I have to warn you…I am now about to geek out for a few, so bear with me.
Okay, I’ll start with a confession…in the never-ending turf wars between Marvel and DC fans, I come down squarely on the side of DC every time, which is why I’ve been looking forward to SOE’s DC Universe Online.
I have played more than my share of City of Heroes, and am looking forward to Cryptic’s Champions Online, but this is something different…and that could be good or bad. With both CoH and Champions, there isn’t really an established world that they’re trying to adapt.
With DCUO, it could be argued that the world IS the game.
And that means that writing, voice acting and terrain design will take on a different level of importance, because most folks have a mental image of what Superman or Batman look like, act like and sound like, and if SOE misses that mark…it’ll be trouble.
Sony’s job with DCUO is something akin to turning a popular novel into a movie; there’s not a lot of room for error; usually, a novel-to-movie translation is either really good or it stinks. There’s not a lot of middle ground. And that’s what’s staring SOE in the face on this project. (Although if this screen shot of Green Lantern from the E3 demo is any indication, they should be able to pull the visuals off with no problem.)
The developers spent their E3 time promoting the fact that this game is not going to be a typical MMO; they want you to feel that you’re stepping into the DC Universe. Great…that’s what I want. But while we get promo after promo featuring DC’s “big guns” (Superman, Batman, Wonder Woman, Flash, etc.), to me what will make or break this game will be the little things…the characters that most folks would say “Who the heck is THAT?!?”
With that being said, here’s my list of the Top Ten Characters that should be in DC Universe Online, even if only as a cameo.

10. Wildfire - Not saying that I’m a huge fan of this guy, but my son’s name is Drake. No, really. Wildfire is a member of the Legion of Super-Heroes, and his body is composed of “anti-energy”, which is what I usually have before noon each workday. The only thing that gives him human form is his containment suit; if it’s punctured/destroyed, his energy floats around griping to itself. Powers: flight, anti-energy blasts, and at one point the powers of the entire Legion.
9. Booster Gold - I’ve always had a soft-spot for this guy for some reason. He has the power to fly (thanks to a Legion flight-ring), and various other powers including a force shield, force blasts, and a knowledge of the future, since that’s where he came from. He also has the innate ability to be a complete screw-up…at least until lately. However, as much as I’d like to see him in the game, it just wouldn’t be the same if Blue Beetle wasn’t there to join him in a rousing “Bwa-haa-haa!” And since hints have been given that continuity between the comics and MMO universes will tie together somewhat, that means no “Blue & Gold”. Sigh.

8. The Spectre - Oh, c’mon…I would completely LOVE to watch the “Nerf the Spectre!!11!!” flamewars on the official forums after launch. The Spectre is a longtime staple of the mystical side of the DC Universe, who fills the role of “The Vengence of God”. He’s nearly omnipotent, and has a habit of turning up when you don’t want to see him, and being off screaming at a comet in some higher plane when you really DO want to see him. (Sorry…Crisis on Infinite Earths flashback there) I have no idea how you would balance “omnipotent,” but WoW seems to have done a good job with warlocks in that situation.
7. Blue Devil - Dan Cassidy deserves his time in the game world, especially if SOE plans on delving into the mystical side of the DC Universe. Dan started out as a Hollywood stuntman that designed his own devil suit for a movie he was working on. An actual demon was on the island where they were doing location shooting however, and fused Cassidy into his suit, which boosts his strength and speed. It has recently been revealed that he’s an actual demon, which leads me to believe that DC and SOE wouldn’t touch Danny boy with a ten-foot trident for the MMO.
6. Metamorpho - Okay, devs…let’s see just how good you really are. (insert evil laugh here) Rex Mason was an “Indiana Jones” type before Indiana Jones existed, working for his girlfriend’s father. However, when his potential father-in-law left him for dead in an Egyptian pyramid, the mystical Orb of Ra changed him. Now, Rex is a cross between Plastic Man and your high school chemistry teacher, able to change into any of the elements that are contained inside the human body, and alter his shape as well. That could be a hard power to pull off in a game.
5. Major Disaster - The list of cool things they could do with this guy is practically endless…as long as they’re going to have weather effects in the game. A former villain that reformed (and eventually joined the Justice League), MD has the ability to…well, to create natural disasters, any natural disasters, at will. Since reforming, he’s put out forest fires by causing a flood, he’s attacked a monster by causing a direct meteor strike on it, he’s…you get the idea. He has a fairly underrated power, and it could be used to cool effect in DCUO…especially if they use the old “evil” Disaster…now this guy would be a raid boss!
4. Firestorm - Imagine a teammate freezing a foe in a block of ice, and then Firestorm molecularly restructuring it into titanium steel before you throw it, and you’ll see what this guy can do. Also, Firestorm is actually composed of two humans fused together, which could make for an interesting in-game experience…what if Jason was looking for someone to fuse with, and your character walked up just at that point? An interesting, non-typical mission, to say the least.
3. Dr. Fate - C’mon…mystical power…good color scheme…nice helmet. What’s not to like? I don’t even care if it’s Kent Nelson, that Jared idiot or Hector Hall taking orders from Nabu under the helmet, it will not be the DC Universe if this guy doesn’t make an appearance. (And yes, I know Jared didn’t wear the helmet as “Fate”…work with me here.)

2. Plastic Man - Again, I say - devs? How good are you? A former crook,”Eel” O’Brien was doused by a bizarre chemical, right in the ol’ fresh bullet wound, which gave him the ability to…well, bend, stretch and shape himself in any way he wants. It was also learned during his time with the Justice League that he may, in fact, be immortal, and Batman holds the opinion that Plas is one of the most powerful heroes in the DCU. No, really.
And the one I absolutely would have to see in the virtual analogue of the DC Universe:

1. Ambush Bug. Whoop, I say…whoop! Yes, I’m serious. And apparently, he may very well actually be in the game, since Jim Lee referred to having to find reference art for him while working on DCUO during an interview with Massively. And I quote, “There are definitely a lot of characters where you’re concepting it out for the first time and you go, “You know, I don’t really have something to draw on.” No source of inspiration. Ambush Bug, right? I dunno what Ambush Bug should look like.” So if he’s looking at Bug, my other top nine don’t look too stupid, now do they?)
Okay…I’m done. Who’d I miss?
