Tomizo Todayama

Kamen Rider Todoroki (仮面ライダー轟鬼) is one of the many Oni Kamen Riders in the Kamen Rider Series Kamen Rider Hibiki. He solely goes by the name Todoroki (トドロキ) and abandoned his human name Tomizo Todayama (戸田山 登巳蔵) upon becoming an Oni.

History
He is the last Oni to join the main cast of the show. Despite that he is the second oldest Oni of the core three at 28, he is still very much a novice. A green Oni, both in color and appearance, he is still learning how the world around him works. Having only just become an independent Oni during his introduction, he sticks close to Hibiki and Ibuki and looks to them for guidance. Eager to do please his master but do things in his own style, he often meets conflicting points of views from others, but continues on with what he believes is "his" way. Todoroki was the last of the main series' Oni to be introduced. He was first seen in episode 14 greeting Asumu at a hospital. He later returned with his master, Zanki, to fend off a pair of Makamou. Originally he was to be the next Zanki, but declined the offer from his master so that he could create his own legacy as Todoroki.

Of the three main Oni, Todoroki is the second oldest, yet he is the most childish. He still acts like a novice with many Oni matters and enjoys the simple things that life has to offer him. He is also one of the more clumsy characters on the show, this trait often leads to problems both in and out of battle. Even though often misguided, Todoroki will stand by his friends no matter what comes their way.

When he became a solo Oni, Zanki had some trouble accepting the way that he fought the Oni and his "cleansing" of the battlefield. Eventually Zanki came to accept that this was Todoroki's way of being an Oni. During the summer of training arc, Todoroki saw Hibiki as a teacher, and Hibiki offered Todoroki guidance on being a solo Oni and the new challenges that life would bring him now that he had no master.

Todoroki soon came to find fighting the Oni on his own to be a tough challenge. In response to this, Zanki returned to be his supporter and offer advice whenever he could.

Throughout the series, Todoroki had a crush on Hinaka Tachibana. One day he gathers enough courage to asks her out on a date on her birthday. The date goes horribly wrong for Todoroki, he makes a fool of himself and ruins her gift. Hinaka became upset with Todoroki and the two were distant with each other for a while.

Late in the series after the Shuki incident, Todoroki was literally stepped on by a giant Makamou. This left the others questioning whether or not Todoroki would ever be able to transform again. Zanki feared this would cause Todoroki to go into a state of depression, indeed it does. Zanki believes that Todoroki was born to be an Oni and that he knows no other way of life.

Eventually Zanki meets his end, but puts a spell on his soul to allow him to remain on earth until Todoroki no longer needs him. It was around this time that Hinaka and Todoroki became friends again, even though she offered her help to teach him how to walk again, Todoroki declined. Even when Zanki helped him out, Todoroki said he wanted to do it on his own, otherwise he would never be able to show that he is an independent warrior.

Todoroki learns to walk again and rushes into Zanki's final battle, the both make quick work of a large number of Makamou and soon it is time for Zanki to pass on. Todoroki and Zanki have one final cleansing session as Todoroki pays his final respects to his former master. After these events, Todoroki has finally become the man that he always wanted to be.

Many fans agree that Todoroki was the most changed character of the entire series. Going from a new Oni, still worried about his skills and unsure about his ability to live in the world on his own to a confident man who works well with others and trusts in his own strength.

OOO, Den-O, All Riders: Let's Go Kamen Riders
Kamen Rider Todoroki was part of a group of reinforcement riders led by Akira Date/Kamen Rider Birth to aid the primary riders in defeating the Rock Great Leader. All the Kamen Riders got on their bikes and performed the All Rider Break attack which destroyed the Great Leader.

Oni Form
Ability Perimeters:
 * Rider Height:Todoroki.jpg 212cm
 * Rider Weight: 157 kg.
 * Punching Power: 30 t.
 * Kicking Power: 40 t.
 * Maximum Jump Height: 69 m.
 * Maximum Running Speed: 100 m. per 5 sec.

