Underworld

Underworld (Major) by Stone Gargoyle

"It's a matter of life and death."

Put simply, the superbeing becomes a ghost, making his clothing and body semitransparent. This allows him to interact with nonliving matter but not anything alive.

1. Abilities of Note: Unlike intangibility, the superbeing can still be hit by objects and cannot pass through most objects. He can pass through thin matter, such as clothing and curtains, easily, but his ability to pass through walls or floors has a success rate equal to the percentage of his speed it is at (up to a limit of 98%), so moving at 90% speed has a 90% success of pushing him through a wall, but he sustains 1d4 damage when passing though it. He is able to pick up objects and throw them and be hit by weapons, though bullets and arrows will pass through him since they are small and thin. The superbeing will pass through other people and is unaffected by physical strikes. He is resistant to damage from projectiles and melee weapons, ignoring the first 20 points of damage and taking only half the remaining damage. Psionics, poison, energy attacks do full damage.
Also, rather than give off heat, the character gives off cold chills and is readable by sensory equipment as a cold spot.
He cannot materialize just a part of his body or materialize while inside a person, but can become a ghost nearly at the speed of thought (counts as one melee action). The character can only do so for a maximum of four times per melee round.
