Mephias is a video game exclusive character. He was The Guardian of Demons who became Shaman King hundreds of years ago. Mephias had three guardian ghosts whose names are unknown. He only created chaos as the Shaman King. He is most likely more powerful than Zeke. Mephias appears in Shaman King: Master of Spirits as the final boss, and reappears in Shaman King: Master of Spirits 2 as a secret boss.
In his first form, Mephias wears a black cloak that covers his whole body except his head. He attacks with his three spirits in ball form. He also attacks with a flail hidden in his robe.
After damaging him enough, Mephias removes his robe. In this form he wears a white robe that covers his legs. He also creates three oversouls with his spirits: a red pata on his left arm, a blue, snake-like dragon head on right arm, and green insect wings on his back. The dragon oversoul's medium is his flail, but the other mediums used are unknown.
Abilities and Powers
- Flail Attack: Mephias shoots his flail out of his robe, changing its direction in midair to home in on Yoh, then slamming it into the ground.
- Red Spirit In his first form, Mephias shoots his red spirit towards Yoh and inflicts fire damage. In his second form, Mephias uses dark energy to enter the ground, follows Yoh, then leaps out and slams the ground with his red oversoul, launching rocks into the air.
- Blue Spirit: In his first form, Mephias moves his blue spirit across the top of the arena, shooting projectiles in all directions when it reaches Yoh. In his second form, Mephias shoots three fireballs from the dragon head that drop to the ground and explode. The dragon head can also dart out and bite Yoh.
- Green Spirit: In his first form, Mephias uses his green spirit to shoot a ray that paralyzes Yoh, then attacks with his red spirit. In his second form, Mephias creates an insect wing oversoul with his green spirit and does not attack with it.
- Web Attack: Mephias cancels his oversouls and creates a giant spiderweb. Small flames travel along the strands of the web, damaging Yoh on contact.
Mephias has three spirits: a red one, a blue one, and a green one. Their names are unknown.
Mephias became the Shaman King hundreds of years ago, creating chaos with his powers before being sealed away.
The shaman Magister wanted to exact revenge on Yoh because his ancestors were killed by the Asakura clan, so he summoned Mephias. However, Mephias did not obey Magister and Yoh defeated him.
