Take Cicadacon. Fold out the stinger. Fold the legs out to the sides, then fold the bottom of the arm onto the top of the arm. Fold the arms back onto the underside of the insect as far as you can and link the forearms together. Open the side panels out. Fold the sides of the beast head down besides the arms. Separate the robot's waist and fold each half to the sides and up - effectively moving the robot legs out into the sides of the insect. Remove the blades in the wings. Fold the robot head forward and open the back panel.
Sea Clamp: Turn the claws so the larger part faces down. Open the claws out leaving the inner blade hidden and stand on the claws. Separate the body as far back as you can to form the combined robot legs. Fold the beast legs in. Turn the head panels so they are sticking out the sides. Fold the robot legs down and remove the missile launcher. Fold robot legs up. Rotate beast tail/robot legs 180 degrees. Fold tail back exposing clips and a peg.
Ram Horn: flip the shell back up, remove the robot weapon and set to one side. Separate both halves of the head armour. Pull the front claws and the horn up through it. Pull the robot legs away from the side and straighten behind the insect. Fold the top half of the insect up at the back and the bottom (mainly the robot chest & legs) down at the front. Extend the bar that connects them to it's maximum length. Swing the top of the beast through 180 degrees so it's hanging down. Fold the robot legs up onto the plate in the arm, then swing the entire plate in through the arm so the robot legs are through the arm and the robot arms are hanging down.
The bar between both halves of Ramhorn slides into the back of Cicadacon - it'll only go in one way round and in one direction. Close the back up and fold the head back locking Ram Horn in place as the robot's arms (hence the name Motor Arm for the repaint) There's two thin strip posts at the base of Cicadacon - these mate with the clip at the top of Sea Clamp and Sea Clamp's peg has a hole to fit in Cicadacon's tail. When it locks together it's frequently quite solid but it may take some work getting it there. Then on other occasions you think you've combined it and it just falls apart in your hands.
Take the launcher and put the wing blades into it. Lock this onto Ram Horn's weapon. Place into the "hand" formed by Ram Horn's robot legs
Tripredacus combined form is a little biot of a mess colour wise - the purple and brown look mucky and clash rather with the green and the white. He bends at the ankle, has a ball joint bellow the purple knee cap, a bending joint above the knee cap, a rotational swivel joint above the knee cap & again bellow the hip and finally a ball jointed hip. That's a lot of articulation, perhaps too much in a toy that's supporting a fair amount of weight. The head turns. Both shoulders move back and forth. The claw arm rotates and bends to the side bellow the shoulder, bends in at the wrist via the tf the folds the legs onto the outside of the arm and the claw opens via 2 ball joints and a folding joint. The claw has a peg hole on either side that allow it to hold the weapon. The other arm rotates & folds to the side bellow the shoulder and also at the wrist. From there down we have the bending and ball joints on Ram Horn's fore legs, the bending joint under his neck and the ball joint for the head. A little bit of fiddling can get a passable three fingered claw out of it but it won't hold anything and it hangs so low that it virtually is scraping along the floor. Overall: I like one of the components a lot, and one of the others is a good mold just bad colour choices. The combined form however doesn't work for me and most of the problems come from the arms/hands (no proper hands !)
I like the name. Ls and Rs are somewhat interchangeable when translating from Japanese to English. One way we get Tripredacus and the other we get Tripledacus and something appeals to me having the word triple in the name of a three way combiner.
Tripledacus combines the same as Tripredacus - just substitute D.J. for Cicadacon, Gimlet for Sea Clamp & Motor-Arm for Ram Horn. Somehow the colours work better on the combined form - much brighter and less murky. Comments about construction and hands remain.
