One anime that total be undo for me is death note.

The death of Maes Hughes, FMA.
Other than that, I do not believe I would change anything. Maybe not even the tragic death of Hughes, because it happened. And undoing things that happened isn't my wish (damn you Fate Stay Night for teaching me this ideal!!)

Titan attacks.
Wolf Rain's ending
Inuyasha's choppy ending

Not an anime, but a manga (a manhwa at that). Beware, spoilers for Hot Blooded Woman below!

I would undo Aram dying and Ha Ji waking up from her comatose state with no memories of her body switching experience with Aram. It happens around volume 11 and I feel that after this the series took a turn for the worse: the guys are acting extremely creepy and downright illegal, all the characters become hypocrites and the memory loss plot device is so overdone that it's painful to read about.

It became so different from the original plot (which wasn't original but was at least entertaining) that I'm not sure I want to finish this series anymore. All the characters are assholes, I'm not rooting for anyone and don't care what happens to them anymore because they've suffered a complete personality change :/

I have no problem with characters dying, btw, and from reading the comments I'd have to disagree with L (Death Note) and Wolfwood (Trigun)'s deaths; they made perfect sense in advancing the story. Light and L had to have a confrontation or the cat and mouse game would've become too drawn out otherwise, and Wolfwood's death served as an even bigger motivation for Vash to go after Legato and Knives.

/spoiler party

The ending of Chrono Crusade >_>;

If given the chance, I'd undo Kamina's tragic death in ep. 8 of Gurren Lagann, but I would have to first save Simon from what caused him to suffer distraction during the day of that tragic moment so that Team Dai-Guren could win the day without any loss of members, and Kamina and Yoko could have a future together.

@Darkarax:

True. Dont know why they keep continuing it

BRING BACK MAES HUGHES!!!
he was too awesome to kill off...

WARNING PPLZ:
UNCENSORED SPOILERS

Ulquiorra's death on Bleach. It was so sad. And L's death on Death Note in which I cried. One of two times for a fictional character.

@Thiefspawn:

And it just kept getting worse and worse after that.

Hmm...I would definitely keep Yamato alive in the anime version of Devil Survivor 2. I don't see why he had to die in the first place... then again, the anime doesn't follow the game all the way through :/

I would say "Another" since the cursed class should've just told Kouichi. I mean seriously, if he didn't know, why wouldn't he talk to Mei? Wtf...but I guess if they had told him first off, the series would've lost the first few deaths...

There are lots of event but the story wont remain the same and characters and their bond will change as well.

@Darkarax:

True. The series with Misty were great but after that.. Epic fail

Hughes death in FMA. Although in Brotherhood if it hadn't happened I'm not sure if Roy would have had enough rage to blast those homunculus to oblivion like he did.

Kaworu without a head ;____________;

Higurashi no naku koro ni: Keiichi giving that friendship speech to Rena at the end of the show. It annoyed me so much I couldn't stop laughing. Say what u want but a scene like that after all those murders? No. Just... No.

@Hisaishi:

That is exactly what I think. I think it's ridiculous how easy all the antagonists died, yet how the protagonists could recovor from worse things in what probably would have been under an hour. It didn't have to be one of the main characters, but SOMEBODY should have died, like Sid or something, to show exactly how serious the battle really is.

I would redo the death of L. I cried for a week, then I saw this posty-thingy that said: "L didn't die he just went to Bleach in the from of Ulquiorra". I loved Ulquiorra as well! and then what he died too!! Urg but I can't complain, their deaths only made me love them more! I would also like Jiraiya to come back to Naruto, I really liked the old Hentai!!

Like the others said, it would have to be the death of L in Death Note. The rivalry between L and Light, as well as their short-lived team-up, was what really made Death Note amazing to watch. After that event, it just felt a bit depressing that you just want to know how it would end.

Another would be Athrun breaking up with Cagalli in Gundam Seed Destiny. I'm not really into love teams nor am I a huge fan of Gundam Seed, but I thought the two were quite a couple. Seeing Athrun go for a lesser known character just felt out of place, especially since the show (at least in my case) didn't let the character develop so that we could really see her as a better match for Athrun.

And lastly, the ending to Canvas 2. An older male cousin (who also works as a teacher) and his younger female cousin (who appears to be a student in the former's school). Seeing the final scene of the show felt so wrong to me that I somehow curse the fact that my brother even thought about bringing a DVD of that show. "It will be fun," he said. "The animation is good," he said. Well, big mistake.

