Boy Bullies

The Boy Bullies are a group of up to three male Pegasi, including Hoops, Dumb-Bell, and Score, who have picked on Rainbow Dash and Fluttershy, calling them respectively "Rainbow Crash" and "Klutzershy". The three first appear in the episode Sonic Rainboom, Hoops and "Dumb-Bell" also appear during flashbacks in the episode The Cutie Mark Chronicles, and Hoops later appears in the episode Trade Ya! and the chapter book Twilight Sparkle and the Crystal Heart Spell. They are not named in the show, their collective title being given in the guidebook The Elements of Harmony and "Dumb-Bell" and "Score" being placeholder names, but Hoops is named in the chapter book. "Dumb-Bell" shares his colt design with "Chip Mint".

Season one
In Sonic Rainboom, as Rainbow Dash and Fluttershy return to Cloudsdale for the Best Young Flyer competition, Hoops, "Dumb-Bell", and "Score" meet up with them as they arrive and start teasing Rainbow on how she got kicked out of Flight School, how she supposedly doesn't have a chance on winning the competition, and how the sonic rainboom is supposedly an old mare's tale, which really brings Rainbow down. A short time after Rainbow's friends arrive to Cloudsdale and have been touring the weather factory, the three stallions admire Rarity's new wings that were made by Twilight Sparkle. After they witness Rainbow Dash saving the Wonderbolts and Rarity and subsequently winning the competition, they start to gain respect for Rainbow, and apologize to her for giving her a hard time, and they ask Rainbow if she can hang out with them, but Rainbow rejects their offer to hang out with the Wonderbolts.

In The Cutie Mark Chronicles, Hoops and "Dumb-Bell" appear as colts in Fluttershy's and Rainbow Dash's flashbacks, Hoops already having his cutie mark and "Dumb-Bell" not yet having his. In Fluttershy's flashback, after she attempts to fly but fails, the two young colts start to harass Fluttershy of not being able to fly, only to be stood up to by Rainbow Dash (or Rainbow Crash as they call her). Rainbow decides to challenge the two bullies in a race, but while racing, "Dumb-Bell" crashes into a column and Hoops gets spun out, and right after, Rainbow Dash preforms a sonic rainboom and earns her cutie mark.

Season four
In Trade Ya!, Hoops appears as a colt in the present day at the Rainbow Falls Traders Exchange.
