    Summary

    Using the powers of the Time Scepter, the Ultimate Drako sends Donatello to his own personal hell. However, he's not the only one. Leonardo finds himself in a dystopian world ruled by the Shredder's grandson, where his father and brothers are long dead. Well… almost all of them.

    Leo isn’t entirely sure what to make of the strange, hardened turtle who just so happens to share his brother's name, but it must be a coincidence. There's no way this turtle could be an older version of his goofy little brother. Right?

    Summary

    After spending some time harassing John Bishop's successor, keeping her from progressing with interdimensional experiments, a message is sent to Raphael (03) claiming that Agent Augustine has custody of his three brothers. Except Don is there watching the video message with him, and only one of the three mutant turtles shown on screen are related to them.

    (Summaries suck, this is a TMNT 2003 and ROTMNT crossover where faulty science grabbed the Rise siblings and brought them to the 2003 verse. Now the 2003 brothers have to rescue 2 of the Rise brothers, then find the remaining 3 siblings after. Augustine is a plot device villain OC. She's not given much focus.)
