No doubt, you guys are all familiar with Sandstorm, one of the three Autobot Triplechangers. Octane, a Decepticon Triplechanger, is also a popular character.
See, the thing is it's been quite a long time since the last time I watched the cartoon including Sandstorm and Octane. I simply remember there's one particular episode showing Sandstorm and Octane have a race. They transform into vehicles, and then into aircrafts. Plus, they are quite friendly to each other. I have to admit I've already forgot the precise scenario. Consequently, you guys are my hope to figure out what's really going on.
If you can give me complete bios about Sandstorm and Octane, plus a brief explanation for the relationship between these two, I will be truly grateful.
