Used at the climax of episode 3 by Amy Rose, Sonic's self-appointed "girlfriend".

Though the series engages in more and more towards the end, the biggest of Big Noes in Neon Genesis Evangelion are one by Asuka at the end of herMind Rape, one by Shinji after realizing his Mecha has been used by his father to crush the Entry Plug loaded with his unconscious best friend, and one by Maya Ibuki (who spends most of End of Evangelion freaking out) after Giant Naked Rei's hand passes right through her entire body. Some of these were dubbed into English as inarticulate yells, probably to avoid being straight-up Narm.
Since the Japanese word usually used for the Big No, "iya," sounds like a scream anyway, it only makes sense to translate these as such.
Used in Nadia The Secret of Blue Water by the title character, twice in the final episode first when Emperor Neo sacrifices his life to free her from Gargoyle's control, and, even more heartbreakingly, when Gargoyle kills Jean by making him fall to the floor. (Nadia eventually revives him with the Blue Water.)
In Digimon Adventure, Hikari does one when Wizardmon dies, leading to the activation of her crest. It was strangely cut from the dub. Equally as strange, the clip was shown in a brief flashback in a later episode, except during a voiceover narration, so her voice was not heard.
Also used in the episode "Ogremon's Honor" by Mimi when Leomon dies
Ill Girl Hayate has a huge, primal one near the end of the second season. Considering how it punctuates a particularly nasty Break the Cutie moment, the overall effect is quite chilling.
In the fourth Megami sound stage, Shamal gives one in a more light-hearted moment when Agito inadvertently shows Hayate a cake from Nanoha's parents' cafe that was supposed to be a surprise (as part of celebrating the tenth anniversary of Hayate recovering) due to being unable to read the kanji on the box.

In a mid-series episode of Mobile Suit Gundam Wing, Duo gives one out when Trowa destroys his Gundamnote As part of an If You're So Evil, Eat This Kitten situation. It's even bigger in the US dub; voice actor Scott McNeil has said in order to achieve this, he thought about the time his wife ran over his motorcycle with the family minivan. It's actually so famous that he's often asked to re-enact it at conventions.
In Robotech The Shadow Chronicles there are two moments - first when Commander Tailor dies and then when Alex Romero sacrifices himself. This one is especially strong.
Simon from Tengen Toppa Gurren Lagann performs a variation on this trope, instead shouting "ANIKI!!!" when he believes Kamina has been killed by Thymilph. Kamina, however, stays alive just long enough to make a Heroic Sacrifice in the form of the Giga Drill Breaker.
The king (or rather, queen) of this trope is - surprise, surprise - Kinon. When Rossiu is about to shoot himself in the head, Kinon screams out a teary DAAMEEEEEEEEEEE!!! which stops him dead in his tracks - just in time to receive a Get a Hold of Yourself, Man! punch from Simon.
The second Greed gets one of these after the revived and amnesiac Greed unknowingly kills the last living member of the former Greed's Quirky Miniboss Squad. Ling, who's body the current Greed is inhabiting, asks What The Hell Anti-Villain, causing the old Greed's memories to resurface, with the new one letting out a screen-filling, gut-wrenching, Big No.

Even earlier, in the dub only (he screams "Goku" in the original), Krillin uses one when it becomes clear that Goku is going to sacrifice himself to take Cell away.
In the dub, Trunks seemed to have mastered the Narm of the Big No, with lines like "If they let that android free, it will be the end of all of us! NOOOOOOOOOOOOOO!" (Lampshaded in this fanvid: http://www.youtube.com/watch?v=_HOAETv_nVo) and not too long after "FATHER! hurgh, NOOOOOO! FATH-ER!"
But Trunks also has a decidedly non-narmy Big No in the dub of his OVA when he finds Future Gohan dead. In the original Japanese, it's a simple Skyward Scream.
Earlier than the other times, Goku lets out one of the biggest Big Nos ever: after defeating Frieza on a crumbling Namek, Goku tries to escape on Frieza's ship, but unfortunately, the ship was damaged and plummets into a fissure to dissolve in lava, leaving our hero with no way to escape.
Goku uses instant transmission to do a point blank kamehameha on Cell here.

Chitose utters these quite often when having to deal with his self-proclaimed mothers on Happy Lesson, but the entire Biology class gets one when the lesson of the day is: "Dissection - Live chicks".

In the first InuYasha movie (both the English and Japanese versions) Kagome lets out a rather chilling one after being forced to shoot Inuyasha by the Big Bad Complete with lack of BGM and echoes. It is used rather effectively though.
In History's Strongest Disciple Kenichi, during a financial crisis, Miu has the masters of Ryouzanpaku give lessons to small children. Kenichi is amused to see the straight-faced (but cruel) Akisame being run ragged by the hyperactive kiddies, but enacts this trope when he later sees what kind of effect his teachings have.
At the end of the first ep of Nyan Koi!, Junpei lets out one in its full Engrish glory.

Gankutsuou: Victoria Danglars does this in the 8th episode before fainting.

Happens in a couple of Hinako Takanaga's works:
In The Tyrant Falls in Love, the homophobic Hot Scientist Souichi does this whenever his lab assistant Morinaga comes onto him. Matters are confused because he doesn't want to face up to his potential homosexuality and so pretends to resist Morinaga to satisfy his own guilt even when he secretly wants to have sex - the Big "NO!" comes out when he really doesn't want it and needs to make that clear.
In Little Butterfly Kojima pushes his boyfriend Nakahara off with this whenever a makeout session gets too intense and it looks like sex might happen. Needless to say, this happens quite a lot.
