I am afraid not. Its something I did between 1998 and 2001 and I am currently reworking it. As I complete them I will post them here if you like. I did it merely for my own urge for TMNT during the dead time during winter '98 and winter '03 in the other media. This Spring I will upload a bunch of it if your truely interested. I tried to work an in-story explaination for the red sky, a way for The Shredder and eventually Krang to come back, April back at channel six , worked with stregthening continuity, and the last thing I did was an '87 series version City At War thing.
Going back to Rat King, I have read on this site oter places that Rat King is a neutral character. The only time he ever helped them was in "Return of The Fly" which saw him locate April for the TMNT after Baxter kidnapped her. I took it that Rat King helped them because he had a thing for April. He did think she had had pretty fur I mean hair.
Also, the closest we ever got to seeing Rat King and Baxter Stockman together was the Rat King split seconds before Baxter Stockman showed up with Shredder and his two henchmutants.
