The Turtles brought to the present have helped bring their present-day counterparts back to full-health and must be sent back before they cease to exist. Meanwhile, Dregg has brought his invasion fleet to Earth.
Tropes
- Temporal Paradox: Having eight Turtles from two different points in time causes a time paradox that would cause all eight of them to cease to exist should they not return to their proper moments in time under three hours.
- Weak-Willed: Krang claims that Dregg's bat-men have rather limited brain-power compared to most, hence why Krang was able to hypnotize one of them so easily.
