I don't know if anyone has notice this but Zygarde and the new Large Mouth ultra beast look similar

Zs body: Thin and sleek, it's chest has a pattern on it that looks like a mouth, it also has two huge glowing areas that look like eyes on its chest

UBS body: Larger, fatter and bulkier body, has a literally mouth filled with teeth yet it has the same pattern on zygardes chest but located above the mouth under the yellow patching.

Zs wings: Zygarde has four prominent sets of wings, thin and long that are ample to open up at each end

UBS appendages: has four massive appendages making up claws and arms, has two large spikes near its head sticking up like zygardes wings

Zs head: a narrow smooth head that created a crown, very humanoid like along with white glowing eyes

UBS head: similar to zygardes head it has a humanoid head with glowing blue eyes however it's crown line appearance is more jagged

Thats all I have for now, tell me if you see the similarities or not
