Pusher

Pusher is a somewhat obscure Marvel comics super-villain who appeared in the 1970s as an enemy of Ka-Zar, a lesser known Marvel hero - he has not been seen in the modern era and thus serves as one of many villains who are somewhat lost to time in the very diverse and often confusing tales of superhero comics.

History
Pusher was a lieutenant of Harlem crime-lord, “Boss” Morgan. While his daily duties were largely undisclosed his code-name made it obvious that he was largely in charge of expanding drugs into new turf.

Pusher was a strict boss and demanded physical perfection from his gang, teaching the close combat techniques and even going as far as making a gym his headquarters, he was a tyrant in this regard and this (combined with his drug dealing) contributed further to his code-name of "Pusher".

The Pusher's gang came into conflict with Ka-Zar and Zabu when they were beating up a freelancer drug dealer who had entered their turf, despite Ka-Zar scaring them off one of the thugs managed to knife the freelancer and killed him before fleeing.

Shortly after this murder, Pusher agents attempted to kidnap Dr. Wilma Calvin, the mentor of Dr. Bobbi Morse die to the fact AIM agent Gemini was offering a vast sum for her in order to obtain her Super-Soldier serum research.

Once again Ka-Zar foiled Pusher's gang and located the gangster's headquarters - the ensuing battle rocked the building to its core and indeed beyond, collapsing the entering thing and separating the fighters (who both survived and swore to fight again).

The Pusher would surface again after he took down an undercover narcotics NYPD officer, during this time he was also becoming angry with one of his men named "Vinnie", who was actually Dr. Calvin's son but due to Vinnie refusing to back down Pusher decided to use him as bait to lure Ka-Zar into a trap.

While Ka-Zar was interrogating Vinnie Pusher ambushed him, now equipped with a strength-amplifying vest and attempted to inject Ka-Zar with an overdose of drugs but was distracted when Vinnie tried to stop the murder - this resulted in Pusher beating Vinnie to a pulp.

Enraged, Ka-Zar picked up the strength to fight back with more zeal than ever and defeated Pusher, leaving him alive for the police to arrest while he rushed Vinnie to the hospital just in time to save his life.

Pusher was last seen in jail, perplexed by hearing police officer Damien Link briefly speak with the same voice as the AIM agent who had hired him.
