|This article is about a/an rider in Kamen Rider Decade.|
Zanki (ザンキ) is Zaomaru Zaitsuhara's incarnation from Kamen Rider Decade.
He has the ability to transform into Kamen Rider Zanki (仮面ライダー斬鬼 Kamen Raidā Zanki), who is master of the guitar-based Ongekidō Zanki Style (斬鬼流 Zanki Ryū), stationed at a dojo. He is Ibuki's rival and thus their schools are sworn enemies. Zanki and his entirely male student body wear karate gi; Zanki's gi is black and he wears a black haori over it. After being convinced by his student to give the idea of allying the three schools a chance, he steps down as mentor in favor of Todoroki. He later joins the fight without his "mask" against the Bakegani, wielding his Retsuzan.
- Rider Height: 6 shaku 9 sun (approx. 209.1 cm, one say 210 cm)
- Rider Weight: 43 kan (approx. 161.3 kg, one say 161 kg)
In this form, Zanki is a bronze demon that looks like Todoroki. To become this form, Zanki 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. Zanki also gains a second "oni face" which is a crest that forms on his forehead. Unlike most Kamen Riders, Zanki does not wear a suit, rather his demon form is his true form.
- Henshin Kigen - Onka: A bracelet-like transformation device.
- Ongekishin - Zantetsu: A device that attaches on his belt for uses of finisher attacks.
- Disk Animals: Zanki's disk-like support robots.
- Ongekishingen - Retsuzan: A guitar-like weapon.
- Kitōjutsu - Raigekiken (鬼闘術・雷撃拳 Demon Fighting Technique: Lightning Strike Fist): Charging himself with power, Zanki does an electric-powered punch that paralyzes all organs of any Makamou he is in battle with.
- Kitōjutsu - Onizume (鬼闘術・鬼爪 Demon Fighting Technique: Demon Claw): Forms claws from his hands to stab and slash at Makamou.
Ongeki Zan: Raiden Zanshin (音撃斬・雷電斬震 Sound Attack Slash: Thunderbolt Slash-Quake): Zanki stabs his weapon into the body of a large Makamou and changes is into its guitar form. He begins playing the guitar as fast as he can, causing electricity to flow from his body into the body of the Makamou, slowly causing its organs to expand and eventually explode.
Behind the scenes
Zanki (A.R. World) is portrayed by Kenji Matsuda (松田 賢二 Matsuda Kenji).
- Unlike the original Zanki, this Zanki seemed in good condition, so he didn't have Weakened Zanki statistics and his statistics remains normal.
