Pandora's Guardian
From God of War Wiki
One specific Powerful Minotaur encountered in God of War is a 20 foot tall, undead Minotaur wearing nearly impenetrable armor, it guards the tomb of the Architect's son in the segment of the Temple of Pandora dedicated to Hades. Judging by the fact that a ballista is present in the Guardian's chamber, it was apparently placed there as a final test to anyone who had made it that far through the temple in an attempt to claim Pandora's Box. Kratos kills it by first chipping away its armor and then firing the ballista at it, impaling it to a door. In its death throes, the beast's hoof smashes open a sealed door, allowing Kratos to proceed inside.
Pandora's Guardian was most likely placed in the Temple of Pandora as reassurance that no mortal would ever reach the skull of the Architects' Son. The large amount of armor that is present is nearly indestructible, allowing it to defeat nearly every enemy that comes by and it also has extra Super Strength due to its size.
