Is this from G1?

Yes, these are G1...Now the Constructicons ARE a Takara Reproduction from their "Encore" series...this version is identical to the original except for a few small points. The fore arms are black instead of purple, the cement mixer on the leg is purple instead of lime green, and the head has a new sculpt from the original. These reasons were to make the toy look more true-to-life to Devastator in the G1 Cartoon. I like the changes. i actually have the original head and arms and such, and the new colorings and sculpt make the character pop! ^.^

I still remember Devastator from Revenge of the Fallen, much more scary, and less focus on the individual Constructicons.

I dispised the "new Devastator" in the movie...and everything else beyond the 1st Michael Bay movie...the franchise is dead to me...except for the originals that sparked the fandom! Wanna see a REAL Transformers movie, watch the original animated one from 1986 ^.^ Oroson Welles, Leonard Nimoy, Robert Stack, and many more added outstanding vocal talent to this epic Transformers saga!

i have an astrotrain like that
i want a blitzwing though

I HAVE an extra Blitzwing with no stickers on it...but the tank turret is completely missing as is the peg that held it in place >.< Poor thing got played-with to death Xp He's easy enough to find on eBay though. Just type in Blitzwing G1 Every month or so one goes for REALLY cheap (and complete if thats what you're looking for)

my dad has one tho

I too have the 2013 Takaratomy Encore Devastator as well...

As well as the 2009 Encore Bruticus...
