Bron is one of ten Patch Officials/ Priests; he is Lyserg's officiant.
Not much is revealed about his past.
Bron is created by Hiroyuki Takei; he has no information regarding any inspiration used to create him. It's assumed that Bron's name is based on the metal, Boron, since his name means Boron in Japanese. He first appears in Shaman King volume 24: Chapter 208.
Bron waits for Lyserg and his gang in the wind valley. As soon as Horohoro and Ren open the door, Bron kills both of them instantly. Both Ren and Horohoro are revived to fight Bron. In their battle, Bron binds everyone into a spider net except Lyserg who knows Bron's moves due to their first meeting in the Shaman King preliminaries. Lyserg eventually kills Bron by burning his body.
Bron's spirit is Bluenet, a spider spirit. His spirit mediums are his cuffs on his wrists and ankles which are made of spider hair. Bron's Over Soul is the thin web (his prey sometimes do not see it) he uses to bind his prey; he uses his web to fire at his enemies.
