EDITOR'S OPINION

Len Carlson: While the Swamp-Thing show has gotten some criticism for how cheesey and goofy the show could be, Len was very good. He gave Swamp-Thing a very deep but gentle voice, I particularly like when Len got to monologue. You could to feel the weight he suffers and Len does a great job at making Swamp-Thing sympathetic and not go overboard with it. A stand out of the series.

Chilimbwe Washington: Chilimbwe was also good, giving a very similar deep but gentle voice. However, Chilimbwe sounded flat and even monotone on some lines, whether it was yelling or talking calmly. I do think he sounded fitting as Swamp-Thing but could have put a little more in the role.

Michael Dorn: While it wasn't hard to tell it was Michael, I like that Michael did something different with his voice and still fit Swamp-Thing very well. I think he could have been a little more energetic. I don't think he was stiff or anything but I just think he needed a bit more "oomf" in his delivery. Still, Dorn was a natural choice and it shows nicely.

JB Blanc: JB was an interesting choice but I think he was just decent. Nothing really bad but JB just sounded a little light when compared to the others. Though in JB's defense Swamp-Thing didn't appear much and even when he did his majority of lines were him under Poison Ivy's charm (then there is of course the "plant puns" that were pretty eye rolling). I can't say JB was bad but for what he needed to be, he fit nicely.

Mark Hamill: Mark is a natural choice for Swamp Thing but here he just does a normal voice with vocal effects added on. He's rather generic compared to the others.

Roger Cross: Roger has the right general idea but I felt he could have been better though Swamp-Thing does not get a whole lot of screen time.

Overall, I enjoyed Len Carlson the best with Michael Dorn second, Chilimbwe third, Roger Cross forth, JB fifth and Mark last.

Len Carlson's take on Swamp Thing is superb: he makes the character sympathetic, but also very mysterious and powerful at the same time.

Cross as Swamp Thing, though I thought the voice could've been better, IMO.

Len Carlson - I don't know why but there's something endearing about his performance, it eerily reminds me of Lou Ferringo's performance as the Hulk; it's this cryptic yet considerate tone that makes him sound scary yet also empathetic and relatable, almost like an animal you observe in the wild, a creature just living in it's environment familiar with all they know around them. (though I may be acting pretentious with how good I think it is ^^;)

But I'd have to say Michael Dobson is my current favorite voice for the character. It's not as cryptic as Len's but it's still just as endearing, and has a bit more energy, as well as a more intellectual charisma.

JB Blanc was fun to listen to, there's just something about his performance that reminds me somewhat of Jim Cummings. Sure he could have been deeper, but for a more goofy take on the character it was good enough, even making the puns not clumsy.

Roger Cross has perhaps the most the most intimidating voice for the character, not surprising since he did play Doomsday at some point; it pretty much harkens back to Len Carlson's performance in how the character is less of a monster and more of a force of nature, a misunderstood creature if you will who just wants to be left alone, tending to his own environment.

Then there is Mark Hamill... truth be told I actually liked Mark's rendition of Swamp Thing, nothing obviously monstrous about it but that's practically the point, because he's not a monster; and even then this is what made this take so interesting, a more laid back, but still hands on type of a superhero character who can actually make it fun to watch. Is it the best voice, probably not, but it's still has charm to it.

Overall, I'd say Len and Michael are tied for 1st place, with Roger in 2nd, Mark in third and Mr. Blanc 4th (at least by default)

BONUS: Okay, let me get the typecasts out of the first, then we can get to some slightly obscure picks--

Obvious Choices: Kevin Michael Richardson, Steve Blum, Fred Tatasciore, Dee Bradley Baker, Clancy Brown, Richard Epcar, Greg Berger, Paul St. Peter, John Dimaggio, Gary Anthony Williams, Nolan North, Travis Willingham, Scott McNeil, Michael Dobson, Neil Kaplan, and Ron Perlman

Less Obvious: Paul Eiding, Greg Baldwin, JG Helzter, Mark Rolston, Jonathan Adams, Jim Meskiman, Jim Cummings, David Kaye, Trevor DeVall, Eric Bauza, Chris Jai Alex, Matt Mercer, Troy Baker, Brian Bloom, Crispen Freeman and Phil LaMarr

I like Len's very laidback sound for the character, plus that great raspy voice for the character. He sounds both powerful yet intelligent at the same time, plus it's a really nice showcase of range for him.

