Defictionalization: The Kinniku Buster is used as a finishing move by Samoa Joe, although he falls back to make it more like a suplex rather than dropping straight down to avoid breaking his opponent's neck (or worse) in real life.
There ARE ones who use the original sit-down version, but they're exceedingly rare due to the stress on both the victim's neck and the attacker's tailbone. Kinnikuman doesn't have this problem because, you know, he's superhuman and he's really trying to beat the other guy up.
The Robin Special has also been used in real life, but it's not done in the same way as Robin Mask does it and not done often, for obvious reasons.
Names to Know in Anime: Interesting in the fact that the anime was released at the time when most, if not all of the voice actor listed were not exactly stars at this point of their career.
