Everything old is new again, but with joints!  EVERYTHING.  Back in the day (1987), there were this pair of Decepticons called Duocons because they were singular robots who each formed out of two separate vehicles.  The individual vehicles didn't do anything themselves other than form half a robot.  It's like, y'know, Overlord or a backwards Sky Lynx.  Battletrap was one of those Duocons, and he was a robot formed from a helicopter humping an SUV.

Anyway, now each of Battletrap's two vehicle components are their own guys!  Battletrap is now formed from Battleslash the helicopter and Roadtrap the SUV, each turns into a robot, and they're sold separately.

I like to think they're married and that the combined form Battletrap is their child.  Like, you know, one of them is J.D. and the other one is Turk, and J.D. hops on Turk and instead of running around yelling "EEEAGLE!" they are a consolidated robotical form.  The World's Most Giant Doctor.

I am in awe of the complexity involved in these toys.  Like, the other Legends Class toys are.... fairly simple.  They're all Windchargers and Brawns, who transform the usual Transformers way of rotating out the legs and pulling out the arms and being done after three steps.  But each of these two guys, Battleslash and Roadtrap, have a lot going on.  A lot of pieces going on.  I wonder how they budgeted this.  (probably by making the other guys Windchargers and Brawns)

Both guys have enough parts to not only form individually-articulated robots but also a fully-articulated combined robot form.  Heck, Battletrap's kind of got an ab crunch, even.  It's kind of nuts.  Yeah, a lot of the articulation doubles up -- Battleslash's neck joint is Battletrap's waist joint, for example -- but it's all still very impressive.

Well, okay, the vehicle modes are probably the weak link.  Both are vehicle-ish shaped blobs.  Roadtrap's SUV form is very obviously 50% a robot mode chest.  Battleslash's helicopter mode is obviously a bunch of wadded up robot parts.

Despite that, these two toys are very easy to recommend.  There's going to be some kids out there who only have one or the other (I don't think it mentions the combining aspect on the packaging, only in the instructions) and... I think their purchase will be good enough, really, without the other half, but these two really are a pair.  

It's guy love between two guys.
