Main characters

Zenkaigers

The eponymous Zenkaigers consist of a lone human who leads a team of four Machine Life Form Kikainoids from the parallel world of Kikaitopia. 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 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 team finisher is the Zenkai Finish Buster. When enlarged, the robot members can access stronger, mecha-like forms via Kikai Transformation and summon a giant version of the Geartlinger called the Geartlinger Bazooka to perform a stronger version of the Zenkai Finish Buster.

Kaito Goshikida

Kaito Goshikida is the leader and sole human member of the team. He is a cheerful young man who is usually easygoing, but dedicates himself wholeheartedly when something piques his interest. Prior to the series, his scientist parents discovered parallel worlds before they suddenly disappeared, leaving Kaito to be raised by his grandmother.

Using the Zenryoku Zenkai Cannon rifle, Kaito can summon copies of past Super Sentai members to fight alongside him and perform the Zenryoku Zenkai Finale Buster finisher, though the finisher itself produces such tremendous recoil that it requires the rest of the team to brace him in place and prevent him from flying off upon pulling the trigger. It can also enlarge and transform into the Zenryoku Eagle fighter aircraft, which can perform the Zenryoku Kaizer Storm finisher.

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 Donbrothers to initiate Avatar Changes into past Sentai warriors.
Furthermore, Stacaesar possesses dark copies of the Sentai Gears called Dark Sentai Gears, which he can use to create copies of past Super Sentai teams 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.

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.

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.
