Tank

Tank is Rainbow Dash's pet.

Personality
Tank is first seen persistently wanting Rainbow Dash to choose him as her new pet, but Rainbow Dash refuses, seeing him as a useless, slow pet that will keep her grounded. When Rainbow Dash's wing is caught under a rock, Tank comes to her rescue and shows loyalty by lifting the rock and rescuing her in the process. She chooses him as her new pet when the other animals leave her behind, caught up in the frenzy of winning the race.

History
Tank is first seen in the episode May the Best Pet Win!. He initially lived in Fluttershy's backyard along with many other animals, but longed to be someone's pet. When Rainbow Dash arrived to get pet, Tank made many attempt to get Rainbow's attention, but to no avail. Fluttershy convinces Rainbow Dash to let Tank participate in the competition to determine Rainbow's future pet because "he has always wanted to be a pet." He is not at first considered pet material by Rainbow because he is slow and cannot fly, but wins her over with his tenacity. He is the only animal that does not flee from the avalanche accidentally caused by Rainbow Dash, and helps her when one of her wings becomes pinned under a rock. After Tank freed her he gave her a ride since she couldn't fly. In the final scene of the episode, he is seen flying around with a magic-propelled helicopter rotor strapped to his back and wearing aviation goggles, allowing him to keep up with Rainbow Dash and follow her in the air.
