Personally, here's the list of shows that would exist, had Disney not purchase the block:
-The Adventures of Bartok the Magnificent(1998-2001)
-Doctor Dolittle: The Animated Series(1999-2001)(Not to be confused with the 1970's cartoon.)
-Ice Age: The Animated Series(2002-2005)
-X-Men: Evolution(2000-2003)(OTL, it was shown on Kids WB.)
-Titan A.E.: The Continuing Adventures(2000-2002)
-Power Rangers(Various Incarnations)(1993-2006)
-Super Robot Monkey Team Hyperforce Go!(2004-2007)(Moves to Jetix.)*
*=Jetix would be a block on "Fox Family" only.
If all of those cartoons become real, then that would make the legendary Fox Kids last at least 2-3 more years, before turning into Jetix and moving to Fox Family. BTW, if there's any more ideas for shows, or any compliments on the ideas I made, let me know.
