Manduu was an alien giant from Marvel comics, an enemy of Olympus (home of the Greek gods) and the Thing.


Krokarr, Manduu, and Y'Androgg were all members of a race of giants which came from a star located in the same dimension as Olympus. The trio stealthily invaded Olympus while its gods were suffering from the after-effects of over-celebration during the Spring Festival. The giants banished most of the gods, binding Zeus in the Tower of the Sun, and severely devastated much of Olympus.

The Thing and Hercules invaded the Tower of the Sun and rescued Zeus, but Manduu interrupted them before they could escape. However, the Thing tripped him up and Hercules knocked him into the Tower's flame pit.
