Suction-cups built into Tarantula's shoes allow him to cling to smooth walls and ceilings with Feeble ability; he can hang almost indefinitely, and move at one-half the speed he can normally walk. He can take only himself, carrying no significant extra weight.

The All-Star Squadron
Intrigued by the costumed crimefighters who had begun appearing in the late 1930s, best-selling mystery writer Jonathan Law began doing research for a non-fiction book about such "mystery-men." In the course of his research, Law interviewed Dian Belmont in the summer of 1941 about her association with the original Sandman. Belmont gave Law a sketch of a new costume she had designed for the Sandman which she doubted he would ever wear. After having written about crimefighting for years, Law decided to become a costumed crimefighter himself and decided to wear the costume in his mystery-man role.
Inspired by his pet tarantula, Law had decided to take the name Tarantula and, in keeping with this spider theme, devised a "web-gun" and suction discs for his boots that would enable him to walk up walls. He entrusted his loyal housekeeper Olga with the secret of his double identity.
A few days after Law's meeting with Belmont, Olga finished making the costume. That night, since the Sandman was out of town, Belmont donned his original costume to investigate a case of sabotage, only to be killed by a Nazi agent. Tarantula then attacked the Nazi agents, and was joined by the Sandman, who was wearing a costume based on Belmont's sketch. Together, they overcame the saboteurs.
Tarantula made his first public appearance soon afterwards when he defeated thieves who had robbed an audience at a Broadway theater. Reporting the incident, a radio announcer referred to the new hero as both a "Tarantula" and a "Spider Man!"
Tarantula joined the wartime All-Star Squadron, and soon afterwards adopted a new costume, feeling that Belmont had intended hers for the Sandman. Law also continued doing research for his book on mystery-men.
Tarantula's whereabouts and activities after 1942 are unknown, but his book on mystery-men, Altered Egos, was published in the 1960s.
