It's not the same as Hall's Outsider's Edge cos he only holds them up at one of his shoulders and he falls down to his knees. Hayabusa and many others also do this and it's very similar to El Samurai's Samurai Bomb.
The fire thunder powerbomb is like any powerbomb except on the way up some people who use it (Onita, Sasuke) instead of having there head in between the opponents legs, it's all on one side/shoulder, then the impact into a pinning position (like Kawada after the powerbomb or different variations too) also i've seen it done differently like Onita and Sasuke when the opponent is coming down they go down with it onto one knee and then pin(kneeling) it all depends on the person using it, i've seen Hayabusa, Kanemura, Tanaka, Gannosuke majority of the FMW crew etc all do the fire thunder powerbomb and each individual has different ways of executing it but the impact and pin at the end of it is all the same just varies on certain things.
Also I believe Sasuke's "Razor Edge" type move is called Splash Mountain if i'm not mistaken.
Well, according to http://toryumonusa.tripod.com a GREAT toryumon site, the Shubain is a "Side tombstone driver, similar to the Air Raid Crash or a reverse Emerald Frosion". Havent seen it, but it sounds like Mike Modests backdrop driver.
The perfect driver is when "Opponents legs are crossed and is hoisted up and dropped into a Falcon Arrow"
I just have to know...is there anyone who does anything even resembling this move from Super Fire Pro Wrestling X, it's called the Eiffel Parachute
That's just one of the moves in there that I doubt actually exist. The Deadly Go Round is another one. You grab your opponent by crossing your arms, uncross your arms by flipping over sideways, setting up your opponent up into a jumping powerbomb. The Bullnoi Stomper is a good one too, which can only be described as a twisting jumping shoulderbreaker, which I'm pretty sure would likely kill the person taking it, or at least stop them from ever eating solid food again.
The moves from firepro X that you mentioned and a few others in the game are taken from the firepro arcade game called blazing tornado. The game featured fictional wrestlers and the moves that appear in the other firepro games are their finishers. They are all fictional and exaggerated , and I doubt they could even be pulled off, and in most cases if they could the person taking them would get themselves seriously perished
I've heard so many different names for Misawa's finisher..... Emerald Frosion, Emerald Flowsion, Emerald Frozon, Emerald Erosion.... I lost count how many names people gave it
