They were all voiced by the late Joe Alaskey, Jeff Bennett, and Rob Paulsen respectively.
Nuk, who while is the largest, is also the least intelligent member, personally claiming he'd rather just eat than use his brain. Yak seems to be the most intelligent, but seems to have an increasing difficulty with fleas. Sumac appears to be the smallest and most skittish individual, as well as laughing frequently. They first started off as villains, but later, they refused to continue forth with Niju's evil plan when they finally realized the truth of the situation around them. The three aided Aleu in her return to the ice flow, resulting in her takeover of the pack's future.
They disappeared across the ocean with Aleu and the rest of the wolves.
- The trio is similar to Shenzi, Banzai and Ed, from The Lion King.
- They are the only secondary antagonists in a Balto sequel, as the third sequel Balto III: Wolf Quest, has no true villain. They are also the only antagonists in a Balto sequel to redeem themselves in the end.
- Though they are antagonists, they are not evil, as they appear aggressive due to their hunger and they follow Niju because they thought he would help them with getting food. They eventually defy Niju's orders near the end of the film, by following Aleu and the wolf pack to follow the caribou.
