History TheUnintelligible / AnimeAndManga

* ''Manga/BlackClover'' has Gordon Agrippa. It's one of the reasons people find him creepy as he's always mumbling. It makes him look like he is always casting curses, though his poison magic can't actually do that.

* In ''Manga/DemonSlayerKimetsuNoYaiba'', within the setting, messenger crows assigned to hunters have been taught how to speak human language, Zenitsu’s messenger though is a sparrow that cannot speak normally, it tries to communicate by just repeating “chu, chu, chu” over and over again accompained by gestures, narrator text will sometimes translate to the audience what the bird is trying to say, but Zenitsu will remain lost on what Chuntaro is saying, Tanjiro on the other hand can understand the bird perfectly.

* Shouko from ''Anime/ASilentVoice'', due to her hearing impairment, has a very difficult time vocalizing and many characters do not understand what she is saying.

* The Legendary Tae Yamada, being a zombie, can only "speak" through groans, grunts, shrieks, and occasionally garbled imitations of others. And also chicken noises.

* ''Anime/DotHackSign'' has Macha, whose lips move and the other characters all react as though she's speaking normally... yet no sound can be heard. Apparently her words are displayed in the in-game text chat, which isn't displayed in the anime.

* Penelope/Chibimaru from ''Anime/{{Hamtaro}}'' can only say the words ookyoo or ookwee; her "older sister" Pashmina/Mafura is always on hand to explain what the youngest member of the group says.

* Keyop in ''Anime/BattleOfThePlanets''. He had lines in ''Anime/ScienceNinjaTeamGatchaman''. One fan rumour had it that he used too much profanity for the US networks. Probably not true though.

* ''Anime/DotHackSign'' has Macha, whose lips move and the other characters all react as though she's speaking normally... yet no sound can be heard.
** That's supposedly because she's using the text chat, which isn't displayed in the anime, for slightly obvious reasons.

* [[GentleGiant Sweden]] from ''Webcomic/AxisPowersHetalia'' often becomes this in FanWorks, after an [[AccentAdaptation attempt at localizing]] his TohokuRegionalAccent[[note]]Which, in Japanese, is perfectly understandable, if a bit unusual[[/note]] in [[{{Scanlation}} scanlations]] gave him truncated words and occasionally missing vowels. And after {{Flanderization}}, Sweden's often shown sp'k'ng l'k' th's.

* Sweden from ''Manga/AxisPowersHetalia'' speaks in a rather thick accent (Tohoku accent in the original Japanese, which translated into English is a sort of grunt speak), so sometimes readers have difficulty following his pattern of speech. Strangely when it shows him thinking, his thoughts are perfectly comprehensible.

* Lum's Mother from ''UruseiYatsura'', due to her lack of knowing Japanese, speaks in her native language, which humans can only interpret as gibberish (shown quite clearly in the manga, using various symbols in place of text). Naturally, Lum and other aliens don't have trouble understanding.

* Daikichi Komusubi from ''{{Eyeshield 21}}'' communicates mainly through grunts and short sentences. It's said he speaks in ''pawa-go'' ("Powerspeak"), which only strong men, like his "sensei" Kurita, can understand (though oddly enough, Mamori seems able to understand him as well).

* The Minicons in ''TransformersArmada'' speak in beeps. Towards the end of the series, they start actually talking. It's not clear how that works.

* Ryo-Ohki, the WeaselMascot in ''TenchiMuyo'' can only say "Miyaa," but is clearly an intelligent being capable of communicating complex ideas to the people around her. This is mainly due to the fact she is still very young. In ''TenchiMuyoGXP'' however, she is fully capable of speaking clearly. (Also TheVoiceless)

* Similarly, Mone-chan in ''{{Yumeria}}'' only says "Mone" or parts thereof. (It is unknown whether or not "Mone" is her real name; it was (unsurprisingly) the only thing she said when asked what her name was.)

* Keyop in BattleOfThePlanets. He had lines in ''Anime/ScienceNinjaTeamGatchaman''. One fan rumour had it that he used too much profanity for the US networks. Probably not true though.

* Likewise Mokona from ''MagicKnightRayearth'' can only say "Puu." While he may not seem to act like it and is accorded little respect, Mokona is arguably more intelligent than anyone else in the cast -- but the details are a spoiler of monumental proportions. (Also TheVoiceless)

* Targetmasters in ''TransformersHeadmasters'' also speak in random sounds.

* The MonsterOfTheWeek on ''Manga/SailorMoon'' usually suffered from Pokemon Speak syndrome.

* ''DotHackSign'' has Macha, whose lips move and the other characters all react as though she's speaking normally... yet no sound can be heard.

* Almost all Pokemon in ''Anime/{{Pokemon}}'', who can say only their names or parts thereof. With a little careful listening to regular cast members (such as Pikachu) in the original Japanese, though, it's possible to make out patterns. Ash (Satoshi) is "Pikapi", while Togepi, during the seasons that Misty (Kasumi) was with them, was "Pipipi." Likewise, Misty herself is "Pikachupi" and Team Rocket was "Pipikachu." Here's a [[http://bulbapedia.bulbagarden.net/wiki/Ash%27s_Pikachu#Pikachu.27s_language list]].

* Young I-Pin from ''KatekyoHitmanReborn''. She's supposed to be speaking Chinese, but no one else among the group can understand her. Aged-up I-Pin is somewhat easier to understand, having "taught herself" to speak the language (still not perfectly, but she's getting there).

* Sweden from ''AxisPowersHetalia'' speaks in a rather thick accent (Tohoku accent in the original Japanese, which translated into English is a sort of grunt speak), so sometimes readers have difficulty following his pattern of speech. Strangely when it shows him thinking, his thoughts are perfectly comprehensible.
