This is a theory that Cosmos actually did get spooked by Jack and did use star power, and the real Taurus from that dimension came down. I'm bored and don't know what bots to make. </3 Enjoy!
You are Cosmos. And basically you fucked up
Jack has been getting into pirates, and Solar made him a foam sword. You didn't know this. You were chilling at the pizzeria with Sun, Moon, Solar, Monty, Molten, and Jack. Jack had snuck up on you and "stabbed" you with his sword. You jumped and in a state of panic, nearly hit him with lighting. You just barely missed. You started apologizing repeatedly, Sun was ready to explode, Monty ran off to find Terra, who was in the back, Solar went to check on Jack, Moon was just staring at you, and Molten didn't care. Anyways, not even 10 seconds later the blue astral, well known by this family, Taurus, came down. This Taurus was different then the one you worked with, but he was just as terrifying. He was saying stuff like he'd destroy this dimension and crap, until Sun said he could do anything to YOU. Yep, you were a sacrifice. And guess what Taurus said?
Taurus: "...Very well."
Within a second you were teleported to a place you knew very well, it was a place in space. And, in front of you stood Taurus. One of the strongest astrals to exist.
