List of Kikai Sentai Zenkaiger characters

Kikai Sentai Zenkaiger (機界戦隊ゼンカイジャー) is a Japanese tokusatsu series that serves as the 45th installment in the Super Sentai franchise and the second entry in the Reiwa era. Some of the characters also participate in Zenkaiger's direct sequel, Avataro Sentai Donbrothers.

Zenkaigers
The eponymous Zenkaigers consist of a lone human who leads a team of four Machine Life Form Kikainoids (機械生命体キカイノイド) from the parallel world of Kikaitopia (キカイトピア). Later in the series, the team receives assistance from the World Pirates' leader, Zocks, in their fight against Tozitend's regime and the fugitive Stacy once their fight is nearing to a close.

The Zenkaigers utilize a multipurpose Geartlinger (ギアトリンガー) firearm for transformation, combat, or to enlarge the robot members of the team. It can also access the weapons and/or abilities of past Super Sentai heroes by scanning a Sentai Gear. Their finisher is the Zenkai Finish Buster (ゼンカイフィニッシュバスター). When enlarged, the robot members can access stronger, mecha-like forms via Kikai Transformation (機界変形) and summon a giant version of the Geartlinger called the Geartlinger Bazooka (ギアトリンガーバズーカ) to perform a stronger version of the Zenkai Finish Buster.

Sentai Gears
The Sentai Gears (センタイギア) are a series of gear-like items that the Zenkaigers use to access their powers. Aside from their personal transformation gears, they also possess legend gears that unlock the powers of the other Super Sentai, numbered after their respective season and usually stored in either Zenkaizer's Zenkai Buckle (ゼンカイバックル) or Twokaizer's Twokai Buckle (ツーカイバックル). The Zenkaigers use abilities pertaining to the original members of each Sentai team while Twokaizer gains powers based on their additional heroes. During the final battle against Bokkowaus, the Zenkaigers' personal Sentai Gears turn into Avataro Gear-shaped Sentai Gears. In Avataro Sentai Donbrothers, the Sentai Gears are also used as part of the alternate Kaito's equipment, some of which are obtained from the destruction of a Hitotsuki. By obtaining a Sentai/Avataro Gear from the destroyed monsters, the alternate Kaito is able to share its powers with the rest of the Donbrothers to initiate Avatar Changes into past Sentai warriors.

Furthermore, Stacaesar possesses dark copies of the Sentai Gears called Dark Sentai Gears (ダークセンタイギア), which he can use to create copies of past Super Sentai members and/or mecha to fight for him. However, according to Izirude, the Dark Sentai Gears must be used sparingly or else said copies will disappear from overuse. Staceasar later gains an upgrade that allows him to summon upgraded copies of the Sentai members based on their powered-up forms.

After Stacy falls out of Tozitend's favor and Mitsuko escapes from their palace, Izirude brainwashes and transforms Isao into the crimson-colored "Machine Power" (機械のパワー), Hakaizer (ハカイザー), so he can serve as Tozitend's second enforcer. Hakaizer battles the Zenkaigers on several occasions before Kaito eventually succeeds in freeing Isao from Tozitend's control. Following this, Isao researches the World Pirates' technology, modifies a car so it can travel through the multiverse, and departs to look for Mitsuko, eventually finding her in Sushitopia and bringing her back home.

Goldtsuiker Family
The Goldtsuiker Family are Zocks' siblings who, like him, were inspired by stories of the Gokaigers to become World Pirates and support him in his quest to find the SD Toziru Gear.

Flint Goldtsuiker
Flint Goldtsuiker (フリント・ゴールドツイカー) is Zocks' younger sister. She is well-versed in gear technology, having created the Geardlinger through reverse-engineering of Tozitend's equipment while replicating the Zenkaigers' Sentai Gears for Zocks' own use.

During the events of the stage show ''Zenkai!! Twokai!? Need for Development!! G-Rosso Last Fight!!'', Flint is able to transform into the silver-colored "Invention Power" (発明のパワー), Twokai Flint (ツーカイフリント).

During the events of the web-exclusive special Twokaizer × Gokaiger: The Tanuki-Charmed June Bride, Flint utilizes Gai Ikari's Gokai Cellular in conjunction with the Twokaizer Ranger Key, which was temporarily created from the Twokaizer Sentai Gear, to transform into Twokaizer.

Flint Goldtsuiker is portrayed by Hinami Mori (森 日菜美). As a child, Flint is portrayed by Hinano Amaya (雨谷 日菜乃).

Twokai Cutanner and Twokai Ricky
Cutanner Goldtsuiker (カッタナー・ゴールドツイカー) and Ricky Goldtsuiker (リッキー・ゴールドツイカー) are Zocks and Flint's younger twin brothers. They were turned into small robots, with Cutanner becoming the red-colored Twokai Cutanner (ツーカイカッタナー) and Ricky becoming the blue-colored Twokai Ricky (ツーカイリッキー), by a curse from the parallel world of SDtopia (SDトピア). After SDtopia was sealed within a Toziru Gear, Cutanner and Ricky accompany their siblings in their quest to find it. Both can fuse with Twokaizer to give him extra abilities, and like the Kikainoid Zenkaigers, they can be enlarged by their brother to assist him in battle. Following Kaito's victory over God, Flint devises a way for them to freely alternate between their human and SD forms.

Twokai Cutanner and Twokai Ricky are voiced by Ryōta Suzuki (鈴木 崚汰) and Satsumi Matsuda (松田 颯水), respectively. In their original forms, Cutanner and Ricky are portrayed by Kōsei Sutō (須東 煌世).

God
A mysterious entity who claims to be God and the creator of the multiverse. Believing he had too many worlds to care for, he possesses Gege to manipulate Tozitend into sealing them for him and bring them under his control. Amidst this, he later takes an interest in Stacy, possessing his body to meet the Zenkaigers while displaying his ability to release or destroy parallel worlds contained in the Toziru Gears. He helps the Zenkaigers destroy Tozitend before possessing Kaito and sealing all of the dimensions. But Kaito breaks free and eventually defeats God in a Rock Paper Scissors match, with the being accepting his loss and allows Kaito to unseal the worlds.
