Although a pop/rock performer of substantial fame and talent with an international following, she is probably best known in the United States for the hundred or more roles she's played in various anime and video games; reading her resume is like reading a history of the best in Japanese animation.
Megumi Hayashibara was notably part of the wave of seiyuu, along with Hekiru Shiina and Mariko Kōda, that became popular in the 90s due to the large amounts of money provided by recording companies and the more multi-media approach to stardom developed at that time.
Just to name a few of the characters she's voiced, she has been:
Any
one of these roles would be a career-making milestone for a voice actress, but Hayashibara has had the talent and skill to win that kind of part again and again. She is such a major figure in anime that the character of Megumi Reinard in
Martian Successor Nadesico was actually based on her, partly as parody and partly as tribute. She is arguably one of the few seiyuu who isn't
set in a role.
When she has a part in an anime, she frequently performs its
theme song; she is also in demand to record themes for other animes as well, such as "Treat or Goblins" from
Abenobashi Mahou Shoutengai and the Achika version of "Alchemy of Love", the theme song for the
Tenchi Universe film,
Tenchi Muyo! in Love.
As the seiyuu for girl-type Ranma in
Ranma ½, she has been a part of the singing group DoCo, and has participated in other anime-related "supergroups" as well.
She's even done Japanese dubbing for American animation, most notably as "Little Sneezer" from
Tiny Toon Adventures.
