Tombstone

L.Thompson Lincoln is the villain Tombstone, and the crime boss who goes by the name of The Big Man.

Big Man Of Crime
Little is known about Tombstone's past. It is known that after Frederick Foswell exposed Silvio Manfredi's(AKA Silvermane) criminal activities and the FBI took him to jail twelve years ago. Tombstone somehow took control of Silvermane's empire, thus becoming The Big Man- the biggest crime lord in New York City and he has run the criminal actions in the city since that time. At some point Hammerhead began working for Tombstone.

Spider-Man's Interference
Tombstone's operations were being ruined by Spider-Man, who was taking down many of Tombstone's criminal underlings. When Tombstone heard rumors of the webslinger, he had Hammerhead investigate the matter proper to make sure his criminal associates were sincere. After he saw a live video of Spider-Man defeating Flint Marko and Alex O'Hirn, he summoned The Enforcers and ordered them to squash Spider-Man. The Enforcers however, failed to complete their task, and Fancy Dan and Ox were arrested. ("Survival of the Fittest")

Making Super-villains
Norman Osborn tipped off The Big Man about a TRICORP shipment that was carrying a pair of vibro-shock units, and a protective suit. Tombstone and Hammerhead sent Montana and his men to steal that shipment, Hammerhead ordered Montana to don the suit and become Shocker. But Shocker once again failed to defeat Spider-Man, so Tombstone working through Hammerhead made a deal with Norman Osborn. Tombstone noticed that when Spider-man engages in battles with the likes of Vulture, Lizard and Shocker, he is too busy to interfere with The Big Man's empire. So he asked Norman Osborn to create Super-villains to distract Spider-Man. Norman agreed since he would gain huge profit by making Super-villains for Big Man. ("Market Forces")

Role in Ultima
In Ultima, Tombstone is primarily a neutral antagonist. Although he is ruthless and cold, he knows better than to ally himself with the dangerous wackos known as the Organization, preferring to stay in New York as the Big Man and fight the Society on his own accord.
