What is a unit in your gacha game that completely outclasses most/all units with a similar niche or usage

For battle cats. it's talanted sanzo. He has 4 while niches and absolutely destroys them. Slow and weaken towards angel and floating. Funniest part is he's only a rare. And yes although due to how Battle Cats' works the best units are rares / super rares. This guy still stands out due to the sheer amount of outclassing he does
