TransFormers Crossovers...how cool are some of these?

If you follow me on Twitter or Facebook then you should know by now I have started collecting TransFormers, and I have 21 in my collection so far...I have some really cool ones from the Movies and Cybertron, but the Crossover TransFormers have REALLY grabbed my interest.

I first saw some of these a year or so ago and they were all Star Wars ones, with a Death Star that becomes Darth Vader and so on, and they expanded on those and some of them are really cool, like this:

These are really cool, but then recently I found that there were some Marvel Crossover TransFormers, and after having a quick look on eBay among other places found models like Hulk (becoming a Tank) and Spider-Man (becoming a motorcycle).  I have just recently picked up Captain America which becomes a 4x4!
However, the models in the Marvel Crossovers that are amazingly great have to be the Iron Man-Spider Man combiner...here are a few pics...

(I'm really hoping that someone will be generous enough to buy this for me for my birthday in 4 months time, but I have a feeling I will have to buy this one myself!)

Now, the Marvel and Star Wars Crossover TransFormers are really REALLY cool, but there is something even cooler in the Crossovers that is in Japan...Check this out...

OK, this doesn't look at like anything too special, it looks like a lorry almost from the TF:Animated series, but look at the logo on the side...does it look familiar?
Perhaps, if I show you you original coloured version os this and not the Halloween edition...

That logo looks like a very familiar, very famous Disney character, don't you think?
Well, heeeeeeere's Mickey (Or should I say Optimouse Prime)!!!

I think this is awesome, and even better still is the Donald Duck/Bumblebee...

And even better still for Pixar fans, it looks like there is a Buzz Lightyear one on the way too!

OK, I know the crossovers are not what TransFormers are all about really, but I think these are so cool, and aside from Legends and WST models, I'm seriously thinking about concentrating my collection mainly on these!
