Mammoth Dinozord is the Dinozord of Ice piloted by Zack Taylor (Black Ranger). He was originally known as Mastodon Dinozord in Mighty Morphin Power Rangers. As Alvin uses the Iceglisten Gem to summon him, Simon joins in the battlefield.
Mammoth Dinozord's heart of pure light allowed him to be preserved in the form of the Iceglisten Gem. Queen Elsa has been keeping the Iceglisten hidden in her Ice Palace until Alvin finds its for Simon.
When Mammoth Dinozord is summoned with the power of ice, he emerges from a glacier in Arendelle. He can blow glacial gas called Mammoth Blizzard (モスブリザード, Mosu Burizado, "Moth Blizzard") of -200°C from his trunk to freeze his enemies.
