Iczer-Girl Iczelion

Before the likes of Saint Seiya, Dragon Ball Z and Pokemon conquering the kids in the west, it was actually Akira that opened the door and made people realize that the cartoons coming from Japan weren't what you would expect from Disney or your TV channels.
A huge flood of VHS tapes came showing animations with mature themes, absurd plots, and enough graphic sex and violence to make parents freak out... what a glorious time!
They don't make cartoons like this anymore.

This is a comprehensive list with stuff from very good to very trashy, but all in the same spirit.
Some early 00's also included.

ps: I also recommend, but can't include here, the second Violence Jack movie, A Kite and Mezzo Forte.

Glorious 80's and 90's (Supernatural, Mystery and Horror)

ADV Films, the former incarnation of Sentai Filmworks, produced most of their English dubs in Houston, Texas. However, from the late 1990s until 2005, ADV also employed a secondary studio in Austin, Texas, known as Monster Island.

Monster Island could be considered ADV's "2nd-string" studio, as many (though not all) shows they dubbed were lesser-known and perhaps lesser quality. Shipping them to MI may have been a cost-cutting move, as many of the dubs are marred by fast-and-loose scriptwriting, questionable name pronunciations, and a general sense of roughness and inexperience.
Still, a lot of them had their own sort of charm, and some are well-regarded. You can find some comments about the dubs from me on some individual entries. Some may be approaching "lost media" status, or are not commonly available online by legal or illegal means.

So if you've encountered an ADV dub from the early 2000s and wondered why the cast was full of names you hadn't heard of, or why it felt different from the average ADV dub, chances are it was a Monster Island show.

*Note: some related/sequel titles dubbed by MI are noted only in the comments, in order to stay under the 50-item limit.

Toshiki Hirano is a Japanese anime director, animator, and character designer. His wife is a fellow animator and manga artist Narumi Kakinouchi. Some of his works have appeared in the adult manga magazine Lemon People.

His directorial debut OVA Fight! Iczer One was a project that he and his friend Aran Rei brought to Kubo Shoten, and it became a hit that turned into a series. In the latter half of the 1980s, he directed OVAs for enthusiasts such as Dangaioh, Hades Project Zeorymer, and Daimajū Gekitō: Hagane no Oni, and gained a strong fan base.

Since the 1990s, he has been active as an animation director based at Tokyo Movie, where his Devil Lady, which combines elements of tokusatsu, splatter, horror, and action like Iczer One, was well received. He is also one of the original collaborators of his wife Narumi Kakinouchi's representative works, Vampire Princess Miyu series and Fūun San Shimai LIN series.

Anime about full on robot girls or girls piloting Mecha Armor (not giant robots).
