Swift Silver, the Defender of Alpine City. For more than a decade, Swift Silver, aka Rita Malena, has helped protect Alpine City from the criminal and villainous element that would see it corrupted. A champion of justice and honour, she has gained a massive following of fans and supporters.
It was in her early twenties that Swift Silver took up the mantle of Defender and Heroine. Although she had long known of her powers, she had hoped to lead a normal life. She had graduated high school and went off to college to study computer science. It was only when the Hellhound began to terrorize the city, leading his pack of demonic canines and demented gang members in a war against the police, that she realized that no one else could do what needed to be done. She quickly crafted a costume and, in a massive battle in the city’s main park that was recorded by news crews and broadcast for weeks, defeated the Hellhound using blasts of silver light.
The thrill of victory and adrenaline of battle was too much for her to resist, and she began to patrol the city on a nightly basis. She broke up gangs of robbers, traffickers, and dealers. She thwarted numerous plots. And, slowly, she built a reputation as she defeated any super villain foolish enough to enter her city. The Dragon, the Dark Mind, the Twisted King, the Hellhound, and numerous others have all been defeated by her. She stopped a villain disguised as the mayor, she broke up a ring peddling a mind control drug, stopped a demonic incursion, prevented an alien invasion, and has performed many other feats both large and small.
Swift Silver’s powers are centered around super-human speed and control of what she describes as ‘angelic light.’ The speed, which only works in darkness, allows her to move almost too fast to see. The light allows her to bathe herself in a protective shield, strike with explosive force, and project beams of energy. The light will protect her from almost any sort of attack, however when used offensively will only damage those she considers her enemy. It will not damage inanimate objects at all. She is capable of flight when she has her protective shield up, but finds it extremely draining.
Most normal humans can take only a single blow or blast from Swift Silver’s powers, though none have yet died as a result. The super-human can usually take ten or less such blows.
Swift Silver cannot break her word, if she does, the one she broke her word to gains an unnatural ability to influence her with his words. All of Swift Silver’s powers rely on a limited pool of energy that she draws from direct sunlight. When she runs out, she will no longer be able to use her powers until she has a chance to sunbathe again. Normally this isn’t an issue, but major battles at night or indoors, or inclement weather over multiple days, can result in her running low. To use her powers offensively, she must be able to use her hands. Either to punch, or to project a beam from the palm. Likewise, she can only attack what she can see.
The general idea I have is that Swift Silver is in her early to mid-thirties and at the height of her fame and success. She is largely undefeated, and has grown complacent and overconfident. This leads to her taking risks she shouldn’t, and her eventual defeat and capture.
