Personally, it’s Faith from Farcry 5 for me. Uninteresting dialog that can be summed up to “I was bullied once” and that’s it. Literally every other character is so much more interesting. Jacob gives you a sequence where you run through a gulag which he then uses against you, John tries to kill you and is openly hateful towards you plus is a character you get to interact with, and Joseph is a lunatic who was right.
Tatsu from Xenoblade Chronicles X is a really annoying little dude. I watched my buddy play through and every time he said anything he’d tell the tv “shut up Tatsu.” It’s arguably more aggravating because the game seems aware of his annoyance since one of the main characters is constantly suggesting she cook him into a dish to eat. I’d say that would be the best outcome.
You stay away from my tatsu!
