Ox is second to last of the "Gobots" to be produced in the first wave of Car Robots.   Black and white blotches with a red cow skull/head painted on the hood make up this cow motif.  This is the only truck in the lineup.  Silver painted windows and grill also make up its' color scheme.

In Robot Mode you  can see his yellow legs and head with only his eyes painted red.  As with EagleKiller, I think maybe a red helmet and black painted eyes would've looked better.

It's definitely a different and unique color scheme (vehicle mode) and which is why Ox is my second choice of vehicles.  I dig trucks too :)

Robot Mode with yellow legs.  Also depicted with pearl white gun in hand.
