Micromaster Small Transports

At least one of these has had a lot of popularity with 201's hall of fame nomination. Each of them except Flattop was a transport truck. I had most of them as a kid. I remember selling a couple of them at a yard sale.

First up, we have Erector, who was the one nominated in 2011. Mostly based on his name, while there were a few people that actually like the character. He's a builder not a fighter. The Micromaster has a unique transformation with the chest flipping around.

His vehicle with the trailer is a crane truck. The crane goes up and down, and turns 360 degrees.

He is the only one of the four that doesn't have a flying alt mode. His trailer turns into a base. 

The second Autobot is Overload. His bot mode resembles Optimus Prime. He is a tactical genius. 

His alt mode is a car carrier. The back end opens and you can drive Micromasters inside. It fits two comfortably

His trailer transforms into a jet. Pretty straightforward, there is a connection point inside so he is locked in there tightly.

First out of the two Decepticons, we have Roughstuff. His bot mode has a lot of junk in the trunk. It actually detracts from it somewhat imo. He's a trigger happy sniper that never aims according to his tech spec...which doesn't make a whole lot of sense to me.

His alt mode is a missile truck. Both missiles are removable, and them and the guns can go up or down. I really like the truck mode for the Micromaster, so I guess it kind of makes up for the weird looking bot mode. 

His trailer also turns into a jet. 

Lastly, Flattop. This figure doesn't make a lot of sense, and sticks out from the other three by not being a truck. I would have preferred a truck I think. He's the scourge of the seven seas, sinking everything. His bot mode is probably one of my least favorites from all the Micromasters. I can see where they were trying to go with it, but I think the colour break ups could have been done better to make him look less strange. 

His alt mode is a jet on an aircraft carrier. It actually is pretty good looking. I like that the front "landing gear" peg actually can peg into the carrier. 

The carrier's jet mode is actually pretty good. It really looks like a jet that could actually fly. There is retractable landing gear under the nose of the plane.

They were also released in Japan under the Zone banner with no changes except they were sold in boxes instead of on cards, and all four of them were Autobots.
