- Rolly Roll - A lighthearted and carefree girl. She always tries to help others who are in trouble, but can sometimes be a bit "scatterbrained".
- Chick Poacher - Chick may look small but his spirit is strong, giving him a misplaced air of superiority. He has a tendency to act before thinking, which always makes his friends a little nervous. He wears teal goggles on his head and seems to have the biggest of the chicken combs on his head.
- Bantam Scrambled - The heavy and powerful friend of Billy, Rolly, and Chick. He wears the largest and most distinctive clothing of the entire human crew. Bantam is a gentle giant and only uses his strength to look after his friends. Despite his rough outward appearance, he adores cuteness but hates injustice.
Appearances In Other Media
Billy Hatcher later had a minigame in the Eyetoy game Sega Superstars for the PlayStation 2. He also made an appearance in Sonic Riders as an unlockable character. He is also a playable character in the racing game, Sonic & Sega All-Stars Racing. Later Billy and his friends appeared in the Archie Comics crossover event Worlds Unite, where they defeated Wind Crowrang after he invaded Forest Village.
- His character strongly resembles that of Sonic The Hedgehog. In fact, if you look at the box art of Billy Hatcher and the Giant Egg and Sonic Adventure 2, you will see that Billy's pose is very similar to Sonic's.
- Billy Hatcher was created by Yuji Naka, the same creator of Sonic The Hedgehog.
- Interestingly enough, he does not appear at all in Sonic & Sega All-Stars Racing Transformed, yet Rolly, Chick, and Bantam do make cameo appearances.
