Most gens have something redeeming about them, but there is less and less every time. In the latest i can only think of a single good Pokemon and a good megaman character that somehow found its way into the game.

You are probably thinking loudred, which was gen 3, but that seemed like a fine-ish background mon imo. Not great, not something I'd use on my team certainly, but not fundamentally bad. Ya know?

Space, time and antimatter gods were actually in gen 4, and their design was decent even if their lore was jumping the shark so hard. We've had gods of dreams and truth, gods of life and death and environmentalism, extra dimensional aliens (and aliens we feed our aliens to), and a time traveling dinosaur and robot pair. Legendaries are turning into Digimon and usually not good ones at that.
