With my new job, i've been slowly collecting the original Generation 1 of Transformers. I try to stick to the one's in-show only which narrows the collection only slightly (Massive redecos, repaints, and randoms weren't prevalent until Beast Wars)

The back is the Decepticon Team Front is the Autobots

Cassettes are: Frenzy, Rumble, Ravage, Laserbeak, and Buzzsaw

Decepticons are: Reflector, Skywarp, Starscream, Thundercracker, Soundwave, and Megatron

2 rows of minis: Cliffjumper, Brawn, Windcharger, Bumblebee, Huffer, and Gears

Cars front row: Hound, Jazz, Sideswipe, Prowl, Bluestreak, Sunstreaker
Cars back row Wheeljack, Trailbreaker, Ironhide, Ratchet, Mirage

And of Course, the one and only Optimus Prime ^.^

These are their vehicle forms
