George Pérez at The Pulse

With the inminent release of the first number of Legion of Three Worlds, The Pulse published an interview with Pérez.

"I like to know the individual character from the inside out instead of just drawing superficial body types. When I'm drawing reaction shots, I want to know these characters, and have a sense of how each would truly react to the situations. It helps me stay in the story and tell the story."

"[Editor] Eddie [Berganza] told me he's surprised with three versions of the Legion that I'm trying to give each of them a sense of distinction," Perez continued. "I take the challenge of three Legions and making all the alternate dimension characters -- like three Cosmic Boys -- different, stylized characters. I didn't want them to appear as the same character at different ages -- like a dual role type thing. I didn't want it to be like the Mirror, Mirror episode of Star Trek, where there were doppelgangers played by the same actors."

Perez said, "When I was working on the different eras of the Legion, I would evoke the artists who were the most established ones at that point in time. These three versions of the Legion are very different, especially the current one. Barry Kitson and Francis Manapul are totally different artists, so distinctly different that I had to find a middle ground to make this 'present' version of the Legion diverse."
