American comic publisher Top Cow has released a new Battle of the Planets comic series in 2002. But in September 2003 Top Cow decided to stop it at issue 12. A number of spin-offs has been sold as well. Like Battle of the Planets/Thundercats and Battle of the Planets/Witchblade. Mark and Jason both had their own adventure in a comic and there are also separate issues like the *Battle Book*. Diamond Comics often has more information about these comics. In October 2003 a Battle of the Planets manga of 3 issues was being shipped to the stores and Princess will have her own comic in fall 2004.
If you live in the Netherlands you can order the Battle of the Planets comic at Comicasa. And also at stores that sell American comics. Like these ones where fans have seen the BotP comic:
