Hydro-man
First Appeance: Amazing Spider-man #211
The Story: Morrie Bench became Hydro-Man when he was knocked into the water during the testing of a new under-water generator. An unlikely set of circumstances including the failure of the device and the presence of undersea volcanic gasses lead to a situation whence quote 'the energy conversion reaction within the device combines with the gasses in the water to form an energy for which there may never be a name' unquote. That is to say - a one-in-a-million situation which creates the super-villain under consideration. It's too extra-ordinary to try to explain, it's impossible to reproduce, and kids - for goodness sake don't try this at home in your bath-tub. OK? Morrie Bench was actually a labourer on the ship involved in the experiment - however when he discovers the nature of his powers, his natural unlawful temperment combines with a psychologically destabilising side-effect of the accident to create what is essentially a super-villian waiting to happen. Hydro-Man sets off for vengeance on Spider-Man, who coincidentally happened to be on-board the ship when this all started - and when he finds him, the scene is set for a battle-royal. Does Spider-Man have what it takes to mop-up Hydro_man, or will the eensy-weensy spider get washed down the drain? A note here also about Sadie. Sadie is a woman of loose morals who is approaching the later years of her life. She apparently knows Morrie Bench before his transformation - and makes an appearance in Amazing #212. In Amazing #217/#218 we see both Sand-Man and Hydro-Man vying for her affections, in an amusing little story which ends in a climactic (and rather sublime) melodramatic finish.
