This article is about a/an rider form used by several identities in the Kamen Rider Series.

Kamen Rider Leangle

Kamen Rider Leangle may refer to any the following characters.


The Leangle system was developed Isaka, the Peacock Undead, who needed the sealed Spider Undead to complete it. However, it was later revealed that the Undead was not sealed properly and manipulated his users for his own agenda.

Ace Form

Ace Form

"Open Up!"
―Transformation announcement[src]
  • Height: 205 cm[1]
  • Weight: 111 kg[1]

Ability Parameters

  • Punching Power: 300 AP (3 t.)[1]
  • Kicking Power: 490 AP (4.9 t.)[1]
  • Maximum Jump Height: 30 m.[1]
  • Maximum Running Speed: 100 m. per 5 sec.[1]

Ace Form (エースフォーム Ēsu Fōmu) is the default form of Kamen Rider Leangle assumed by using the Leangle Buckle and Change Spider Rouse Card. The transformation fuses the user with the DNA of the Spider Undead. Leangle's Ace form has higher ability parameters than Blade and Garren, allowing him to compensate for the fact that he cannot assume other forms like them.

Jack Form

Jack Form

"Absorb Queen: Fusion Jack!!"
―Transformation announcement[src]
  • Height: 205 cm
  • Weight: 131 kg

Ability Perimeters

  • Punching Power:, 370 AP (3.7 t.)
  • Kicking Power: 580 AP (5.8 t.)
  • Maximum Jump Height: 25 m.
  • Maximum Running Speed: 100 m. per 6 sec.

While never assumed in the series, Leangle's Jack Form (ジャックフォーム Jakku Fōmu) can be seen in the manga and S.I.C. toyline. Leangle would theoretically assume this form by inserting the Absorb Tiger Rouse Card into the Rouse Absorber and scanning the Fusion Elephant Rouse Card. Unlike other Jack Forms, this form is not as maneuverable and lacks ability to fly, compensates with superior strength and defensive abilities.

King Form

King Form

"Absorb Queen: Evolution King!"
―Transformation announcement[src]
  • Height: ?
  • Weight: ?

Ability Perimeters

  • Punching Power: ?
  • Kicking Power: ?
  • Maximum Jump Height: ?
  • Maximum Running Speed: ?

Similar to Garren's King Form, Leangle's King Form (キングフォーム Kingu Fōmu) is not shown in any of the shows except for the S.I.C. toy line and manga. This form is accessed through the ♣Q: Absorb Tiger and ♣K: Evolution Tarantula cards. Leangle's helmet is now modeled after a tarantula with all the sealed Category Club Undead cards decorating the armor plates.--->

Evolution Tarantula

Tarantula Undead

The Evolution Tarantula (エボルーショントランチュラ Evorushon Toranchura) is the result of the sealed Hikaru Jō and Noboru Shima seizing control of Leangle from the Spider Undead after it attempted to transform into King Form with Garren's Rouse Absorber. In the ensuing battle against the Spider Undead, who was expelled from Mutsuki's body, Mutsuki morphed between his human form and Shima's Undead form. This form, along with Blade's assistance, allowed Mutsuki to defeat the Spider Undead and properly seal it.
