The Japanese name for U-Turn is Round-trip. The hiragana of this is とんぼがえり, pronounced tonbogaeri. The first part, tonbo, means dragonfly. Given the love for play on words, this could possibly be why U-Turn was classified as a Bug-type move. And though there are other Pokemon that can learn the move by leveling up, 2 out of the 17 are Yanma and Yanmega. You know, the dragonfly Pokemon. As a bonus, they’re the only 2 out of the 3 Pokemon that receive STAB from using U-Turn.
