Hiiro

Hiiro is a GT Sister from the Transformers GT portion of the Generation 1 continuity family.

She's gotta be strong and she's gotta be fast.

Hiiro (ヒイロ) loves being GT Maximus's race queen, particularly all the stagecraft, in which she always hams it up for the camera. She's a little emotionally manipulative.

Fiction

Transformers GT

Well, that's one powerful way to motivate faster racing, we guess.

At the race track, Hiiro and the other GT Sisters began to cheer on their respective Autobot partners in, uh, their unique ways, when they were interrupted by a fourth mysterious GT Sister and her equally-mysterious partner. Surprise, it was Noa and GT Megatron! Would he win the race? Hiiro better cheer extra hard and/or threaten to cry some more! Transformers GT: Mission GT-R
