Fortress, aka, Nicholas Fort, was a member of the Silver Seven until he betrayed and murdered his teammates in order to fuel Douglas Pierce’s political ambitions and his own lust for power - as Pierce moved into political circles, Fort took over more and more of the overtly criminal organizations Pierce had set up to destroy of muzzle his rivals.
Fortress joined the Silver Seven in 1983 at the age of 20 and quickly became one of it’s most popular members. Appealing and photogenic, the young hero was often the ‘face’ of the team to the media and the press. Poised, cool under pressure, and with a glib tongue, Fortress kept the Silver Seven in the limelight for years. His skill on the battlefield was also impressive. Fort was born a mutant and at 14 his powers began to manifest. He gained a mild degree of super-strength but his greatest power was his invulnerability: he is the highest-rated non-cosmic entity in that category. He is on record as having lived through a direct fusion explosion, being thrown through the heart of a star, and having shrugged off N-Pulse’s disintegration beams.
When news broke of Fortress’s betrayal, many denied it even though he confessed to the crime; such was his popularity with the people of Oakland. Even when his dealings with Pierce were later revealed in full, many claimed it was a smear campaign against him.
Nicholas Fort is beleived to currently reside on the private island of Ikros in the Agean Sea, home of the Fort family and heart of their shipping empire, sheltered by his family despite demands by ATLAS that he be turned over to them for criminal prosecution. The Greek government’s strained relations with ATLAS at present probably contributes a great deal to the lack of official national cooperation. Fort is currently wanted in the US and Canada for 147 counts of criminal conspiracy and violation of various RICO statutes, and wanted for questioning in at least 6 murders (his four teammates in 1988, Monica Sales in 2000 and Oakland city official Howard Parks in 2003).
