While reading the article on kibble @ TFwiki, I came across the anti-kibble section. After reading that part, Here is my theory: Anti-kibble is "kibble" that becomes some kind of tool. Something like: Animated Blurr, when he transforms his hood becomes some saw-tool. Cybertron Crosswise, when he transforms, his roof and windshield becomes a shield. And a non-TF example: The Zeta Gundam. When it transforms into robot mode, the Wave Rider's(It's jet mode, if you will) nosecone becomes its shield. This is confusing me... off-topic: I'm not sure if a topic like this belongs in toy discussion, but if it doesn't belong, mods, please move it.
