You know how in some games they sometimes put a few regular enemies with boosted stats in a room and call it a boss fight? That's N.
He was raised by and grew up with animals and can talk to them? Has to learn how too live with humans now? Man oh man, never heard that one beforel. Like god damn, that was in Gilgamesh, literally the single oldest story in recorded history. It's been done sooo much, by sooo many storytellers a lot more competent than Gamefreak.
And his whole motivation, good lord. "Hey man, we capture wild animals and make them fight eachother, you ever think that's messed up?" Yes, N, we do, all the time, we have discussed that to death, you're like 15 years too late.
So his gameplay sucks, his backstory sucks, his motivation sucks, his story sucks, N sucks. Sorry buddy, maybe you could have been good, but you weren't, at all.