Chilimbwe is okay, but I think his delivery comes off as a little flat, and I think he sounds too raspy to the point of making him almost sound frog like.

JB is suprisingly disappointing with this role. Considring his range I feel he could've a great Swamp Thing, but he's for some reason underplaying I feel here. The voice is too light I think, and his delivery sometimes comes off as kind of stilted.

Dorn I think finds the right balance between both intellectual and powerful. His delivery is really well done, I like his confident tone to the voice, and I like that he makes it a bit light, but at the same time sound like a big and powerful creature.

Mark is also pretty disappointing I feel. His raspiness is fine, but I think he's a bit too light and he doesn't really add anything all that memorable to the performance. I do agree that something like his Solomon Grundy would've worked much better, or even if they just pitched the voice he was using it probably would've worked more.

Cross sounds incredibly intimidating and it's just really cool to listen to, though I feel the one drawback is he doesn't have a huge amount of material and his delivery is really flat at several points.

1. Michael Dorn
2. Len Carlson
3. Roger Cross
4. Chilimbwe Washington
5. Mark Hamill
6. JB Blanc

I'd say for a future VA. I'd like Blanc to try again with better material, but I'd say for a new person, Fred Tatasciore.

Roger Cross has a cool voice, but he doesn't seem all that interesting. It's likely just how Swamp Thing is portrayed in the film, I dunno as I haven't seen it.

I do think that the character should sound deep, though he might be a little too deep.

Len Carlson. I know a lot of the DC & Marvel shows in the earlier days have dated voice acting, but Len is brilliant as Swamp Thing. The deep voice adds weight to the performance & he also did a great job making him sound sympathetic.

Chilimbwe Washington is also very good. A standout from DC Universe Online. He even did a good job with his monsterous side.

JB Blanc. He's pretty decent. He needed more material, that way he could have shown his full potential. He does have some energy in his performance so that does help.

Michael Dorn has the better voice when compared to JB, but he has the opposite problem that JB Blanc did. He's lacking the energy.

Mark Hamill, unfortunately is the worst one here. He could have done a variation of his Solomon Grundy voice, but it's his regular voice with effects added to it.

My vote goes to Len.

My Top 5 Voices for Swamp Thing

5. Chilimbwe Washington
4. Mark Hamill
3. JB Blanc
2. Len Carlson
1. Michael Dorn

Future VA Suggestions:

DAN GREEN! Seriously a destorted version of his Entei would fit Swamp Thing perfectly, that and I really want to hear Dan Green voice a DC Character.

Bruce Boxleitner would also be good for a perfomance similar to Len Carlson's.

I also recommend Colin Murdock, Ron Halder, Robert Davi and TC Carlson.

VC thoughts update

Len Carlson was just great as Swamp Thing. His murky sounding voice combined with his sympathetic delivery just makes him quite memorable. Plus, he does sound pretty intellectual.

Mark Hamill is also quite good in the role. He does sound quite likeable and like Len, he does sound quite intelligent at times.

Michael Dorn sounds pretty good too, but he's a little bit too exaggerated at times.

J.B. Blanc is also good, but he lacks the intelligence needed for the character.

Chilimbwe Washington has the right idea in terms of voice, but is delivery is just so flat that I can't rank him higher.

Hamill's Grundy or his Skips voice from Regular Show mixed in with those vocal effects, would have worked much better. Here it sounds too bland.

You know, seeing this makes me wish more of Swamp Thing's cast would appear in games or more recent animation. I mean, John Constantine appears in DC Universe Online, but since the 1990s cartoon and the live-action seires, it's just been either Swamp Thing or Constatine.*

* I'm talking actual appearances, I'm aware that Jason Woodrue/Floronic Man is mentioned in Batman: Arkham Asylum.

JB Blanc can go deeper and maybe should've here, though considering the LEGO games are quite a bit lighter, I can excuse it and to be fair, he is decent in the role.

Blanc is a nice choice for Swamp Thing, however he's saddled with silly dialogue in a comedic version. He's not bad, but doesn't get to really show off much and that voice doesn't say "Swamp Thing" to me. I'd like to hear him get another crack at the guy with something not so comical.

This is kind of hard to be honest. But I think I have to give this to Carlson, because he does seem a little more invested in the role, while Washington does sound like he is more so reading his lines at points.
