Onomatopoeia for a long, intense scream - "AAAAA!!"


How could you describe a very long, very intense scream - one that expresses
extreme anger or pain? So far I've only been able to find examples of short
gasps, or screams with happier connotations.

In particular I'm looking for the equivalent of reading the word [_"
AAAAAAAAAAAAA!!"_ in a comic
strip](https://pbs.twimg.com/media/Ed9osQUWsAQWYK7.jpg), which can be
stretched out as long as you like by adding more A's. Does Japanese have a
version that can also be infinitely-repeated like that?




One option that’s rather difficult to type in normal font is あ゙ (あ with ゛
(dakuten)). Although not an official letter, it’s been used in manga to
express approximately the effect you are looking for.
