Now that the series has ended (I watched the end last week and now I'm watching Bomberman Jetters) I'd like to comment it. Now, I'll review all seven Cobras and one Joe for each, a la "vs. pack". (SPOILER WARNING)
The dead guys:

: His body appearance was very over-the-top. It was a desperate "Hey, look! We're violent! Will you watch us?". There shouldn't even be so many Blood! He was killed in Springfield! Also, his death was just that, a death. His treachery is neither well explained nor contributes anything to the rest of the series/movie.
Bazooka: He was a well-done corpse, up to the costume, so everyone knows the dead guy was Bazooka and not any greenshirt. His dead body even contained a message that contributed to the story.
The leaders:

: He was a jerk. The world is in danger and he uses that moment to make

choose between :snakeeyes: and himself. However, he was very clever in the last battle (that last idea was a little reminiscent to what Midnighter did in Authority #4). Oh, and other bad point: He killed a

who was already defeated. One thing is to kill in battle, but, if the

is on the floor, it's handcuffs time. Don't think bad, I liked

in the original TV series.

: Cool! He is really a great villain. I found a little over-the-top when he said "crap". The main villain should be more regal elegant (like

and

), but all the rest of the time he was great. I mean, he blew Moscow! That's a villain!
The ninjas:
:snakeeyes: : Absolutely perfect, I can't say anything else (he neither).

: I didn't like him. For me,

is the noble villain among

, but this version was very evil. I also like seeing

,

and others being noble villains, but I don't find it something that defines them, except for... you guessed,

, so this guy was, for me, the most despicable Resolute character. So good :snakeeyes: killed him.
The co-leaders:
Flint: While Duke was in Omsk, Flint acted as leader, and was a lot better than

(that's because Flint trusts Lady Jaye will never leave him for Cap Grid-Iron, while

is unsure if

prefers a cool ninja master or a jerk, Bwa-ha-ha)

and

: (I have to review them together) Very well done. The had an evil but aristocratic attitude, and they flirting was also very well. I like

more with the noble streak he had in the Hamaverse, but I don't find it vital, so I liked the character. Well, both characters. And so good putting them together. I also liked they being incarcerated rather than killed (an "all baddies die" approach would have seem a bit unrealistic)
Counter-Intelligence vs. disguises:

: At the beginning, she was cool, and I even liked her deciding to stay "with the team" rather than with

, but that went downhill when, in Omsk, she said she had chosen

. Why, Shanna, why?

: His scene in Omsk was very short, I didn't like the idea of a main character having a "hi-then-die" appearance. I think Ellis only used him there because he had already used him as the Hard Master's killer. However, he could have made Zartan just appear in the HM's death scene, just like

didn't appear after shooting

's message.
Main comic characters, background TV characters:

: His shooting abilities are awesome! sadly, he just appeared a little, so we couldn't see him in action. However, that has a good side: in case of a sequel,

still has him alive, just like

and

: His role was a little short, but clever; he saved the scientists while

and

distracted

and

. Despite the small role, it's good to see him animated again.
Sorry, I reviewed just 6 Joes, but I had to review

and

together. Please, Baron, mercy!
