One of the guardians sacreficed himself to destroy the menace Superboy-prime. However instead of killing him he transports him in a different multiverse and different universe where Prime has become a full grown adult and has gained a black-Superman like suit. As he floats into space he slowly came across the Sun and as he got closer he waked up.

"Where...Where am I and...I'm an adult ?" Prime asked surprised then he saw a blue planet that appearred like Earth. Prime then grinned at began flying at the planet.

"That egg-headed idiot actually thought he could get ride of me so easily. Nothing can destroy me...Nothing ! Those losers are so dead when I get back!" Prime said with a sinister smile as he arrived on the Earth. Once he entered the planet he notices something very...very different. It wasn't Earth-2 or any Earth he's seen. He then decides to explore this area as he was exploring then using his super hearing, he heard voices underground and using his x-ray vision he was surprised at what he saw. There were aliens of different species underground doing all kinds of stuff Prime then used to fly above still using his x-ray seeing all kinds of stuff happening then saw 3 aliens on floating bikes being chased by a truck.

"I got this Rook" Ben said as he transformed into XLR8 and after the the crooks began shooting at the speedy alien they all missed, XLR8 took down each and every one of them with ease then the truck arrived and Rook handcuffed all of them.

"I must say that was quite impressive Tennesyn" Rook said as he finished handcuffing the last one.

"What did you expect after all I saved the universe many times" Ben said as he transformed back to normal. However all of them were unaware that they were being watched by the kryptonian who overheard his speech and was far from pleased about this.

"Saved the universe huh ? Well then well see who's the real hero after I destroy you. No after I destroy this planet and this universe, after all non of them are real...I'm the only real person,I'm the only real hero around here !" Superman Prime yelled as his eyes turned red and shot heat beams out of his eyes but instead hitting Ben directly he shot his beams all over the underground city destroying some buildings and killing the inhabitents.

"What the !" Ben yelled as he and Rook saw two red beams destroying everything. Ben hit his Omnitrix transformed into Grasshopper then grabbed Rook and the crocks and jumped away just in time to avoid the beams as they destroyed the truck.

"My truck !" Rook yelled as the beams began coming close to them but Grasshopper once again leaped away from them. Then they went in a cave and leaved the crooks there.

"We need to find out what's causing this" Rook said as he got his weapon,Grasshopper then transformed back to Ben who transformed into Aerodactyl grabbed Rook and flew up.

Prime was still continuing on destroying until he saw and pterosaur-like creature carreing another more human-like creature who had a strange looking gun.

"Hey ! what do you think your doing !?" Asked the pterosaur-like creature

"Just getting rid of this pathetic DC wannabe universe. Let me guess your a corrupt superhero who feels the need to try and stop me. Well I've dealt with people like you before and I will not have stupid copy cats" Prime yelled as he shot his heat vision at Ben and Rook who barely avoided the insane kryptonian's attack.

"I don't know what your talking about or what your problem is...but you need to be stopped right now !" Aerodactyl said as he shot energy attacks from his mouth along with Rook who fired at Prime. But their attacks had no effect on the kryptonian.

"Really ? Is that the best you got ?" Prime laughed as he shot his heat vision again.
