I'd like to see Kup made in this style - but I worry that he'd look a bit odd with an Earth Mode - so perhaps he need to be linked to the Videogame offerings instead (even if he's not in it).
If this is the direction Hasbro is moving in m willing to open my wallet. The grabbed my attention for the first time in a LONG time with the Human Alliance sub line and the only other concept that would improve upon that (human mini figures with transforming vehicle characters) would be a return to the Headmasters and Target Masters. All i ask is that if Head / Targetmasters are made that they arent little bricks and have updated articulation . As much as i loved the art depicting the target Masters the actual weapon robot was a huge let down. Headmasters as well to a lesser extent thanks to the headmasters having shoulder joints to simulate actual piloting/driving.
Kup needs an update. He actually did have a Targetmaster toy, and his partner was named Recoil. He would look good as a rather new kind of pick-up truck, yet with his old-man face and characteristics. Old TF =/= old alt-mode. However, if we was in WFC, even as an NPC, they could make an even better toy! He was a cool futuristic truck in 1986, so a Cybertronian mode could work to emulate that style.
Yep I know Kup was a Targetmaster that was part of the reason I though this line was the ideal place for an Update of him. As for an Earth Mode the only vehicle I know of that might be suitable is either one of those pick ups that is loosly based on a 1940's style but in modern (Rollie in Defying Gravity has one) or one of those small Pick ups designed for carry surfboards. Otherwise just a normal pick up I feel wouldn't look right. I suppose something like that Gold LaserRod/Illuminator Pick Up might work the retro look might at least fit the character... but still it's tricky to ponder what wouldn't look out of place on him.
