Badamon is the ruler of all Nether Spirits. He was summoned by Talpa
for two reasons. The first was so that Talpa could instruct his
warlords on the Inferno Armor and how to capture it. The second
was for the building and activation of the 9 shrines that would
link the Human and Nether realms.
Badamon acted only in the background, never actually engaging in
battle. He instructed the Warlords and advised Talpa. Badamon later
possessed Lady Kayura after the amulet which kept her under Talpa's
control was destroyed.
Badamon has knowledge of all of the ancient legends. He knows all
of the powerful spells, the power to possess people and control
all of the Nether Spirits. Badamon possesses enhanced versions of
all of the powers of the Nether Spirits
