Shalba Beelzebub

Shalba Beelzebub was a member of the Khaos Brigade's Old Satan Faction. He is the descendant of Beelzebub.

Personality
Shalba was cruel, evil, and manipulative. He manipulated Diodora Astaroth into working for the Old Satan Faction and killed him when Diodora lost his usefulness. Like Creuserey Asmodeus and Katerea Leviathan, Shalba believes that he is the true ruler of the Underworld, calling himself a "True" Satan. After his defeat by Issei in Juggernaut Drive, Shalba went insane, planning to destroy all Devils and the entire Underworld for denying him.

History
He and the other descendants of the Satans (except Vali) believe that the current Devil system is mistaken and seeks to change it by killing the current Satans and taking control of the Underworld.

Plot
Shalba first appears in Volume 6, killing Diodora Astaroth who begs him to kill Issei. He then sends Asia to the Dimensional Gap and told the Gremory Team that Asia is dead. This action, however, turns out to be his undoing as he accidentally made Issei activate his Juggernaut Drive as Issei goes berserk biting off his left hand, overwhelming Shalba who was beaten to near death because of it.

In Volume 11, Shalba reappears with a kidnapped Leonardo, forcefully activating the boy's Balance Breaker which creates 13 gigantic monsters, which he uses to attack the Underworld in an attempt to destroy all the Devils that rejected him. He then kidnaps Ophis and escaped into the crumbling dimension with Issei chasing them. He eventually fought against Issei but was defeated and killed by him but manages to use an arrow infused with Samael's blood which caused Issei's apparent death.

Powers & Abilities
As the descendant of the Satan Beelzebub, Shalba has a impressive amount of demonic energy. When using Ophis' snake, his demonic energy is equivalent to the previous Beelzebub. During his second fight with Issei, he reveals the ability to control bees.

In his first appearance, Shalba wielded a device that appeared to allow him to control light similar to the abilities of an Angel or Fallen Angel.

Trivia

 * Shalba is the only descendant of the original Satans aside from Vali to appear more than once.
