| Team Sledge Mama |

| Team Sledge Mama are long-time veterans of the IG-1 series and are the tough guys in the league. Takeshi Jin of Team Satomi is confronted, but not intimidated by their leader Yamma. Nevertheless, the tension between them is evident. After River defected from Team Satomi, he replaced Yamma as the forward, and Timma was temporarily put off of racing (thus the lack of stats for him). As River becomes a part of the team, Yamma is ready to take their team to the championship. Unfortunately, Yamma is booted after their lack of getting to the finals in the second season. |






| Yamma plays forward position on Team Sledge Mama. He is one if the toughest guys in the league, along with the rest of his team. He intimidates competitors and is very fierce during races. He also stays in shape and may be a bit older than the rest of the IG-1 members, but nobody messes with him. |
| Timma plays midfielder for Team Sledge Mama. Timma takes after his leader Yamma, and can have no objections. That may be why he was booted when River Marque was asked to race for the races to come. Timma still knows how to keep competitors at bay, and is an excellent midfielder. |
| Dimma plays defense on Team Sledge Mama. He is one of the biggest and leanest guys in the league. He puts on a tough look for races, and still knows how to be appropriate for occasions. He is very true to his own character, but still knows his team's ability. He also knows how to cooperate with the team well. |



| River Marque (Age 17) was formerly of Team Satomi, and now plays forward for Team Sledge Mama. He now has a vengeance against Takeshi for taking his spot, but it's more of a friendly vengeance than a hateful one. River has been waiting for his chance to prove himself, and with Team Sledge Mama, he got that chance. |