I would redo Light killing Ray Pembre in Death Note. The biggest mistake that led to his ultimate defeat

Everyone please put a spoiler warning about the series first if you don't want to add the spoiler bars.

Trisha Elric dying in FMA.....Wahahahaha, there wouldn't be a series if that happened...but daaaaamnnn it's depressing.

Guh.. at the end of the Pet Girl of Sakurasou,when Sorata and Shiina were about to kiss, the cat totally trolled them... i would have loved to take out that cat and actually see them kiss. The end was beautiful, but that would have made it more perfect.

@Keba Si Rota:

Exactly, there was no point to killing her off. I was fine when they killed Kamina off because that actually served a purpose. But there was simply no point to killing off Nia except to ruin the series.

Sorry to post so many times in a row, but here's one opinion of my own. I bet I have more things I want to say about different series, but I'll give you just this for now.

Click this. It's a lousy ecard that I made years ago, but I didn't want to retype the whole thing.

Heck, I would have rewritten a lot of Sasuke's character. I understand that the events of his past would shape who he is when the series starts, but over time I'd have him warm up to Naruto as a friend and THEN they would have a falling-out. Naruto being bent on saving Sasuke would make more sense if they had actually had been friends, even if only briefly.

Speaking of Naruto, I would explain a lot more about why the characters look the way they do. Yes, Kisame looks like a shark-man. Why? It's not enough to say he's from the Hidden Mist where they're all about Water Style stuff. I want to know why his skin is blue. If anyone has a theory about this, I'd be happy to hear it.

That gives me an idea. Adam, for a future topic, maybe you could make it about head-cannon. You know, what fans make up about characters to fill in the blanks.

@Archmage225:

I gotta agree. I wasn't as invested in Death Note after that. Still a cool anime, though. But I would have made the ending more like the manga.

@Darkarax:

Heck yes. When Nia died in Gurren Lagann, I was like, "this is the end?" Another thing that bothered me was that Simon seemed OK with it. Or maybe I should say instantly at peace. I didn't really buy it, especially after the whole thing with Kamina. Also, if he knew she was going to die, what was the point of him rescuing her anyway? To me, if the anime had an altered ending, that would have made it just about perfect. There were other things that they could have played up too, such as Viral's immortality.

(By the way, I downloaded one of your Gurren Lagann wallpapers. I suggest you go back and edit some of your comments to add spoiler tags there as well.)

I agree with what you said about the Pokemon anime, too. Though I stopped watching it long ago.

@:

Hear, hear.

Ace????

Or the fact that reiner from attack on titan IS THE ARMOURED TITAN LIKE WHAT THE HECK

I wanna change THAT part at episode 17 of black butler season 1. *inner rage* STUPID NUN.........

And also I wanna change how ceil turns into a demon at the end of season 2

Hands down, I would undo the death of L in Death Note I thought the series went drastically downhill after that.

One other thing I'd like to change (and this'll be my last word on the subject) is Misty leaving the Pokemon anime after the end of the Johto saga. Not to mention the rest of the series after that point.

I'd also like to change the end of Yu-Gi-Oh! 5D's and have Yusei and Aki actually kiss and get together at the end of the series.

This is something of a spoiler, but I'd change the ending of Gurren Lagann and prevent Nia's death during the wedding. There was absolutely no point to it and is just ruined the whole series for me.

Also, shame on Aku no Hana for not going twenty-six episodes in the first season. Make Part 2 already so I can reason with people as to why this show is good without getting weird looks.

JUST A FRIENDLY REMINDER THAT WE HAVE A SPOILER TEXT OPTION FOR A REASON! USE IT SO WE ALL GET ALONG NICELY! THIS HAS BEEN A THEOTAKU.COM PUBLIC SERVICE ANNOUNCEMENT!

That being said, I would undo the fact that in Soul Eater, everyone on the good side survives. . Just because the anime in based on a manga doesn't mean you should follow the manga. There were times when Crona, Death the Kid, BLACK★STAR, and Lord Death could have died, but they didn't. Considering the situation and the fact that nearly every villain is killed, the heroes get off scott free in a high stakes match. In the manga, it makes sense because they were necessary for the cause later on, but those arcs aren't even covered in the anime. It's one of the rarer times when I wished death upon a character.

The (second) season finale of Pokemon Black and White. I HATE how it ended! Plus N didn't get nearly enough screen time.

nabari no ou when yoite die

I would've made the end of "Samurai Champloo" a lot more action-packed.
