User blog comment:Alexandra.roybal.7/Why didn't Mona Lisa come out in the 2003 TMNT series?/@comment-6028837-20140111020722

mona lisa was a creation of the 1987 show, and the 2003 show did'nt have the kraang they had the utroms, the utroms are the alien race that appeared in the original mirage comics the kraang and krang are based on them. and the same goes for leatherhead he was also in the original comics, the 2003 show was pretty much an animated adaptation of the original comics. also we might see mona lisa in the new show they have brought in lots of 1987 stuff in the new show like mutagen man, baxter fly etc. so we might get mona lisa, hopefully.
