What was Hades' special talent?

Answer 1

I am tempted to say that Hades special talent was stealth. Prior to the Titanomancy he was given the Helm of Darkness, a helmet that rendered him invisible. Using this he snuck over to the Titan side the night before the day of battle and destroyed all of their battle weapons.

Also I am inclined to say that Hades, although stern, was also just. He did kidnap Persephone to be his wife but only after securing Zeus's permission -- something that neither Zeus nor Poseidon did in their romantic endeavors. And after the 'traumatic event' Hades did negotiate a more amenable marriage settlement between Ceres (Persephone's mother) and (as far as we know) was faithful to her there afterwards (unlike Zeus and Poseidon were to their mates). Also Hades negotiated with Hercules the use of Cerberus (Hades's dog) Hercules could defeat and capture Cerberus but had to not to harm the dog and later release him.

And Hades was smart. Sisyphus decieved both Thanos and Persepone but failed to do so to Hades.
