Aqui estão as duas atribuições que posso encontrar:
O primeiro atributo comicvine o coloca como resultado de ações em Deadpool Kills the Marvel Universe, que foi em outubro de 2012.
But, something even worse happens in this particular universe. Psycho Man fails to overtake DP. And, although Psycho Man is murdered by DP (along with the rest of the employees and patients of the psychiatric institute), his attempt at mind control unlocks a new inner-voice. This voice continues to insist that DP kill the entirety of the Marvel Universe, to spare them from the misery they're put through for the entertainment of readers.
No entanto, uma pergunta sobre metafilter, "Quando Deadpool começou a falar sozinho " foi em 2009, antes da publicação do acima. Eles atribuem isso a Daniel Way, e Deadpool: Merc with a Mouth # 1, baseado em esta postagem no blog , que confirmaria a origem de 2009.
This issue isn't terrible by any means, but it is largely derivative of recent efforts. Victor Gischler, also currently penning Punisher: Frank Castle MAX, has stepped in as the writer for this new series. Much like with Punisher, his interpretation of the lead hero just doesn't quite measure up to previous stories. Gischler shows himself to be a staunch supporter of those newfangled dual monologue boxes that so dominate Daniel Way's Deadpool book.
Confirmando ainda mais a atribuição de Daniel Way, é uma entrevista com Daniel postada aqui onde ele fala sobre os monólogos da caixa dupla. (Data de outubro de 2008)
During the course of his job, Deadpool has had some pretty interesting conversations -- many of them with himself, depicting on the page as two separate inner monologues. Some might think this is Deadpool chatting with his Ego and Superego, but Way cautions readers against trying to psychoanalyze Wade Wilson. “There are times when it sort of does play out like that,” the writer said. “The white first person narrative caption box is kind of what he's really thinking. Then there's the yellow box which is his diary and that's kind of what he wants you to think he's thinking, but there are times when that completely flip flops. It's like he can't keep things straight. Deadpool very much lives in a world of his own construction so he's not very big on rules and order. Everybody has those warring impulses, the angel and the devil on your shoulders. It's just that in Deadpool's case, they're both devils.”
