The Justice League originally included Oliver Queen, Bart Allen, Victor Stone, and Arthur Curry; Clark Kent did not accept a role until three seasons later . As the team continued to appear in the series, new characters were introduced and subsequently joined the team . The original Justice League first appeared in the DC comic book The Brave and the Bold #28 (1960), and consisted of members Superman, Batman, Wonder Woman, Flash, Green Lantern, Aquaman, and the Martian Manhunter . In Smallville, the team did not make its first official appearance until the season six episode "Justice", although each member had been previously introduced individually on various episodes since season four . In the series, the team never formalized a name for themselves, although the cast and crew officially recognized the team as the "Justice League". </P> <P> Series' writers wanted to make sure the characters had similar characteristics to their comic book counterparts, but at the same time, could become a means for Clark Kent to learn about himself . The creative team attempted to stay true to the spirit of the comic in costume design for certain characters, while costumes for other characters were changed dramatically . All of the characters possess superpowers, with the exception of Green Arrow / Oliver Queen, so Entity FX was brought in to digitally create each character's powers using 3 - D and 2 - D technologies . </P>
