Micromasters first appeared in 1989, to compete with Galoob's Micro Machines, which were Hot Wheels but a lot smaller, to put it in basic terms. Micromasters of course had the added bonus in that they transformed into tiny robots as well, and a whole backstory was created in the comics whereupon fuel had become scarce on Cybertron and the Transformers therefore had to downscale in order to keep running. (Dreamwave went a bit further than this, to make them another faction completely, run along the lines of street gangs, but this is generally considered awful. Along with most of DW's stuff)
I was down with Micromasters from the get-go. I don't know what it is, but I like the little guys. From the very first time I got a set of my own (the Off-Road Patrol), I was hooked. The Sports car Patrol didn't help any with my addiction.It didn't help that their Tech Spec bio was pretty rad, either. A team of mini miscreants, whose main funtion is clearing the road for their bigger brothers? Count me in, because that sounds like a lot of fun. It helps that their designs are cool, from the hot hatchback glory that is Blackjack, to my own personal favourite, the quite frankly eye-searing electric neon blue and amazing naming that is the mighty Hyperdrive. Everything about these guys is immensely cool to me, and for the life of me I can't explain why. It must be some kind of primeval thing.
Sadly, they didn't appear too much in the original Marvel comics, mainly because their Air Strike Patrol cousins got all of the love, being pitted against the Race Car Patrol. I should think that two sets of cars battling each other was deemed too much, and so Blackjack and the boys didn't really get much of a look-in. As for the DW 'effort', let's just forget that ever happened, and hope that IDW come up with something someways down the line. Although I'm not going to hold me breath on that one.
They toys, how shall I put it, are SPECTACULAR. As I stated earlier, they're four mini bundles of joy, all distinct, all different (apart from the transformations, which are ALL THE SAME. Get used to that with Micromasters.) One running theme you will notice is that of colour reversal; Blackjack and Road Hugger share purple and black; Detour and Hyperdrive yellow and blue. Personally, I like this and think it's a clever way to make these toys economical; some people will think of it as cheap and possibly even a bit nasty. But then Micromasters have always been a bit Marmitey, I find.
My love for Micromasters is pretty well known by now, I should think, so I won't labour the point too much, but I do think that everyone needs at least one MM set in their life at some point. The Sports Car Patrol isn't a bad one to have, not at all. I heartily recommend them to anyone looking to purchase a set. If you only get one, get Hyperdrive. Because he's awesome.