In this form, Todoroki is a green demon. This is his basic form and the easiest form for him to reach. To become this form, Todoroki simply needs to pluck his brace strings, the vibrations from the strings cause his body to be hit by massive lightning bolts, changing him into his Oni form. Todokori also gains a second "oni face" which is a crest that forms on his forehead. Unlike most Kamen Riders, Todoroki does not wear a suit; rather, his demon form is his true form.

Henshin Kigen Onjō

 * Device Type: Wrist Brace
 * Other Forms: None

Unlike the other Oni's henshin items carried on their belt, this is worn on Todoroki's left arm like a bracelet. The Henshin Kigen - Onjō (変身鬼弦・音錠) is worn on the wrist, plucking the small chords sends out special sound waves which gives Todoroki the ability to transform into an Oni. After plucking the cords he places it in front of his forehead forming an Oni face. He raises his arm into the air as lightning strikes him with electricity surrounding him while he transforms. In addition, the Onjō can also playback the sound or video data collected by the Disc Animals.

Ongekishin Raigō
Ongekishin - Raigō (音撃震・雷轟): Todoroki attaches this to his weapon to turn it into a guitar for his Ongeki Zan Raiden Gekishin.

Ongekigen Retsurai
Ongekigen - Retsurai (音撃弦・烈雷): Todoroki's Ongeki Weapon is the Ongekigen Retsurai. Taking the Retsurai's "blade attacking mode" along with the Ongekishin Raigou, forms the Retsurai's "guitar mode". Plugging the end of the Retsurai into the Makamou, Todoroki utilizes Sound of Purification by playing his guitar, the pure sound waves destroy the Makamou.

Ongekibō Rakurai & Ongekiko
Ongekibō - Rakurai (音撃棒・落雷) & Ongekiko (音撃鼓): A pair of drum sticks formerly owned by Zanki, Todoroki uses these when he had to fight Dorotabou, a summer Makamou that can only be defeated with drum-type Ongeki.

Attacks

 * Kitōjutsu - Raigekiken (鬼闘術・雷撃拳) Charging himself with power, Todoroki is able to directly attack any Makamou with electricity. He can do this through a punch or kick.
 * Kitōjutsu - Onizume (鬼闘術・鬼爪) Forms claws from his hands to stab and slash at Makamou. These claws are nearly unbreakable, thus making them one of Todoroki's most useful weapons.

OnGeki Finishers
Ongeki Zan - Raiden Gekishin (音撃斬・雷電激震) Todoroki stabs his weapon into the body of a large Makamou and changes it into its guitar form. He plays the guitar in a wild and fast manner. By doing this, the vibrations of his weapon are directly transmitted to all the organs of the Makamou, causing it to explode.

Support Vehicles
Raijin (雷神) Make: HONDA Element

Disc Animals
Produced mainly for reconnaissance purpose, the Disk Animals (ディスクアニマル) or Onshikigami (音式神) are shikigami on compact discs instead of paper. They can switch between their animal forms and disk forms like origami, and can turn invisible at will. The following are the disc animals that Todoroki uses.


 * Celadon Frog (青磁蛙): It can function best underwater where it is able to travel up to speeds of nearly mach 1.
 * Green Ape (緑大猿): This disk animal has the special function of video recording images and sound because its intelligence is a little higher than normal. It's acrobatic and suited for through branches in forested areas. It's very strong and delivers a power punch for attack, because of this it can also guard and protect victims from danger.
 * Madder Hawk (茜鷹): The falcon is light weight and suited for covering terrain from the air. With its sharp wings it is capable of cutting attacks in both of its forms. Its weak point is both its duty and recording time is cut short from the energy it consumes from flight.
 * Azure Wolf (瑠璃狼): With its four-legged design, it is best for ground terrain, especially dense brush and rock areas. When sent out in numbers they usually travel in packs. It has a sharp, fanged mouth for attacking targets. Has a long duty and recording time and is very durable.
