Sweet mother! All the heroes are being taken!

On a side note, here's a handy link for reference;

Bullseye
A notorious bandit hailing either from Ireland, Northern Ireland, or New Ireland. He is rather fond of throwing things dead center (i.e. knives) and is considered to be a headache for every law enforcement agency in the world, with the exception of Irish police forces where he passes himself as a super-hero in those cities (i.e. Boston, Cork, Limerick, etc.). He has been hired out by Kingpin and has been thrown against Daredevil, Luke Cage, and so on down the list. He is described as somewhat crazy. Most unfortunately, he was captured by Luke Cage in one of the numerous incidents involving the "Ace Attorney" (as well as Karen Page/Black Widow) and has been thrown in prison.
UPDATE: He has since escaped by unknown means. He can be spotted by his black leotard with a bullseye on his forehead or by a black leather jacket. Bullseye does go by very common Irish names and has the tendency to hang around in Irish cities due to the above tendency to "protect" them. Any non-Irish law enforcement agencies are warned to bring SHIELD/Stark Industries representatives.
Bloody Mary
aka Typhoid Mary
Considered to be the most catastrophic of Kingpin's own nefarious deeds in contesting the breath of New York with Daredevil, Typhoid Mary was once a member of the infamous Hellfire Club Brothel in Brooklyn, and nabbed when she illustrated an uncanny knack of super strength and psychic blasts. Many medical professionals attribute this to one of the numerous fights involving brothels and point out that she has displayed overt split personality problems. Her past escapades have proven that she is a worthy opponent of any and all super heroes that cross her path. However, this came to an end due to the Kingpin's attempt in hijacking the law (see; Murdock v. Kingpin) with the partnership of Luke Cage/Dakota North/Venom (iii) sending her to a "safe mental facility".
As of late, Typhoid Mary has been cured, and has been going by the name of Mary White on the soap opera "West Broadstreet". She has shown no symptoms of her previous illness and several statements have been issued that she is to not be trifled with on her past history.
Kingpin
A crime-lord and war-lord of the highest extreme. Based in Newark, New Jersey, Kingpin is known for his brute physical strength that only has been matched by the Hulk and other super strength heroes. He has no super powers but is attributed to the brutal death of his predecessor, Harry Blount ("the Owl"), the entire Brooklyn Syndicate, the Chicago branch of HYDRA, the the creation of the Sinister Six (the third incarnation), the ascendancy of Hammerhead, Silvermain, Typhoid Mary, the attempted murder of J. Jonah Jameson, the assault on James Jameson, the instigator of the Osbourne/Stark rivalry (never proven), the brazen hijacking of one SHIELD carrier (disputed), and so on.
Kingpin is described as a very large black man, bald, and fond of designer suits. He always carries a cigar and cane (for show). He is responsible for many deaths and served time. Many state that the Kingpin is untouchable and SHIELD regards him as Enemy No. 1, if they had diversified into the domestic scene.
Osbourne Technologies
Rival to Stark Industries. They are not highly regarded by the current Administration nor anyone else for that matter. They have been attributed to several deaths and creations of super villains. It is currently being run by Tombstone, a known affiliate of Daredevil, and is in a middle of a "feud" involving USAgent/Luke Cage/Kingpin/SHIELD.
Sabertooth
aka Victor Creed
His criminal history is too long to account here.
He is described as a "poor-man's" version of Wolverine (Herald of Galactus) to the point that if he were to gain power as a Herald, the world would be doomed. Thankfully, he is serving with the X-men, but no-one knows when he will break that status.
His uniform is either shades of yellow with bits of fur on the shoulders/ends of his limbs with clawed gloves (it is not known if the claws are from his actual hands) or the current solid yellow leotard with black shoulder pads.
Sabertooth is prohibited from ever entering Canada. He does have a daughter by the name of Clarice Sterling (Blink). More about her can be detailed in her biography.
