What champ do you hate the most?

THE YETI KNOWS THE WAY.

Fighting against? Thresh. There's very little counterplay to being crowd controlled over and over and over again, and that lantern. In a team fight, even if you're God at prediction to stay out of trouble yourself, well you have a mess of teammates that probably won't be so lucky. Thresh is an ass.

Fighting with? Tristana. Feels like more often than not they die leaping in for no real reason. Repeatedly. Admittedly this seems to be happening less as my elo increases, but I still have memories that make me check opgg every time.

Vladimir No mana poke under tower without punishment made me tear my hair out more than once.

Given a kit to fulfill her fantasy, at the cost of game health, also pretentious people are my most hated kind of people.

and I hate them both soooo much

Stupid personality, stupid kit, stupid lore and stupid players.

Then again my opinion is pretty stupid so...

Xerath. Uninteractive laning phase, then always gets fed because he does too much damage from too far away, even if you went even with him. You have to go through his entire team to kill him, meanwhile he just proceeds to murder everyone.
