Alt smokescreen to get back into car mode by far.

Of all the TF's I have right now, probably Universe Dinobot Striker is the biggest PITA... 20th Anniversary OP is fairly easy to me. I rarely transform him though, as I'm always afraid he'll break. As for my Alts... I've only transformed Smokes twice and Sideswipe once. It's just to much of a pain to get them posed exactly like I want them... :tflaugh

I like 20th Anniv. Primes transformation. I think it's not too hard at all.

 

Alternator Smokescreen, though, is a real pain, and it's tough to pose those crazy 'legs'. I have trouble getting his arms right, it always seems to me like they're on backwards, and those bloody magnet things for the steering keep getting majorly in the way.

 

Sidewswipe's cool though. Real nice for posing.

 

The worst of all time for me is this stupid little Beetle that's a part of Tripredicus, a big Beast Wars combiner type dude. I've lost the instructions and that damn Beetle is stuck half way. Blowed if i can figure out how it was supposed to go. Somebody else on this site had the same problem.

for me it was all about Big Convoy...gods I fought with that bad boy for an hour...

Well I would say alt smokescreen but as soon as you have done it once it is easy. I would say unicron, he isn't at all complicated or hard but his size makes it a bit of a mission to put back into planet mode. It is just too physical to be fun, there is too much movement with the arms required, other you can just transform in you hands and not move your arms at all.

Definitely Ramhorn, the beetle from Tripredacus. UGH!

RID Sideburn was a pain for me, espcially for one that size.

 

G1 Omega Supreme is another pain. He's easy enough to transform, but it takes too long to do so, then you have to make sure you didn't lose any of the litle leg clips.

Gonna have to go with Magnaboss from Beast Wars Neo. Those three dinosours have to fit together just right, and its just a pain in the ass to make sure everything is lined up and set in place. What really sucks is I got this guy off of ebay, loose no box, and had to figure everything out from pictures off the net. I am NEVER taking him apart. It will remain in robot mode for the rest of eternity, or until I have to sell my collection to pay for a new prostate.

alt smokes those dan legs! the arms are easy

BW Neo figures in general.

 

Mach Kick, Dead End, and Big Convoy top that list though.
