This looks like a job for Superboy!

Did I reach Oa? The last thing I remember was Superman grabbing me and flying me somewhere. But it doesn't matter. I am finally back home. I decimated the Teen Titans without even trying, and even the Justice League couldn't stop me. I don't remember this giant castle, but I haven't seen my home in a long time.

I..I don't know what to do first. I should probably patrol the area and see if anyone needs help.
