Gabarus Giberious Heliostom (ガバルス・ギベリウス・ヘリオストム) is a character in the anime and manga series Battle Spirits Shounen Gekiha Dan
He has very tall blue hair and a beard, and black eyes. He wears a green shirt and pants, under a long purple and gold top, with a belt. He has gold armor on his shoulders, and a gold crown. Also, he has large green wings and elf-like ears.
Heliotsom is very prideful and arrogant. He hates humans, and acts very controlling towards his son.
Heliostom is a mazoku. He is the father of Brustom and husband of Ryoko. Their family is unstable though, as he and Ryoko have been fighting for thousands of years, and Brustom left to live as a king to the humans, something Heliostom highly disapproved of.
As he was a friend of Namii's, she had he and Brustom battle against Dan and Clackey, when they came to her castle to find Mai. During the battle, Heliostom tried to control all of Brustom's moves, and then only defend his own spirits. They lost the battle, and Heliostom decided to let the castle walls absorb him. However, Brustom saved him.
He uses white.
