Comment(s):
- The Superman robot is crushed in the 10 mile depth of the ocean. Not that there's any known location that gets 10 miles deep, but this would be 1,593 atmospheres.
- Red Kryptonite radiation is stated to be stronger than that of green kryptonite, with lead being unable to stop it, though this is disproven in other appearances.
- The three flashbacks with Superman succumbing to red kryptonite are still being researched. These involve Superman sleepwalking and wrecking the Fortress of Solitude, Superman losing control of his heat vision, and Superman hallucinating, imperiling a ship.
