This article is about a/an Imagin in Kamen Rider Decade.

The Alligator Imagin (アリゲーターイマジン Arigētā Imajin), based on the story of The Fox and the Crocodile (キツネとワニ Kitsune to Wani), is an Imagin who enacts his own scheme to change the past and is able to emit energy waves from his arms.

Unlike other Imagin, the Alligator Imagin goes through a multitude of hosts to enact his scheme. Arriving in the past on December 30, 2008 via a child, the Alligator Imagin proceeds to change the future and overpowers Decade and Den-O, taking the latter's DenGasher as his own.

Diend and his KamenRide Card summoned Riotroopers allow for Den-O and Decade to regroup, and allow for Decade to get the Den-O Cards. With both Kuuga and Den-O, Decade destroys the Alligator Imagin with the Den-O Final Attack Ride.
