To convert Throttler into armour mode, fold the lower legs back 180 degrees at the knees so the lower legs cover the upper ones. Point each leg diagonally out to the sides then turn the Mini-con over and round so it's back is facing you and it's head points down. Fold the arms up so they now run diagonally under the underside of the legs. Pin onto Sledge (or any of the other commander figures) using the chest mounted Mini-con port with the larger robot's head looking out through the V formed by the legs.
This is probably the best of the Mini-con armour modes that I've seen so far, really works for me giving the impression of being some sort of jagged electrical bolt mounted on the larger robot.
To transform into weapons mode, fold the lower legs back 180 degrees at the knees so the lower legs cover the upper ones. Twist each leg round at the thigh swivel so that what was the open front of the folded up leg now faces inwards. Fold both legs back at the hip and bring them together - there's a small tab at the bottom which has a slot it fits in to to hold both parts loosely together. Fold each arm back and slide the tab on each arm into the slot on the flat surface of each leg.
What you get out the end is a clear purple drill. And it's the work of genius: a multi faceted cone that looks convincing as what it's meant to be. Any robot with a 5mm peg hole hand can hold Throttler as a hand weapon but since the back of the drill is the robot's chest complete with Mini-con port he can be mounted on any decent facing Mini-con peg. There's one on Sledge's shovel that allows Sledge to use him in vehicle mode as a drill attachment. Our old friend and favourite Armada toy Hoist was to hand when I opened Sledge and Throttler and quickly appropriated Throttler to peg onto the Minicon port on the inside of his fist. And of course any of the Power Core Commanders can attach him to their chest port to use him as a chest mounted drill. It was at this point I tried to turn Throttler figuring that if he's a drill he might as well go round when mounted on a Mini-Con post. Turns out the post fitted a bit tightly but Throttler still turned thanks to a pivot mounted between the chest and the rest of the body. So while the chest stayed still the rest of the toy, now the drill, span.
Overall: What a superb Minicon! Looks good in a robot mode which is full of articulation, is a decent armour mode and while, compared to some of the earlier Power Core Minicons, he only has one weapons mode is a good one that works, has some functioning articulation and is appropriate to the toy it's initially packed with. Superb stuff. Longarm is feeling that his "Best Minicon" status is threatened!
I fully expect a repaint to show up later packed with a different toy.
