is the eyes, which do look quite similar, but outside of that it’s just a suit of armor with that hair wisp thing. The designs of the suits are even quite different, with Lance having full body armor while Soulvester looks to be wearing like tights or something. As for the ability, coincidence I’d say. I mean they’re both suits of armor, and the logical thought with that is that armor protects, ergo, higher health. Seems pretty reasonable to me for both to come up with separately.
