Animal Antipathy

Achilles Heel: Animal Antipathy by Senator Cybus

Animals, virtually all animals, hate the Mega Hero. All mammals, birds, reptiles, amphibians and fish react very badly to his presence. Any animal that detects the character will immediately attack, actually fighting to the death if not restrained!
The animal in question will also make an ungodly din while attacking, barking, roaring or screeching as befits its nature, and alerting everyone in the vicinity to the presence of the superbeing. This makes stealth problematic at best...
Intelligent mutant animals and superbeings that depend on a connection to/affinity with the animal kingdom for their powers (Animal Abilities/Metamorphosis, Beastmaster, Feral, etc) are also affected. While not driven to the same extremes of aggression, they instinctively dislike the character: reduce M.A. by 50% when interacting with such beings.
