Ultimate Warriors high speed style plus clumsiness made him a few enemies during his time in wwf, rick rude apparently 'warned' warrior to take it easy (warrior paid attention due to rudes hard man rep). Warrior has been knocked out twice in the ring, rude and Andre the giant (who apparently despised warrior!)..
bam bam bigelow once quit in fear of his life after being 'taught a lesson' by Andre. He came back a few years later having gained experience and had become a better wrestler..
big john studd also quit wwf due to Andre, not only that he quit wrestling altogether!!
stan Hansen is legally blind without his glasses! Apparently the only way he knew if he was hitting someone was by actually hitting them!! A lot of major injuries have been linked to Hansen (sammartinos broken neck and vaders popped eye are just two!).
No one really knows what caused the hatred between the British bulldogs (dynamite apparently won't even say his cousins name), but it's thought that it has something to do with Davy boy trademarking the bulldogs name and not allowing dynamite to use it..
the British bulldogs vs hart foundation feud were all family members (Davey boy being related to Bret and dynamite, dynamite linked to neidhart, and Bret linked with all 3).
Not sure where I read it, but once read that barbarian was one of the few who could body slam Andre the giant WITHOUT help from the giant..
In the ic royal rumble match between Shawn michaels and Marty Jannety (who was fired next day), Jannety runs shoulder first into a ring post.. Seconds later he's writhing about and holding his shoulder..... Only problem, it ain't the one he hit the post with!
Dino bravo was killed by Canadian mafia (something about illegal cigarettes)..
