D-Stroy

is a Rank S Merican Yo-kai of the Slippery tribe.

The Yo-kai Medallium bio reads; "Dinoshi grew up, and now dramatically smashes things to rubble with his overwhelming super-strength. The D is for 'Destruction'."

D-Rex evolves from Dinoshi when fused with an Ancient DNA.

In Yo-kai Watch 3 Sushi, D-Rex is Angie's childhood friend. Even as Angie grew up and couldn't see Yo-kai anymore, he still watched over her.

History
D-Rex appears to rescue Nate, Inaho and their Yo-kai partners from the forces left by the UFO alongside Origin, Bunny Mint, and Hanzo, giving them time to escape with the aid of the Yo-kai Watch Busters.
