Bad Guys of the '80s.

Wings Hauser as Ramrod in Vice Squad (1982)

Gene Simmons as Velvet von Ragnar in Never Too Young to Die (1986)

The greatest decade for movie villains imo.

Frank Booth should be in there somewhere.

Oh yeah, along with Bennett (Commando), Richter (Total Recall) and Robert G. Durant (Darkman) he surely was among of those few "henchmen" or second in command I guess, who just completely overshadowed the main villain in the 80s and early 90s action films. 
While Boddicker may not look like much of a "physical" threat, he is as you say, such a nasty piece of work, and I think that he kind of look so "normal", it just makes him the more menacing, than just another "classic" bad guy, with evil scar on his face, or something like that.

Clarence was a truly disturbing and evil guy, and they sure do not make that kind of villains any more.

The Death Wish series, specially when it hit the 80s, had its own unique world of some very colorful and memorable bad guys, just not the main villain, there were so many hilarious baddies, but few seems to be more loved by the fans than that of Manny Fraker (Gavan O'Herlihy) from Death Wish 3 (1985).

Whenever he seemed to run out of bad guys, he just orderer a whole bunch of thugs through his "connection", just like if he was ordering a pizza, and before you know it, there streets are filled with scumbags going completely berserk, dancing and jumping on cars, and beating up old people, and, yeah, just even more gunfodder for the always trigger happy Paul Kersey to get rid off.

So much fun and over-the-top acting going on, just within less than two minutes. You got the hilarious "toilet plunger" thug, who waves proudly of his new found and very menacing "weapon" into the air, and the whole ridiculous campy bad guy part, who tries to "beg" for some money outside a store, while Bronson sure replies with one hell of a powerful suckerpunch! 
Damn, this one is masterpiece of movie making, so much fun and always noticing new and very funny things, whenever I re-watch it.

I'm surprised and disappointed that this thread has gone on for so long without anyone mentioning Bolo Yeung from Bloodsport. I prefer him even to Ivan Drago.

A sidenote: Chuck Norris movies never have memorable villains (one could say that they never have memorable heroes either)

After the extremely grim Death Wish II, along comes Death Wish 3 that is sharp in contrast; it's over-the-top, exaggerated, ridiculous, and campy...and a whole lot of irresistible fun! Gavan O'Herlihy does a fine job as the head punk Fraker. Just love it when he delivers the line "He's on my turf! I'll take care of him." Yet it's also disturbing when he tells Bronson he's going to kill a little old lady just for fun and to catch it on the 6 o' clock news.

The thing is that the 80s had so many great and memorable villains, and one will always end up "missing" out on a few of the classics bad guys, but surely Bolo is up there among the all time final bosses, no doubt about that. I think he is part of the reason to why Bloodsport (1988) is my favorite Van Damme film, and that is pretty much down to how awesome Yeung delivered his evil character to the screen, along with all these hilarious facial expressions and sadistic way of doing a bit of mindgames with his opponents.

Was quite "shocked" the heavy hitting biker friend (Donald Gibb) Ray almost took him out with a brutal blow, but I guess his naive way of celebrating to early, instead of going for the "kill", ruined what would surely be the end of Bolo, who of course was the superior fighter, but even he looked quite stunned for a few seconds afterwards, and yeah, I love this film so much, classic 80 and early 90s entertainment.

I think you might be a bit too "hard" on Chuck, as I do believe Richard Lynch is, well maybe not all up there among the all time 80s great villains, but he sure was one ruthless bastard as Rostov in Invasion U.S.A. (1985), that's for sure:
