Position: Forward  Nationality:  Canadian    Height: 181 cm  Weight: 65 kg  Team: Sledgemamma    River is the new forward of Team Sledge Mamma and a rival to Takeshi. He used to be the back-up pilot for Team Satomi and was frustrated about being on the bench. River is an outspoken and pushy troublemaker and shows it when he pushed Takeshi into a security machine during a confrontation in the hangar, locking them in for the night. River was offered to replace Liz as defender at one time, but it was not the forward position he wanted. He then decided to leave Team Satomi so that he could challenge Takeshi in a friendly rivalry rather than a hateful one.

In the year 2048, people are raving about a fighting race called &ldquo;Immortal Grand Prix&rdquo;, or IGPX in short, which is faster and more exciting than any of the existing motor sports. The phenomenon is so big that an entire city was built for the racing industry where competitions take place on a huge track. In the &ldquo;Immortal Grand Prix,&rdquo; two teams of three IG machines, high-tech humanoid mechs driven by humans, race at speeds greater than 400km/h. The teams make three laps of a 60 km course while intercepting the opponent as they vie for a first place finish. The best machine performance, the best pilots and the best teamwork are the only factors that can make them the winners.<br><br>
