Time to give this place a little nudge.
Though a loyal minion of His Tentacle-Ness, Otto Octavius, I have to admit that I've recently developed a definite liking for Electro. It started with Castro's Sinister Six novels; Castro does all the characters justice, but he pays special attention to Max.
I dug up and read "Light the Night" which was quite excellent; that and the arc in which he gets powered-up are my favorites so far.
Some Electro fan-art I dug up on deviantArt:

...Man, I don't care what anybody says. I /like/ that adorkable costume, mask and all.
