Nikki at times seems like the last dog to be running on the sled team. However, he is quite fast and manages well. He is one of the trio of dogs that hangtogether. Not much is known about Nikki, except that he's quite straightforward and sometimes likes to make jokes, like in the scene where Steele and Balto are squaring off about taking the medicine, he makes a bet with Kaltag two bones if Steele wins. His New York accent adds a unique quality to Nikki, which none of the other dogs have. He's narcissistic (formerly), intelligent, kinky (formerly), kooky (formerly), impolite (formerly), nice (currently), irascible, kind-hearted (currently), knowledgeable and independent.
Nikki is a brown Chow-Chow with brown eyes. He has a stout build and a large head in proportion to the rest of his body, which is emphasized by his tiny ears.
Nikki is a sled dog and spends most of the time being a sled dog. After he is done, he hangs around with Star and Kaltag, sometimes with Steele. When Steele was bullying Balto, Star, Nikki and Kaltag join the scene and bullied Balto alongside Steele. Little does Steele know that Star, Nikki and Kaltag talk behind his back. Nikki will be seen again when they have to race to see who's the fastest and is shocked to realized that Balto was there unannounced. He somewhat glares at him, but Nikki somewhat offers him a chance. When they're racing, he tries to make Balto the slowest, but Balto shows him self to be more agile and faster, as when Nikki kicks him at the face, Balto would gain the lead again when he's last. Later, he would be sent to go after the medicine, which they succeed, but Star later realized that they're lost. Steele refuses to listen to him, and Star would admit that they were just going in circles, but Steele would be overconfident and charge to a direction which they would be stuck for awhile.
When Balto finds them, everyone would be shocked, but when Balto tries to help, Steele would refuse. Kaltag was bet by Nikki that if Steele wins, then he'll owe him bones. When Steele hurts Balto, they would comment on what's happening, but they would be shocked to see Steele being so violent, and Star would be confused why Steele doesn't want Balto's help. After Steele fall from the ravine, he'll happily let Balto be a sled dog and now Balto leads the team to Nome, but Steele vandalized the marks and let's Balto and the Sled team to get lost. After Balto made a stop, he asks him which way, and Balto chooses another path but ends up where they just were, Nikki was now thinking that Steele would've been better at his position but Balto denies it and tries to take another path but most of the trees were Steele's and Balto ends up to a ravine, they almost fell but the medicine was gonna fall till Balto catch it and the weight ended the ravine from breaking and Balto fell with the medicine. They were sitting there for a while till they heard a howl, Nikki was worried that wolves will come to where they are and they check Balto and see him climbing he cheers for Balto for his wolf benefits and they confidently let Balto lead again. After come across some tress with marks, Balto uses his nose and he gets Steele's scent and now leads back home as they are happy to come back to Nome. He'll be seen when Balto and Jenna finally expressed their love for each other and congrats Balto his heroic actions and Star suggests that a statue of him should be built which Nikki and Kaltag agree.

When he is hanging around with Kaltag and Star. He would bully Balto if Steele is doing it and he bullies Balto with him but. Later, Nikki worries what Steele might do to him if he wins thae fastest dog but soon since Steele seems not to want any of Balto's help he bets on Kaltag to give him 2 bones if Balto wins. But Balto would not fight when Steele was almost hurting the medicine he was worrying what might happen to it but Star was wondering why Steele doesn't want his help but when Steele was gone for now, he'll happily let Balto be the lead dog of their sled team. But he'll realize that Balto made some may marks but a he isn't aware that Steele made some and he believed choosing him instead of Steele was a wrong decision this caused Balto to lead them to head the same path again. Balto rushes but Balto fell but he'll worry about him since he heard wolves' howls and he'll check on Balto and witness his wolf side giving him benefit and he'll cheer for Balto for his impressive actions and now since Balto finally relied on his wolf side, he used his nose to bring them back home. When they made home, presumably he thank Balto for all he did from them and congratulates him for his heroic actions.
when he is hanging around with Star and Nikki. He would bully Balto if Steele is doing it and he bullies Balto with him but. When they go and get the medicine retrieve it to Nome, he'll realize that Steele seems to not know where is he going Later Steele ends up on the game spot which he then rushes to another direction which would lead to them sliding to ravine and remain stuck there for awhile. Balto comes to help but he would bet Nikki bones if Balto wins but that Balto would not fight and Steele seems not to want any of Balto's help when he fell off to the ravine, he'll lead Balto lead and leave Steele behind.
When he is hanging around with Kaltag and Star, he would bully Balto if Steele is doing it and he bullies Balto with him but when Steele's not around or leaves he'll talk behind his back with the rest of them. He then would be seen in the fastest dog race with them but he was shock to see Balto come in unannounced? Later, they go and get the medicine retrieve it to Nome but Steele was lost and went to a ravine and remained there for awhile until Balto came to help but he was wondering to Kaltag & Nikki why is Steele like this. When Balto leads them back they'll have mixed reactions by making him lead but he'll again be stuck with them when Balto fell but he'll worry about wolves since they hear howls and they all check on Balto and witness his wolf side giving him benefit and they all cheer for Balto for his impressive actions and now since Balto finally relied on his wolf side, he used his nose to bring them back home. When they made home, they presumably thank Balto for all he did from them and congratulates him for his heroic actions.
