They grow back. Rarely they grow a new intergalactic star fish.
Not like star fish on Earth where as long as the ring in the middle is attached, a whole new star fish can grow from a single leg?
I just send the Justice League after the new baby tyrant. They feel good about beating up on defenseless star fish.
Just call for a mew. They love to fight, feel no pitty, no remorse, no fear, can't be bargained with, can't be reasoned with, and absolutely will not stop until they've won. They won't attack defenseless star fish either. No sport. And no. They've never fought a terminator and don't know SkyNet but they'd like to meet them. For battle of course.
