Tripod is the only main or recurring puppy in the series who has not been in the movies or the original book, and he has the most speaking roles than the other minor pups. According to the episode, "Dalmatian Vacation Part One: Road Warriors", he is not one of Pongo and Perdita's original fifteen puppies, and was one of the adopted eighty-four. Despite having three legs, he is very athletic, considerably moreso than the other Dalmatians (missing his front, left leg). He is Lt. Pug's favorite member of the Bark Brigade, and takes his brigade very seriously. According to "Mall Pups", he's captain of the brigade. Lucky sees him as his rival until the episode "Lucky All-Star", after they help Roger pull his car out of the mud. After that, he usually hangs around Lucky and the other pups. Originally, he was quite cocky, however after becoming more friendly with Lucky, this aspect of him starts to vanish. There has never been an explination behind his missing leg, though it's suggested that he was either in an accident and it was amputated, or it was a birth defect.
