Since there isn’t an official instruction guide for the combiner shown during The Hasbro Pulse Fan Fest Event, I decided to take it upon myself to study the video frame by frame and recreate what was shown, and I believe this is the most accurate guide for what was shown in the video,
Don’t forget to discuss this on our Discord server: Discord.gg/allspark and on the forum thread.
A. Start off with both robot legs from Ractonite.
B. Add the hip from Paleotrex and shoulder from Wingfinger and attach them like so.
C. Next connect them to the torso mode of Paleotrex with the dino skull in front.
D. Attach the lower legs from Paleotrex in the 5mm pegs found in the center of what is now the knee of the combiner.
E. Take the Pterodactyl head minus the head crest from Wingfinger and attach it to the hole normally used on Paletrotrex for his chest plate to form a tail.
F. Now you’ll wanna take the hip joints from Wingfinger and attach them to the pegs found on Paleotrex’s left shoulder, or the part that forms the tail in T-rex mode.
G. Attach that assembly to Ractonite’s torso using the pegs that the front legs attach to in dino mode.
H. and then attach the aforementioned legs to the knees from Wingfinger like this.
I. Now you’ll wanna take the other shoulder from Paleotrex and rotate the dinosaur hip joint 180 degrees and then attach those pegs to the hip joints from the legs forming the upper torso assembly.
J. Flip this upper torso upside down for now and you’ll see a port under the Ractonite legs, use the pegs on the side of arms from Wingfinger and plug them in where the hands can fold towards Ractonite’s torso near the back end,
K. Grab the lower legs from Wingfinger and plug them into the hands from the same toy to form shoulders.
L. This part is easy. Grab both lower arms from Paleotrex and just plug them into the ports found at the end of the feet from Wingfinger.
M. Take the dinosaur head from Ractonite and attach to the same area you would for alternate mode.
N. Now there is a port inside the upper roof of the mouth, Grab the crest from Wingfinger and plug it in to form the robot’s head and face.
O. Take both halves of the robot and just plug them together using the peg found on Ractonite’s robot mode head, to form the waist of the combiner. and you are finished.
That’s how you form the combiner from the Fan Fest video, hope this guide was helpful and can inspire you to add this to your display or make your own combiners.
