Caraprison

Caraprison is an alien from the series KrisTen, and is one of the aliens that Kristen can first transform into.

Abilities
Caraprison is gigantic. At more 40 feet tall, this is one of the largest aliens available for Kristan to turn into. It is able to both fold back its sharp teeth and detach/stretch its jaw to the point of being as tall as its whole body, allowing it to swallow whole just about anything. Once inside its body, the swallowed creature or thing is almost completely unable to escape. Its bubble like body is nearly indestructible from the inside, making breaking out impossible. Also, its mouth acts like a valve that can only be opened in the opposite direction consciously. It can also roll into a ball and preform a charging attack much like Cannonbolt, only for shorter distances and with less momentum.

Weaknesses
Unfortunately, besides the rolling attack, Caraprison is pretty much useless for offense. Its strength, although much, much higher than a human's, is below average relative to its size. Its claws are weak and useless for pinching. Its feet are small and its underbelly is delicate, which puts crushing things with pure body weight out of the question in most cases. If it has a prisoner inside of it and tries to roll around, the way that its energy transfers from keeping the walls strong to pushing itself forward gives its captive a chance to escape. It has no real way of harming whatever's inside of it, making it better for stalling.
