Wither Skeleton

The Wither Skeleton is a mob Encountered in the nether

Trivia
1. Despite being as tall as Endermen, they can still walk past 2-block high tunnels without getting blocked off, but they can still suffocate.

2. If you manages to hypnotize them, their attacks won't add Wither Effects to Mobs (bug?)

3. If a Spider Jockey and Wither Skeleton was seen in a level, there is a chance that a Wither Jockey will spawn instead.
