Had to dismantle Grimlock 1.0 a couple years ago for parts, so I decided to do a newer version. Still transforms without any partsforming. Backpack's the name of the game!
Yeah, that's kind of the nature of the beast when you try to do transforming Kreons. Basically, a backpack that wraps around the minifig to create the alt mode. I always had that idea of having a backpack rack in my Kreo Ultimate Prime trailer so Kreons could actually choose their alt mode before a battle, so Bee would be free to turn into a t-rex if he felt like it.
