Supermann #6/1970

In "En Supermann på to tonn!", Superman is honored with the sacred scarlet nectar by an alien race after helping irrigate their world—only to find the ancient drink has turned toxic. Though his invulnerability shields him from death, the reaction causes an unexpected and dangerous weight gain, testing his strength and wits as he struggles to stay grounded. With Lois Lane and General Dawes watching closely, and the mysterious Stros adding to the tension, Superman must find a way to reverse the effects before he becomes too heavy to move.
