Uhm, well... The Turtles, Splinter, Shredder April, Baxter, the Mousers, Casey, Rat King, Leatherhead, Usagi and the Triceratons are characters in both. There's a character named Metalhead and Krang is more or less an Utrom. #1-7 and Raphael #1 were arguably loosely adapted. While the Neautrinos themselves don't appear to be based on anything in particular, their cars certainly seems to be. The Technodrome does seem like an overhauled version of TCRI (probably more toy friendly). Oh, and the Transmat does appear towards the end.
Beyond some parallels that seem unintentional, that's about it. The only other direct similarity I can see is the "anything can happen" spirit.
