PARAGON, leader of The Sentinels of Justice and YANKEE GIRL, popular Vault Heroine present the support cast of the FEMFORCE comic book. Paragon has several heroes under his leadership that have played a big role in many of the FemForce adventures. And Yankee Girl is one of the most frequently seen characters from The Vault. Paragon himself is not only the oldest AC Comics character, that's both in real and fictional time, but he has had his own AC Comics titles in the past and is currently the love interest of Ms. Victory. As a companion character to Ms. Victory, his strengths also lie in his leadership, his mental capabilities, power of flight and strength. Yankee Girl, the reluctant heroine, finds dealing with her powers and with the 1990's, more than she can handle. In the graphic novel entitled TIME STORM, the reader is witness to Yankee Girl's potential as a heroine.

A prominent Sentinels member, the Scarlet Scorpion is the street-wise, macho type hero, a perfect (and frequent) companion for She-Cat. He doesn't have She-Cat's nine lives, but he has something else... the ability to recuperate from injury at a very fast rate, due to a cell-generation formula. When the need is for someone with savvy.... someone who can read the street people, the criminal mind and act fast... these two are ready.

Other Sentinels include Darkshade (with his ability to enter the dreams of others), The Avenger (a Vault Hero and Sentinel as well) and Videxx with his genius in communication and surveillance. And there are the dimension hopping heroes, Commando-D (or D-Man as he is known) and Astron (policeman from another dimension).

Dr. Weir's Vault of Heroes is a group who volunteered to be placed in stasis after their early careers ended to be called for duty at some time in the future when they might be needed.... and needed they were to combat the evil BLACK SHROUD. Called into action with Yankee Girl were Cat-Man and Kitten, The Avenger, Miss Masque, Rocketman and Jetgirl and many others. (For comic book historians, this represents the revival of many Golden-Age characters from companies long since out of business.)

Why are all these heroes needed? The FOES! The Black Shroud, The Shimmerer, Alizarin Crimson, Fem-Paragon, Darkfire, The Fearforce, Stella Stargaze, Lady Luger, Capricorn, etc. and those that are sometimes friend and sometimes foe... Garganta and Rad! In "The Yesterday Syndrome #1-3" The Shroud and The Shimmerer are engaged in battle with each other using the FEMFORCE as their pawns!
