You're right the enemy of evolution is no evolution which is either what the Anti Spirals were doing or death. Death is what the Anti Spirals was referring to when talking about the Spiral Nemesis but as I said they themselves at Spiral Nemesis too since they are trying to stop evolution. BTW IMO the end of the universe through death is evolution (I'll explain that when I talk about Simon's emotions below).

You win, I check the official japanese site and they refer to him as human. All I can say is I blame Genome for always isolating himself from humans speices when he talks. Lofty mofo.

The problem is when you think "if my girlfriend was killed what would I do?" When it's actually what would Simon do. And Simon has demostrated that he never takes revenge for anyone's death or blames anyone (even the enemy for anyone's death). All he says is that they died fighting for what he believes in (since he is the leader) and he hopes they didn't die in vain. When Simon snaps out of his depression of the death of Kamina he realises that part of being a Spiral being is knowing that the old must die to let the new move forward. Hence, what he said in the end, "Dead people are dead people. If we revive them unwillingly, they'll just get in the way of our followers (crappiest translation I ever heard but general means things die so that new things can grow, hopefully Order finally translates the whole series so we know what he really said)." He accepted that Nia will die sometime during the cause of the rescue probably which why he tells her to hang on to herself (her original personality) so when he does manage to rescue her, he rescues the real her (not the Anti Spiral personality which would she 'died').

"I kill your best friend/big brother when you are a little kid, do you expect the little kid to go berserk and kill ppl? If I kill your girlfriend in your adult years in cold blood (because i like it) will you just sit down quietly and cry especially when you know I'm still alive laughing at you? I don't think you can compare Nia and Kamina to Simon's reaction." When Simon is a kid he has this super powerful mech and being a kid you tend to imagine yourself immortal (nothing can touch you). Secondly, the Anti Spirals didn't kill Nia, they took her captive. And are trying to control her personality. They were not laughing at him and they did state the reason why took her (to be the messenger of mankind's destruction and to analysis the data they collected). Simon was also given the facts by them for the reason of the war between them. They didn't say, "Hey, we took you GF to we can f*** with you man, hahahaha." They said, "We took Nia because she was a spy we planted a long time ago as part of a monitoring system to make sure you humans don't super evolve and destroy the universe which you are directly at fault for!"

"Hey i don't think Simon walking in Kamina's shadow makes him reckless and arrogant." Watch the episodes after Kamina's death. He was reckless and arrogant because he was depressed and thought he should be the only one that should fight. If he was to follow Kamina's style of solo combat with the power of Gurren Lagann after a while he will not value teamwork because the others will be below him in terms of power and skill. Give it more time he won't value his team anymore, more time he won't value anyone weaker than him. Jump 7-10 years to the future and anyone below his power is scum to be destroyed or enslaved.

Spiral Nemesis can come from the other Spiral races that Rossiu is having a 'peace' conference but from the dialog of the other sub-characters they are not expecting it to go well and are prepared to fight.

"There will be 2 new lagann shows apparently. The movie, which will "betray everyone's expectations in a good way"and a OVA, which will fulfill the fans of the TV series...probably a "what happened after the war" episode." I think the movie maybe a reinmagining of the series. And the OVA is the conflict of the Spiral Races for dominance of the galaxy. Whatever it is, I hope it is good!!
Yes, I and I am sure wolfx watched the anime for enjoyment value. Then like any good book we both take a good hard look at its universe and try to hear what the writers, animators and producers are trying to us. Like, any good book, every story has many layers to it. And if you happen to like the top layer we can't fault you. And no, Tengen Toppa Gurren Lagann is not for children.
Or yeah Eva... the only anime that everyone thought there was a meaning to but really in the end it was the work of a drug induced and depressed writer. Please, if you think Eva has anything meaningful in it, it may be in the 1st half of the series. After that, it's all pink hippos and Lucy and the Diamonds in the sky.
