Vampiric Bite

Vampiric Bite (minor) by Senator Cybus

The character can deliver a powerful bite attack, and use it to feed upon opponents.
The super being can will his canine teeth to transform into sharp fangs: this uses up only one melee action, and reversion to normal is just as fast. Once this is done, the character’s bites will inflict 2D6 damage + P.S. bonus (if any).
Furthermore, the character can use these fangs to drain the blood of others, to nourish and heal himself. If the super being’s target is incapacitated, he can simply bite them and feed at his leisure. If used in combat, the character must first successfully grapple with his opponent, pinning them or placing them in a hold that puts them within biting distance. If the opponent cannot break free on their next action, the super being can sink his fangs into his helpless foe, and feed for as long as he can maintain the hold.
The super being can drain the maximum amount of blood allowed for his level (see Damage below) with every melee action he devotes to the act of feeding. S.D.C./Hit Points taken from an opponent in this way can be used to replace the character’s own lost S.D.C./Hit Points on a one-to-one basis, e.g. inflicting 6 damage with the bite allows the super being to instantly recover 6 S.D.C.
Alternatively, the hero can use the blood to nourish himself: the super being can comfortably go for 48 hours without food or drink by causing drain damage equal to ten times his experience level (10 at level one, 20 at level two, etc - the more powerful he gets, the more blood he needs).
If not in immediate need of healing or sustenance, the character can store a limited amount of blood: he can stockpile an amount of S.D.C. equal to 50 + 10 x the character’s experience level (60 at level one, 70 at level two, etc). This can be used to either repair injuries or provide nourishment as needed.

Note: The character is not a true vampire, and does not automatically possess the traditional abilities or weaknesses of such creatures, though the player may choose other powers that simulate them.

Range: Touch - close combat.

Damage: 2D6 + P.S. bonus from a bite attack. Blood drain causes 1D6 damage per level of experience.

Attacks Per Melee: A bite attack uses up one melee attack/action. Draining the maximum amount of blood also uses up just one melee attack/action.

Bonuses:

+1 to strike with a bite attack, plus any P.P. bonus.

The character's fangs have an A.R. of 7. If damaged, they will heal completely within 1D4 hours. Even if the teeth are removed entirely, they will grow back within 24 hours.

Limitations:

While the super being’s transformed teeth are unnaturally sharp and tough, they cannot penetrate natural or man-made armor with an A.R. of 10 or greater: even if the character has superhuman jaw muscles, there's only so much punishment his fangs can take before breaking.

The character cannot drain blood from inorganic, supernatural or energy-based beings. He can feed from the recently deceased, as long as the target has not been dead for more than an hour; any longer than that and the lifeless blood actually becomes toxic, causing the character 3D6 damage if he ingests it.

While draining an held opponent, the character is vulnerable to attacks from others; he is essentially defenseless for as long as he maintains his feeding hold.
