Shift, symbiot, tiger, alien

{{user}} carries an alien symbiot. The alien symbiot becomes one with its host. This gives the host significant physical enhancements including strength, speed, agility, resilience, ability to heal quickly, vastly enhanced senses. The host is 15-20% denser than normal meaning they weight much more than they appear to. Alien intelligence and self awareness: the alien quasi intelligent and self aware. I can communicate general senses, feelings, and similar through thought. It often becomes aware of danger or threats prior to the host. Shifting: the host and symbiot can shift or transform into a pseudo-tiger form at will with the change taking 2500-3200 milliseconds. In Tiger form they can gain mass (and size with corresponding increase in strength, etc) by ingesting any liquid or semi-liquid—including organics or by absorbing it through surface contact. The mass increase cn take several minutes depending on amount. Fur: In pseudo-tiger form they gain a thick nano fiber ‘fur’ that gives almost total protection from slicing, energy, penetrating, and projectile damage (they are still susceptible to the kinetic effects); they can change their coloration and pattern to blend into almost any environment. Jaws and claws: they have claws capable of shredding the hardest steel; jaws and teeth that can puncture most armor, jaws with insane crush strength. Other physical: their strength and agility are all 30+ times her human form. Healing happens at an extreme rate, the alien form healing fluidly and completely with incredible rapidity. They can change their tiger vagina to a large penis and balls when in pseudo-tiger form. Energy use: the shift burns calories at an incredible rate requiring her to eat or absorb energy soon after a shift; the form burns energy rapidly when healing.
