EXO consists of twelve members.

The group was originally separated into two sub groups -EXO-K and EXO-M- but now all 12 promote as one group instead of 6 in each group. EXO-K is the Korean group and EXO-M is the Mandarin group; so there is always a Korean and Chinese version to their songs.A few of their songs include WOLF, XOXO, HISTORY,  GROWL and MAMA along with many others.

The members’ stage names are (K) Baekhyun, Sehun, Chanyeol, Kai, Suho- (leader) and D.O. (M) Luhan, Tao, Kris- (leader), Lay, Chen, Xiumin.

The name Exo came from the term Exo Planet- which is a planet outside our solar system- their entertainment company SM Entertainment chose a unique and creative way to introduce the group as people from another planet so in turn the members all have special ‘powers’; such as light, wind, flame, teleportation, Water and Earth as well as telekinesis, time control, flight, healing, lightning and frost.
