Name two things you hate fighting

Name two things you hate fighting.
Bonus points if the two can be combined together into one terrible opponent.

Gelatinous Cube Red Half-Dragons

Any enemy that splits into more enemies when damaged.

Strictly RPGs or other tabletops are allowed as well?

I really hate fighting Quachil Uttaus in Arkham Horror.

I'm actually curious if any of the Kingdom Death Monsters are particularly hate-worthy.

Gelatinous Rust Cubes

The screaming antelope exists to trick you into fighting it early, then it eats your gear and since you split your fights between two monsters you don't have enough resources to make anything good before the butcher TPKs you.

Well some players I know hate anything that can damage or destroy their weapons, armour, and other items. They also hate anything that doesn't target AC to deal damage. Great when used occasionally to remind them there is more to a character than gear and yes death is a possibility.

As a player I never liked orcs as they usually were used as dull chunks of hp with no tactics or thought, taking to much time to kill. I have some other bugbears but those outside the scope of this thread.

That's right around what I expected, except I expected just a little more rape.
