"Unknown energy impulse detected." The mountain's computer said. "Computer! Lock down base!" Nightwing shouted as he, Robin, and Beast Boy got ready for a fight. Then a machine came out of nowhere and opened up revealing a boy inside.

He slowly climbed out looking around with - wonder? "Well I think we found out unknown energy impulse." Beast Boy said. The boy seemed to not notice them at all, to busy looking around.

Nightwing and Robin were to busy analyzing the boy to respond. After looking around, the boy's eyes widened. Then he started jumping up and down. "It worked!" He cried, "It really worked!"

Then Nightwing decided to do something and said, "Who are you?" He doubted the boy would respond, but when he turned around, the boy cringed as if just noticing them for the first time.

He then said, "Sorry to bother you, but I've got people to see, things to do, you know, the usual." Then sped off.

The trio of heroes wasn't exactly sure what to do, but then they suddenly heard a scream.

Rushing to the sound, they found the speedster, (cause that's what he turned out to be,) standing in front of Blue Beetle. He was looking at him with wide eyes, and appeared to be having a panic attack.

Nightwing put his escrima sticks away, and cautiously approached the speedster. When he offered no sign of resistance, Nightwing reached out, putting a hand in his shoulder, and said, "Blue Beetle is a hero, there's no reason to be scared."

Then the speedster looked at him strange, and something akin to realIzation crossed his face, and he briefly muttered, "The past, you're in the past."

He then realized how close he was to Nightwing, and backed away, abstracting himself from the vigilantes grip. "Who are you?" Beast Boy asked, and Nightwing said, "It's important we know who you are."

At this, the boy smirked, obviously coming down from his panic attack. "Well I guess it would only be fair, since I know who you are, Dick Grayson." Nightwing went still and Robin's mouth dropped open.

"My name is Inertia."

Author's note:

Sorry the chapter is so short, it was late and I felt I needed to post something. This is basically a fic where Thad accidentally came back to the past instead of Bart with a few changes in how things turn out because him and Bart are, well, opposites.

I am considering doing a fic after this with Bart already in the past, and Thad shows up. Please tell me if you are interested.

Also, please comment and tell me if you enjoyed this and want more! I am a first time writer and need some advice. Will update again soon!
