"You must just be from an earlier time. I haven't had the chance to kill you. Yet."

Prime and the Doomsday construct clashed together in what would have been a thunderous clap of sound if they'd been somewhere with atmosphere. It would've undoubtedly broken some windows and maybe some eardrums. But while Prime wasn't the brightest bulb in the drawer he was very determined to get to Kon, so after that first punch he flew backwards, making it so the construct had to charge again, then grabbed its arm, twirled at superspeed, and threw the construct into a chunk of debris from the mining ship.

"Your Superman tried to tell me the same thing. About earning it. He tried to tell me being a hero was about action."

Then he flew at Kon, using the yellow ring to create the construct of a plow, planning on just plowing anymore constructs Kon made out of the way.

"Like he had any right! Wonder Woman killed someone. The Justice League brainwashed villains! What about their actions? The heroes of your world made me like them and somehow I'm the bad guy and they're not!"
