Expect The Worst.

Tanc830,428,723C saw that he was agitated but he chuckled. "Things aren't so bad. They might not apprehend you forcefully. Not everything has to be violent. We are the Supreme Beasts. We invade and plunder, steal, and enslave regularly but we rarely fight amongst ourselves. They will definitely approach you and they might just request to work together with you or examine your concept thoroughly. There's no need for violence. You might even be able to use this opportunity to benefit the whole Supreme Alliance and gain a lot of benefits from it."

That didn't assuage his fears. There is no way that he will allow someone to examine his concept thoroughly. That means he will open himself up to them so they can examine his existence. They will surely find the soul sphere then and any other secrets that they can see. He would rather they kill him than allow them to examine him.
