I'll list mine: Shellformers - Big Convoy. No doubt. Posture-formers (Less of a transformation and more of a "new pose" for alt mode...Energon Shockblast, many beasts, etc) - Beast Machines Mega Cheetor. I love the spindly dude. Hood-as-chest-formers - Alt Hound. Pure love. Robo-wang-formers (a part of the alt mode makes the 'bot "well-endowed") - Energon Starscream: original deco Parts-formers (something significant has to be removed and clipped on to a new place for transformation) - RID Magnus Alt-mode-on-one-side-'bot-mode-on-the-other-side-formers (turn it upside down and there's the other mode) - Energon Galvatron Beast-head-stapled-to-an-arm-formers - Transmetal II Megatron Fake-alt-mode-parts-formers (cheating to get a classic look) - RID Scourge Combine-with-an-accesory-formers - Powermaster Prime (reissue with diecast) Remove-the-head-formers - No favorite Brick-formers - G1 Bluestreak Non-transforming-formers - Mega SCF Starscream Auto-transforming-formers - That BWII jet... forget his name. Tripple-changers - Blitzwing.
