Superman vs Inertron
Test of strength
Superman tests his strength and designs a solid 12X12 ft block of Inertron with the exception of the hollow center, which is moulded to accommodate his exact body size in case he should ever go rogue. He enters, lies down, the chamber locks and is magnetically bonded holding him in place.
Scenario 1
He enters without sun dipping. Can he break out using all of his strength?
Scenario 2
He enters after bathing in sunlight. Can he break out using all of his OWAW level strength?
