So I thought the Omega Supreme custom I posted about was the be-all end-all of custom Transformers. I was sorely mistaken though as this behemoth has come upon the scene. The name of this thing is Extinction and he is a combination of the Dinobots and was made by frenzy_rumble. This guy is five normal sized Transformers combined into one and he is part original Gen 1 figures with a bunch of customization and great matte color scheme. I love that you can see Grimlocks head inthe chest and the prominent figures on his arms. He can be broken down into his smaller pieces and they also transform so it’s a crazy level of engineering to get these pieces to fit together. You can get more info on this at the Seibertron forums.  Here are the individual Auto bots that make up the overall giant Extinction:

Grimlock

Slag

Sludge

Swoop

Snarl
