Here are a few videos from Japan Expo 2004, where some attendees created costumes that actually transformed! They made costumes for Mixmaster, Long Haul, Starscream and Optimus Prime – which is easily the coolest one!
In this next video, you’ll see a stage performance that they created – it’s kinda lame, but you can see the effort that went into some of the costumes.
I would love to have an Optimus Prime costume for Halloween this year! 
What about you – which Transformer would you dress up as?
Now that is a tremendous waste of time. I wish it had sound.
Really? I thought this was so cool! If I had the skill, I would make one for myself for Halloween!
no way man.. this is really cool.. sound or no sound :0
I’d love to have one of those for Halloween! If I had to pick one character, I think I might go with Starscream because I always liked him as a kid.
The Starscream costume was pretty cool but the Prime suit is so detailed – and actuate!
That was cool
Best…cos-play…ever.
Interesting
Never thought the cosplay really transform,,,
Nah. I watched it again, and it’s still a stupid waste of time. Ha
Haha, that was great, i wounder how long it took them to make them lol
That’s what I was wondering too, I looked around Internet for more info but couldn’t find any – you’d think that people who are so creative would have a website!!
haha… that’s cool!
If I owned one of those suits I would end soooo many chumps.
The Starscream costume was pretty cool
it is kinda cool. don’t tell anyone i said that…
the video was hilariously fun, I enjoyed it so much. The ppl who made these are so talented. i am a decepticon in the haus so I loved starscream. but I agree that optimus was more detailed. I wish I could get those costumes for halloween.
where can i buy one of these transformer costumes online
OMG thats cool!
