Cuttledeep (カトルディープ Katorudīpu), nicknamed Mongo (モンゴ), is one of the many Beastformers who joined the insurgent army under Alligatron raised by Galvatron in order to aid his Decepticons in conquering the formerly-peaceful planet Beast. He enjoys a good challenge, being very tenacious and growing more fired up the tougher something is. His capability for high-speed underwater movement even in the deep ocean netted him the position of deep sea disruption soldier in the Decepticon-allied Beastformer army, but his true talent lies in engineering, particularly when it comes to thinking up theories and designs. One of his creations is his personal weapon, the Dream Spear, which can project holograms underwater to fool enemies. Cuttledeep holds the rank of Emperor of North Yutoranta, under King Polar Battle Bear, and was born in Bug Bay.
