Finally, after a solid month of working on this and several more designing the figure, I have completed a “Transformable Power Up Optimus Prime”.
What makes this “Power Up Prime” unique is that it is probably the most movie/ concept art accurate “Power Up Prime” that has detachable Jet Fire armour so that Optimus Prime can transform into truck mode.
Plus, the way the attachments are designed are so that different parts of the armour moves with body parts to maintain high articulation in “Power Up” mode.
The original toys from Hasbro allow a Leader Class Prime to combine with a Leader Class Jetfire but it is not really movie accurate.
There are several excellent customizers who have created beautiful “Power Up Primes” but the combined figure cannot transformed as the parts have been permantly glued together.
All my attachments are through magnets hidden/ embedded in Prime as well the individual armoured parts.
I did the standard ROTF Prime modifications including a ball-jointed articulated head, and TFTM hands.
Paint job is fairly standard with a slight weathered look. The shade of black for Jet Fire parts was created with a flat black base, a dusting of gun metal and dry brushing of semi-gloss black.
I used a Buster Prime and repainted it along with giving a black wash over the entire exo-skeleton.
Here is a picture of the original Leader Class Optimus Prime from Hasbro:
Here is my custom version of the figure. Besides the paint job, the major difference is that there are tiny earth magnets embedded throughout the figure so that it can “power up”.
More on this later, here are the pics of my “Revenge of the Fallen” Optimus Prime:
In the “Revenge of the Fallen” Transformers (2) movie, Jet Fire sacrifices himself so that Optimus Prime can take his parts and armour to form “Power Up Prime”.
Here is the concept art for Jet Fire as well as the original toy from Hasbro:
Here is the concept art for the “Power Up Prime” as well as the “Power Up Prime” combined toys from Hasbro:

Here is my “Power Up Prime” that is created from the individual Optimus Prime from above.

Jan 2011: Check out the complete custom battle damaged Power Up Prime here.

Here is the detailed breakdown of the custom scratch work:
All of Jet Fire Armour parts were built from scratch with Jet Fire and Gundam parts including a whole lot of “kit-bashing”. From head down:
Jetpack
- The thrusters are completely custom made from a bunch of different parts.
- The main extensions are secured to a base that has large magnets attached to the underside. The magnets attach through to the batteries inside Prime.
- There are four arms that extend to the outer half shell of each thruster unit.
Shoulder Pads
- Custom-made shoulder pads attach to magnets embedded under Prime’s shoulder pads. The magnet positions allow the shoulder pads to move as the figure articulates
Shoulder Guards
- Custom-made shoulder guards attach to the steel pin on Prime’s shoulder with cylinder magnets. This allows the shoulder guards to swivel out of the way when arms are articulated
Back Wings
- The entire wing assembly detaches as one unit and both wings can swivel to different angles.
Chest Plate
- Chest plate with rib armour was made from different parts and fabricated as one assembled unit. They attach to cylinder magnets embedded into the sides of Prime’s body
- The chest plate also pushes up Prime’s chest window armour to give him a more buffed look in “Power Up” mode
Front Thigh Guards
Inner Thigh Guards
- Sculpted to fit around thighs from Gundum parts
Knee Guards
- Custom made from different sculpted parts attached via magnets
Shin Guards
Leg Wheel Guards
- Cut from Gundum and Jet Fire parts and each attach via two magnets to keep it in place without rotating with the wheel
Feet
- This is my only ‘cheat’ in the custom. In designing the extended feet/ leg and creating a movie/ concept art accurate look as well as maintaining stability of the “Power Up” figure, I figured the best way to to just switch feet for the “Power Up” mode. The “Power Up “feet are custom made from many different parts including the feet from a ROTF Leader Class Prime
Forearm Guards
- Cut from Jet Fire parts
Weapons
- Custom BFG with blue LED with ammo belt
- Custom Double Gatlin Gun mounted on forearm with ammo belt
- Buster Prime Canon
This has been the most challenging custom to date, although, I was working on a custom Voyager Class Prime before this, which was also very tough. I stopped the Voyager Class Prime halfway to start on this “Power Up Prime”. So, that custom is probably coming up next.

Do you know of any one that is doing a “Buster” optimus prime blaster that can be bought just by itself?
Hi Mike, Not that I know of. Sorry!
how did you get the “shin guards together and the whole back assembley?i tried different things with my custom but now i cant cause its glued in one position.
Hi David, thanks for the comment!
The shin guards and the whole back assembly are each individual units that are epoxyed together from different kit-bashed parts. These “units” then attach to Prime via magnets. Magnets are embedded in Prime as well as epoxyed to the undersides of the “units”.
Does that make sense?

Hey, that is one damn great custom Prime you’ve got there! What was the BFG and the Double gatling gun made of?
Hi,
The BFG was combined from a video game gun replica (I cannot remember which one but I could just buy the gun and assembled it) and Jet Fire parts. The ammo belt is a model tank track.
The other gun is a GI Joe gatlin gun (comes with several figures from the movie series) with the Jetfir gatline gun added to it. Same type of ammo belt.
Hope it helps.

Oh yeah, and one more question, Did JetFire’s cane help in making this magnificent custom?
Nope, I did not use the cane and I did gut and cut up Jet Fire pretty bad.
Ohhhhh,okay,thanks for the info!
specifically what part did you use to build his jet pack?
It is a bit too complicated to explain. At least 4 – 5 parts from Jet Fire, Gundam and custom cut from metal – the red parts. The Jet Fire parts were also custom cut out, shaped and shaded. Use my model or the concept art and try to look at different toys that might fit in terms of parts. Star Wars and other space craft toys may also work.
great. thanks a lot.
can you recall which gun dam did you use
MS 18E Kampfer. Also a Stars Wars Crab Droid for parts of the feet and extensions for the jet thrusters.
great. I’ve been following this thread for some time now and I used the crab droid for primes feet and it worked great.
which of the crab droin feet did you use for the jet thrusters
Not for the actual thruster but the extensions. The Thruster cylinder was cut from an aluminum tubing and parts from Jet Fire etc were epoxied on.
Hi!
Your custom is avesome, but can you tell me how to make the swords to be re attachable on ROTF prime? The arm articulation is annyoing me with those swords but I dont want to screw them out all the time. Please help
Thanks! You first need to remove the blades and cut off the “spokes”. Then you need flat disc magnets. Epoxy one to each end of each blade and and one on the inside of the arm where you want the blades to be. The disc magnets will allow you to swivel the blades out or just detach completely. The magnets you wants are flat disc ones like those found here http://www.supermagnetman.net/

Thanks so much!

Hi Joshua, what strips are you talking about?
