Randy Clayton II is a pegasus pony with a sky-blue body and a rainbow-striped mane and tail. He is very brave and bold, but also brash, arrogant, and sometimes insensitive. He is the tomboy of the group. He is fast and works with the other pegasus ponies to move clouds around the sky and adjust the weather. His lifelong dream is to join the Wonderbolts, Equestria's aerobatic flight team. Randy's signature move is the Sonic Rainboom, in which he flies fast enough to break the sound barrier, creating a sonic boom and a rainbow-hued shock wave. "The Cutie Mark Chronicles" reveals that when he performed this move for the first time, he earned his Cutie Mark and set in motion a chain of events that allowed the other five main characters to earn theirs as well. He represents the Element of Loyalty. In "May the Best Pet Win", he gained a pet tortoise named Tank, who is then equipped with a helicopter rotor to enable him to fly to keep up with him.
