After his death, Michael Cordato faced a choice: to find the world in which he was supposed to be born originally or to spend his next eternity in the Void. Well, his choice was obvious. Realizing that his journey might be a long one, he took one rule for himself. Leaving the worlds better than he found them. After all, how hard can it be? -=-=-=-=-=- Greetings. This fanfic is about the journey of a former member (theif/torturer) of the Russian Mafia in search of his home. MC won't be a cold, manipulative bastard and will try to help others. Of course, he will not help everyone he meets, and he certainly will not sacrifice himself for the sake of strangers. I already have several worlds that he will visit, but if you have any suggestions, then write them in the comments. List of worlds: 1. Avatar the Last Airbender. 2. Fullmetal Alchemist. 3. Harry Potter. ?. Assassin's Creed (don't know which part, I'll figure it out). ?. RWBY (a big maybe, never watched the show). ?. JOJO (maybe). ?. Solo Leveling (maybe). ?. Trash of The Counts Family (maybe). ?. Winx (if I get bored, but it will get bloody). ?. Marvel universe. Final World: ? -=-=-=-=-=- Nothing belongs to me except my OC's and ideas.
