My first actual full kitbash project involving a Transformer toy and I'm pretty pleased with how he turned out in the end (except for the paintjob, which was entirely done with markers).
Upgrade parts mainly comes from MG FAZZ Gundam, with random gundam bits here and there for the head, hip-armor panels and the tank treads. The Autobot emblem comes from Leader DOTM Bumblebee's MechTech.
Without further ado, I present to you all, Double Zeta Optimus! Cybertronian Battle Tank
Holes drilled into Optimus' arms for upgrade installation
A bit crooked positioning here because the additional piece under the cannon(to stabilize the bot mode) was not added until later, so they kinda got in the way in alt modeHexa-Rocket-powered!
Assembling the core upgraded bot modeFOC Double Zeta Optimus Prime!!
BackView: The blue piece pegs into FOC OP; had to cut out some small pieces out of his butt :p The 2 red pieces are there to prevent him from having a broken back.
No Gundam-inspired mod is complete without the addition of beam sabers. These fit nicely into the side armor panels
Here he is with Astray Red Frame's weapon...
...which had been modded to become the Master Sword!
So you've been wondering where did that sword comes from, and where does that rocket backpack with the Autobot emblem had gone, eh? We'll get to that, but lemme introduce you to...
...the Metal H.A.W.K
! (Heavy Armor Weapon Kit!)-Old school cheesy acronym!
So that, and all that missing pieces will go back into Prime to form his...APEX ARMOR!
(NB: Unused MH's parts missing from the rest of the photos actually transforms into a huge blaster of some sort, but it's just too heavy for the old-school gundam palms to handle...
Back view, this guy's gonna leave Jetwing in the dust trails
Have at you, Decepticon scum!
Wielding the MasterSword (This is also the last time he'll be using it; it's waaaay to heavy for the old Gundam pvc joints to handle all that weight, even with Giant's aid)"Why don't you pick on somebody of your own size!?"
And that's all for this project of mine, folks! Thank you for your time!*Brofists*
