The name "Dipthong Johnnae" came to me one day out of the blue, when I wasn't even playing the game. I had probably heard the word dipthong recently, and I wondered how that would work in a name. Pretty darn good, IMO. :)
Too bad the game would not allow "Dipthong JohnnŠ".
At that time, VEATs could only be created villain-side. Since (an unwritten) part of Johnnae's backstory was that he had escaped from Arachnos, it made sense to switch alignment when that became possible later in his career. It sure was hard to get his extra arms serviced in Paragon City, though!
The neatest thing about playing a crab spider is you were essentially a blaster with mez protection and shielding. You didn't do as much damage as quickly as an actual blaster, but the trade off was well worth it. Add the two sets of pets you get later in your career, and you were very powerful indeed. All VEATs have shared defenses, so if there was more than one VEAT on a team (and/or some other shielding archetype), everyone became well protected.
