Marc can also transform his body and clothes into mist - as well as being useful for infiltration and defense, this also allows him to swiftly heal most injuries, which tend to vanish after transforming to mist and back. While he could at first use this ability at will, when the Gen-Factor was flushed from his system, his ability to use this power was restricted to only once or twice a day. However, his energy whips had doubled in power as a result. When first exposed to the Gen-Factor, Marc had extensive psionic powers including telepathy and telekinesis, but these powers waned over the years and even completely disappeared together with the Gen-Factor removed from his system.
