With this latest version of Omega Supreme I've started looking through my collection for TFs that match well with it's base mode. I've chosen to mainly focus on the color brown when it comes down to the following:

1. Generations Thrust
2. Siege Skytread (tank half)
3. Cybertron Brakedown

Honorable mention goes to (in no particular order):
1. Cybertron Thunderblast (minicon)
2. DOTM Whirl
3. BW Transmetal Rattrap
4. RID15 Quillfire
5. RID15 Scorponok
6. TR Chromedome
