Note: These pictures were removed by Nickelodeon. I'll have them back on the site as soon as I'm able to.
Among the pages discovered during the brief window of time that the upcoming website for the new Nickelodeon TMNT CGI series was viewable (as described yesterday) was a series of character profiles for all of the main characters. Screen caps of all of these profiles are below.
One note about about Shredder's profile is that it mentions that he has an adopted daughter named Miwa. This is interesting because we learned at last year's Fan Preview Event that Splinter, as the Human Hamato Yoshi, had a daughter that was left behind in Japan when he fled to New York. Could Hamato Yoshi's daughter be Shredder's adopted daughter, Miwa?
