James/Jimmy "ClashJTM" Martinez is a commentator and a friend of the Creatures, but he has only played with Seamus and Sp00n as of yet. His commenting style somewhat resembles Seamus' commenting style, featuring mainly sarcastic humor. He has met some of the Creatures at Minecon 2011. He had moved out to Colorado from California and shared an apartment with Seamus and AshhBearr, but moved back home for personal reasons.
- He can play the guitar and the bass. He performed Dammit by Blink 182 for Sly as a birthday greeting in this video: Happy Birthday SlyFox!.
- Clash has said during a livestream that he had been watching Seamus for a long time and Seamus was his inspiration to make videos.
