That's right, Transformers customizer frenzy_rumble takes us to a place where no one has gone before. Grimlock, Slag, Sludge, Swoop and Snarl, all combining into one massive behemoth called Extinction. Words can't do this masterpiece justice, so if you haven't checked Extinction before, you don't know what you're missing out on!
Extinction isn't just one jumble of plastic like ROTF Supreme Devastator. No, frenzy_rumble has engineered the Dinobots to combine, as well as transform between robot and alternate mode! Check out Grimlock, Slag, Sludge, Swoop and Snarl individually.

And it says DINO-MYTE! Which is close to DinoMight! 
On a side note, who's the head supposed to be? I want to say it looks similar to Wheelie, but I don't want to say that in case there's no relation between them at all, besides maybe the 80's movie, and have people start trolling at me.
This just made my day!
