All right, let's give a back story for those not familiar with everything... The guy in the foreground is Star Saber. And Speeder, behind him, is the Micromaster Partner of Dai Atlas. (I refuse to call him his "son" until I know how that's supposed to work, outside of Japan just being weird.) If you're been reading the Transformers MTMTE comic book recently, you know what happened to Dai Atlas, and why Speeder would be attacking Star Saber.
Why dd I draw the traditional Star Saber as opposed to the recent redesign by Alex Milne? Because dammit, I paid for that Ark Compendium book with the various model sheets and by God, and I'm gonna use it!
Hope you like it.
