Super power krypton gold [Comprehensive]

I knew with just one glance that this would be the most dangerous supernatural battle in my life.

In front of me is a formidable enemy who is brave and good at fighting, and cooperates seamlessly. There are only two people beside me, the Cave King and Hotaru.And behind me, there are unarmed and innocent citizens, and ordinary police officers with guns in their hands but useless.

For them, I cannot take a step back.

"...Avenger. Prepare to fight."
