Excer is the leader of Excer Org and the living incarnation of Uthrasel.
Excer is the mysterious leader of Excer Org, or Excer Organization. Excer is the mortal incarnation of Uthrasel and leads a large group of followers who fight various injustices. The current Excer himself is revealed to be a man from Pretoria, Africa with a knowledge of black magic (Likely due to him being an incarnation of Uthrasel).
The name Excer itself is simply a title and those that hold it are always incarnations of Uthrasel, however sometimes other members have assumed the name Excer on several occasions when a real Excer is absent for prolonged periods of time.
Many Kekeroos revere Excer and are also members of Excer Org.
