4. Requim (Karthus)

If you play League of Legends even just a little you would know that Karthus would be on this list. Karthus was an incredibly weird dude with a creepy obsession with death. He embraced undeath and became a litch and now revels in his loving relationship with the grave. He is one creepy dude.

Karthus’s ult has a channeling duration for a few seconds during which most enemy players just sit back and accept their fate. Karthus targets all opposing champions and hits them with a powerful nuke. The ability can’t miss and can only be avoided with the help of an item like Zhonyas. What is worse is the fact that Karthus can cast this after death.
