They are officially listed on Chikara's site. I have to be honest, I haven't seen much of these guys but their look and what little I have seen really is like a fun throwback to the Road Warriors. I can just see these guys being so much fun in Chikara.

They had a nice run at KOT '12 in a tag gauntlet. They are also in Chikara's feeder fed, Wrestling is Fun. To me the only reason they look so "devastating," is that Chikara's roster is smaller, enhancing these 2 to look behemoth. They are still fun to watch though, but I don't see a lot of real flair out of them.
