In The Wonderbolts Academy Handbook, Fast Clip and Whiplash are named on pages 30 and 31 respectively. Fast Clip's description on page 30 states, "We all rely on Fast Clip to make sure training days run smoothly and efficiently. As a drill instructor, he doesn't waste any time getting down to business. It's all about training hard and staying in line. There's zero time for horseplay when Fast Clip is running the show." Whiplash's description on page 31 states, "Whiplash is one of the toughest instructors at the Academy. He tests ponies backward and forward, so they better know their stuff! He grades hard, too. There's no extra credit in Whiplash's world. Despite being a pony of few words, his image as a hoof-buster is mostly a legend. When he isn't putting cadets in their places, he's just a big softie."
