Artificial Body: Mimics are not subject to negative or positive energy. Thus cannot be healed or damages by it. However, their aberrant nature allow them to heal naturally at a alarming rate. They have fast healing equal to half their HDs (Minimum of 1). The fast healing is a (Supernatural) ability.
Construct Body: Immunity to poison, sleep effects, paralysis, stunning, disease, death effects, and necromancy effects. Not subject to critical hits, nonlethal damage, ability damage, ability drain, fatigue, exhaustion, or energy drain. A mimic do not need to eat, drink, sleep or breath.
Eternal Youth: Mimics do not age physically, however their mental abilities still improve. They do not die of old age.
Magical Lifeforce: Dispel magic and antimagic fields have a negative effect on mimics. When hit with any dispel magic, make a Will saving throw vs being knocked stunned for 1d4 rounds. An antimagic field incurs a save vs unconsciousness every round until they leave the area, and mage's disjunction becomes a save vs death.
Master Dependency: The mimic creator and master have total control over the mimic. As long as the mimic is within 1 mile of him he can target the mimic with dominate monster (last until dismissed). This ability can be used at will and offer no save to the mimic. Mimics are also dead loyal to their master, any attempt to make them turn against their master automatically fail (even with the use of powerful spells). This is a (Supernatural) ability.
