|This article is about a/an monster in Kamen Rider Drive.|
Arimammoth had appeared during the third timeloop, backing up Cheetahkatatsumuri and Hiruchameleon, fighting against Drive, who had egged the Inhumanoids to attack him. When Go and Kiriko arrived after hearing the commotion, Arimammoth began charging up a energy attack and flung it at Go. Desperate to save Go, Shinnosuke transformed into Type Speed and rushed to go, taking the attacks for Go and dying as a result. In the final loop he was impaled by Zeronos ZeroGasher Sabre Mode and destroyed when it's Full Charge attack was loaded.
Powers and Abilities
He is armed with a pair of tusks on his neck that are ideal for goring and can fire energy balls from them as well as use his neck trunk as a whip.
- Along with the Cheetahkatatsumuri, they are the only two yellow-boots monsters who has the Shocker Belt.
- Being the combination of mammoth and ant, Arimammoth's existance is ironic, since both mammoths and ants had great distances in their different body dimensions.
