Re: Nah. He sounds just like a leaching parasite. Nothing more.
"Don't you mean leeching? The imagery evoked by "leaching" is just a little too gruesome for my taste ..."
Leaching: leaking of chemical components of something into a surrounding liquid. Example: Storing drink for long periods in lead-crystal containers causes leaching of the lead from the glass(1) into the drink.
Leeching: that which is done by leeches, by which, in context, we usually mean the hematophagous varieties, the ones that suck blood.

(1) Although we call it "crystal", it's actually glass. https://en.wikipedia.org/wiki/Lead_glass
