Tokageroh

Tokagero(トカゲロウ Tokagerō) is a fictional character in the anime and manga series Shaman King, and is the guardian ghost of Umemiya Ryunosuke, nicknamed "Wooden Sword" Ryu

About
Tokagero is a 600 year old spirit from the same time as Amidamaru. He was a thief who was eventually killed by Amidamaru and because he wanted revenge he was not able to pass on. Because of his hatred he eventually turned his skin lizard green. During his life time he became infamous even gaining his own fighting style called Tokage Kenpo(Lizard Style) He always calls himself a nasty villain but is in reality a big softie who only misses the comfort of a mothers care.

Past
He was born on November 14, 1374. When he was alive, Tokagero was a thief that was born into poverty. Tokagero was forced to eat his own dead mother to survive. He then became a thief ambushing people. An Ancient Brigade! He stole everything--money, food, lives! He led a horde of bandits who terrorized the area 600 years ago!

There was a hill Tokagero and his group used as a hideout, but one day Amidamaru killed him and his group, at the age of 35.

Present Time
In the modern age Tokagero attacks Yoh Asakura and his friends in order to get revenge on Amidamaru, who does not recall him at all. Through Anna Kyoyama's research, they learn that he is an obscure historical figure who was killed by Amidamaru. Tokagero possesses Yoh's friend Ryunosuke Unemiya ("Wooden Sword" Ryu) and uses him to steal the Harusame (Sword of Light) from the museum and attack Yoh and Amidamaru. The fight that ensues forces Yoh and Amidamaru to break the Harusame in order to save Ryu's life.

Yoh appeals to Tokagero and allows him to possess him instead of Ryu, who is just an innocent bystander, because Yoh believes that Tokagero is not as evil as he claims. Togakero does so, with the supposed intention of killing Yoh in the process, but finds he does not have the heart to and leaves Yoh's body peacefully.

Shaman Fights
It was then Tokagero prepared to move on, but for some reason he still could not enter nirvana and eventually decided to becomes the spirit ally of Ryu. It was during this time that Ryo wanted to train with Yohmei Asakura who had trained Yoh when he was young. But he declined saying that the Shaman Tournament was to dangerous for an unskilled man like Ryu. However after agreeing in the mountains of Izumo Ryu became stronger and Tokagero embodies the spirit of the mythical river god called "Yamata no Orochi"

Later after training with Anna under the Shaman Tournament, Tokageroh evolves into a Seirei(holy)-class spirit and gains a complete new form as the Yamata No Orochi.

O.S. Tokagero-Bokutō
O.S. "Tokagero-Bokutō"(O.S.木刀にトカゲロウ) Description: This is Ryu's first Over Soul, made by integrating Tokagero's ghost with his bokutō. This O.S. provides Ryu with much needed protection in the form of shoulder armor and prehensile, snake-like tendrils that are used to bind enemies as well as defend against attacks. Originally, this O.S. manifested as armor, turning Tokagero into a shield bearing his likeness, before being re-imagined. Overall, this O.S. proved to be Ryu's most versatile O.S. type, if not the weakest. Ryu even created a 'legendary hitch-hiking' technique revolving around this OS called his "Jumbo Thumb Over Soul" creating a huge 'green thumb' with a striking resemblance to Tokagero's face.
 * Shaman: Umemiya Ryunosuke
 * O.S. Type: Spirit Type
 * Spirit Ally: Tokagero (human ghost)
 * Medium used: Bokutō, carved from normal wood

Attacks


 * Hell Dragon Crimson Lizard: A simple downwards slash with the oversoul cutting something in half.


 * Hell Dragon Scarlet Lizard: A cross slash with oversoul that cuts up an opponent


 * Yamata No Orochi(ヤマタノオロチ): By manifesting the river spirit into Tokageroh, Tokageroh grows long snakes out of his hair and will eventually use this for an attack. It creates a large white spirit ball around the Bokutō and sprouds the heads of the Yamata No Orochi that can then crush any opponent with a spear like thrust attack of its head.

O.S. Yamata No Orochi Go
O.S. "Yamato No Orochi Go" (O.S.ヤマタノオロチ号) Description: The result of Anna's training. Thanks to her training, Ryu learned to harness, at will, the power he displayed during his fight with Boris, the vampire shaman. Orochi provides all the advantages of the previous form, but in the form of an 8-headed serpent, yielding far greater ferocity and power. Once a seirei-class spirit, this evolved O.S. transforms Tokagero into the fearsome “Yamata-no-Orochi Go”, a gigantic O.S. which places Tokagero as the rider of a humongous, 4-wheeled motorcycle monstrosity with 8 humongous serpents heads, looming over an oversized replica of Tokagero's headguard. This O.S. variation, aside from its naturally high defenses, is surprisingly mobile.
 * Shaman: Umemiya Ryunosuke
 * O.S. Type: Spirit Type
 * Spirit Ally: Tokagero (seirei-class)
 * Medium used: "Ame-no-Murakumo" bokutō, carved from shin-boku--holy wood

Attacks


 * Super Attack(Chariot Attack): This attack involves using the the multiple heads of the O.S. to grab and crush any object.

O.S. Sushi Knife Susanoro
O.S. "Sashimi Bouchou Susanorō" (O.S.刺身包丁スサノロウ) Description: In order to compete against "The Ren" Team, the Funbari Onsen Team began training to hone their shamanic powers, and Ryu developed this O.S. as a result. It's an Armor-type O.S. made from integrating Tokagero's ghost with Ryu's Ame-no-Murakumo bokutō. The O.S. takes the form of a giant sushi knife with Tokagero's signature headguard visible over the hilt, and shoulder armor created over Ryu's right arm. This O.S. embodies Ryu's dream of becoming a sushi chef, which makes this O.S. all the more powerful. He was supposed to show this O.S. of in the fight against Team "The Ren" however Horohoro quickly shattered his hands and made it impossible for him to fight. Instead it was first revealed in the first Plant of the Dessert where he fought against Namari and his animal spirit Red Rope. Susanaro comes from the name of the hero who slayed the "Yamata No Orochi"
 * Shaman: Umemiya Ryunosuke
