Cebulski used to be known as Akira Yoshida.

Marvel Comics editor-in-chief C.B. Cebulski has admitted to formerly using a Japanese pen name to write.

NBC reports that Cebulski, who was promoted to editor-in-chief on 17 November, used to write under the name Akira Yoshida. The news was confirmed by a Marvel spokesman.

In a statement by Cebulski, the comic book writer said, “I stopped writing under the pseudonym Akira Yoshida after about a year.”

“It wasn’t transparent, but it taught me a lot about writing, communication and pressure. I was young and naïve and had a lot to learn back then.”

Work credited to ‘Yoshida’ include ‘Wolverine: Soultaker’ and ‘X-Men: Kitty Pryde- Shadow & Flame’, which are both set in Japan.

Cebulski replaced Axel Alonso as editor-in-chief and relocated from Shanghai to New York for his new position.
