Hi, everyone what is your least favorite enemy(s)?

Mine are the wardens, especially on higher difficulty setting.

Mine was the grunt holding the birthday party skull.
Too hilarious to kill.

I hate all the Forerunner enemies. Part of it is to do with how 343 designed their aesthetic (all 343 Forerunner design, not just the enemies). I hated them in Halo 4 too. Pain in the -Yoink- to kill some of them without completely emptying your weapon, especially on harder difficulties.
