What?
For me it was a boss called The Orphan Of Kos and it's move set was so hard to read and understand and the damage was insane, it's quick, annoying, loud and don't even get me started on stage 2we all have fought those bosses
For me it is viper from titanfall 2. He pilots a titan that uses a sniper rail cannon, flies around non stop, and shoots a s*** ton of rockets occasionally. Nuff said
LolExpert skeletron.
Really a hardmode boss.
Come on.
