The plant alien looks like a pod with purple roots. When the plant alien bloomed, it popped out of the ground and had one eye with a dark purple outline.
Powers and Abilities
The plant alien can use its vines as arms to grab victims and hold them above itself, in order to devour them. It can also shoot a burst of goo from its mouth. It can imprison people in container like structures and create clones of them, although without the real version's powers. It was also able to take the Ultimatrix from Ben.
Its weaknesses are fire and peanuts, causing it to shrivel up and die. It cannot create clones of people who have recently eaten peanuts.
