And now the moment we've been waiting for - POWERLINX !
The Powerlinx clip is a series of teeth with 180 degree turn symmetry - therefore one will complement another the other way up, and lock together. All the Powerlinx Autobots are marked with a gold Pentagon - similar to the Minicon symbol with an Autobot symbol within. Any Powerlinx toy can become both a top or bottom half of a combined robot - similar to multiforce. So Jetfire can become a body and be mounted on Ironhide as legs, and Ironhide as a body can be mounted on Jetfire as legs. The basic gist is each robot's legs are the limbs in either mode - there's a slight tweak to both to get them to form the Powerlinx robot legs, and a more major tweak to form the arms. In Ironhide's case the fold down the front of the car you expected as his TF forms the legs with the grill supporting the knees, in Jetfire's a lock holds the foot origami together. In the case of becoming the arms the individual robot splits at the waist and some detail on the legs becomes the hands. The small robot arms swing round the back (as does the head if you're making legs) and the Powerlinx clip is exposed with a little body twiddling. Push the 2 halves together and the clips recess into each other's body, and you have 2 big TFs. Both are nice robots. As a bonus Ironhide can be connected the wrong way round (the resulting legs look like SixShot's) and his weapons array can be used as a chest cannon ala RID Magnus :-)
These 2 are both great toys, and the resulting combined toys are good, steady and stable. Highly recommended, and deserve to sell by the shed load.
Jetfire was released in Japan without his electronics as Superlink toy SC-05 Skyfire which was also in boxset SS-02 with Roadbuster.
He's got a bland off white colour scheme. I only bought it to complete my set of PL repaints.
In Japan Overcast was released as SC-25 Sky Fire Sonic with no electronics, an Energon star & spear (from Skyblast) that he can't hold by it's mid point !
