There are bound to be different opinions on this but I think the German suplex where a fighter clinches his opponent with a rear waist lock, then lifts him overhead and throws him down behind him, often resulting with the supplexed man landing on his head is the most dangerous. It could lead to complete permanent paralysis or death.
This suplex, sometimes called the belly to back suplex is far more dangerous than the belly to belly suplex.
