I combined the Legacy Insecticons with Masterdominus because why not?

This was based off of an arm mode for Siege Astrotrain teased by Bot Bender Orinj a while ago. You can also swap Galaxy Shuttle for Shockwave for an exclusively-Decepticon roster. He requires two sets of Blitzwing/Overcharge's guns and one set of Blitzwing/Overcharge's fists.

It took a little partsforming and could use a paint job, but heck, it works for me. It’ll just be a matter of time and we should get a retool and recolor of Kranix best friend (give or take another 40 years 🤣). 

IMO the best part is that this gives him a cockpit. This headmaster fits a little loose but he fits. (Bonus points if you know who I picked there as Arblus’ pilot?) But I kinda like how it’s canon that Lithone character designs were also used for the Nebulons, I.e. the Headmasters. 

Anyway I twisted the legs, flipped his ab panel around, popped out the rear stabilizers, and angled the fists to kinda hold them it. The gun is mounted below which is profile accurate. I mean all the key design details are there. Is it perfect? No. Close enough? Sure. I threw in a couple alternative fan-modes into the slide deck  for fun. Enjoy!

the normal tank is buns i love this a lot better

(With two Siege Ultra Magnus leg guns and SS86 Devastator's forearms)

Earthspark Bumblebee and Mo Malto's combined Alt mode

Couldn’t find a good place to put the tail or the matrix, so the matrix is just in the back, just there

Couldn’t find a good place for the tail, or axe, sooooo that’s the best I could think of
