If Alex Mercer is Zeus, what about him?

Venom....oh wait....

infamous or hero

whether good or evil, inFamous

well in the game he was known as electric man

Going by the "thunder god" theme, maybe Jupiter or Tinia (Roman and Etruscan variants of Zeus, respectively).

Raiden?

Evil Cole: Blackout/EMP Good Cole: Electrolyte/The Ohm or for good and bad I was thinking The Ion because ions can be positively or negatively charged aha

I was thinking Lightningfinger 

whats wrong with infamous?

Well, everyone call's him 'The Electric Man' which sounds pretty good.  
But if we're going for something with more of a superhero feel to it, I'd say his code name should be 'Voltage' 

they also call him the demon of new marias.

White Lightning. Like Black Lightning, except white. -____-

@ZacCooper: Nice! I like those ideas

@BlackArmor: Dude epic with the spoiler alert then the name, that was BAMF

Im okay with Ion, Infamous, Voltage, and if he's evil, The Beast

icebolt(good)

firebolt(evil)

@ZacCooper: i like most of these

Recharge 

Maybe Thor or Raijin would work.

The Electric Vibrator

What about electric vampire? You know, aside from that spinoff game, he sucks out blood electricity

And hey, I'm new to the forums, this place looks great

I'm gonna go with Volt. Goes well with "Amp", his Tool of Destruction. Hehe, Ratchet and Clank reference. Anyhoo, the unit of electricity flies well, and Watt just doesn't have the zing it needs.
