pardon me for getting in late, these probably aren't as funny seeing as how I don't focus on individual characters as much as the overall storyline (DS9, of all the ST franchise, was the only one to have a consistent story that led places... true some of them were lame, bleached-background, vaseline-covered-camera-lens places, but not all of them
) enjoy
Odonium: bestows on it's user the power to be super bland and anal retentive?
side effects include melting, pooling, puddling, and strong urges to 'link' with other Odonium users
O'Brienatilum: instantly makes one competent in the repair of federation technology, with only a minor side-effect of war-flashback PTSD and an overwhelming urge to play darts with swarthy smart-aleck doctors
Kerzonurubaum: changes the users gender, side effects include freckles, sexual promiscuity, and awkward relationships with old friends who are now possible suitors
Quarkygen: grants the ability to imperceptibly water down drinks, cheat others of their latinum, and generally be a total **** to everyone including your own brother, while suffering no ill consequences (of course, you never do -win- but you never really out-and-out lose either... mediocrity is the essence of Quarkygen)
Worfalidate: grants the user super strength, courage, and a forehead that can juice oranges (neat!) side effects include a penchant for plums and wearing robot-track-tread around one's chest as well as an increased sensitivity to jokes about ones parents.
