the cosmic treadmill is such a smart alternative to rebuilding the destroyed time-sphere. like besides the fact Bio-Ship can time travel now, which is sweet as hell, it also means no one can just steal her and go hopping through time. the treadmill presumably needs a speedster to work AT ALL, and probably only one that can run at Barry and Bart levels of speed. it's basically thief-proof, which i imagine the Legion would appreciate after Lor-Zod up and stole a time-sphere no prob
bio-ship the time machine what an upgrade <3 but don’t krytonians like dru-zod and lor-zod have all their powers under a yellow son? that would include super speed, meaning it would be possible for it to be stolen by like…an evil speedster OR an evil kryptonian like lor-zod. kryptonians aren’t AS fast as barry/wally/bart but they’re pretty close and could probably get the treadmill working. but honestly i doubt any of this will get that complex…i don’t think grandon are going that route….
