From an interview with Alan Martin (writer: Tank Girl) at badlibraianship:

So, you split up the band, so-to-speak, and Jamie continues on for a while without you. Then, nada. TANK GIRL shuffles off to that wardrobe of radioactive comic book characters ruined by bad movies (see also, Crumb’s FRITZ THE CAT). So when TANK GIRL returns, with you in tow, it’s got to raise a few eyebrows. Did you officially get custody of the character whenever Jamie decided to become a pop star?

AM: There was never a conscious decision on my part to stop writing Tank Girl stories. I actually had scripts written for the second series in the Manga magazine, but I was “edited out” by the twat that was put in charge. He stuck some terrible Tank Girl strip in instead, I haven’t read it past the first few pages, I find it as galling as the movie script. I burnt all of my unpublished stuff before I left Wales, I needed to purge myself of all that, lance the festering boil, if you will. As you can tell, it still brings about a touch of the red-mist when I talk about it.

I’m sure that a few eyebrows will be raised at our return sans Hewlett, but I’ve just got to say to the nay-sayers, purists, and general grumblers that this is a character that I co-created, this is my life that it will be supporting, this is my best work that I’m putting out there for you, and if you don’t like it THEN DON’T FUCKIN BUY IT! It’s that simple. I know I won’t like Britney Spears records, so I don’t buy them. Does that make me a genius?

And remember, I’m not some Hollywood mogul, remaking your favourite Ealing comedy into a piece of shit directed by Ritchy Cunningham. This is me, I love Tank Girl, good and proper.

As for official custody, the publishing rights to the character are still owned by Jamie and myself. I run all of my ideas by Jamie first. He was very nearly the main artist on this project, but alas, someone goofed-up.

Did the time away change your perspective on the character; the comic book industry; the movie; or life, the universe and everything?

AM: Nah.
