What would happen if Light Yagami from "Death note" wrote Saitama’s name in the Death Note? In addition, what would happen when other aspects of different anime’s worlds combined and clashed with one another. for example, if Edward Elric attempted alchemy on Tōma Kamijō’s right hand? In essence, when key elements from different story lines meet, which one takes dominance? Saitama’s (for all intents and purposes) invincibility or the absolute inescapable death provided by the Shinigami’s death note?
