The Energon Pub

Please can we have titan botshots like Unicron, Primus, Omega Supreme, Tripticon, Metroplex, Fortress Maximus and so on and so fourth OR EVEN JUST COCEPT ART SO I CAN MAKE MY OWN.

Toonbot is the guy you want to get ahold of. I dunno if he is/was/has interest in doing any of those, but it couldn't hurt to ask. I'm not sure how much of a following Bot Shots still have, but he does AWESOME work. I follow him on Facebook and he's been posting pictures of molds he's been making, so he's certainly capable of creating molds from scratch.

You can also ask in the Transtopia forums! Plenty of great talent over there.
