4Kids Entertainment
 was an anime production company that was in charge of the English localization of Sonic X. Like many other Japanese animated television shows, the company heavily edited Sonic X for American viewers to satisfy broadcasting regulations and standards. Several scenes, especially those that contained violence or even death, were not shown. In addition, the deaths of three characters were censored and sidestepped and the ending to the second season was greatly altered.

After Deem Bristow's death, the 4Kids voice cast took over as the official English voice cast for the Sonic the Hedgehogvideo games in 2005 starting from Shadow the Hedgehog.

This was up until late 2010, when the entire voice cast (except for Mike Pollock, Dr. Eggman's voice actor) was replaced yet again, starting with Sonic Free Riders. The CEO of 4Kids, Alfred R. Kahn retired on 11 January 2011.

In 2012, 4Kids was sued due to a lawsuit from TV Tokyo, who accused them of entering illegal agreements that allowed them to collect royalties from Yu-Gi-Oh! without paying a portion to TV Tokyo. 4Kids filed for Chapter 11 bankruptcy and later reincorporated as 4Licensing Corporation, with their rights for the English distribution of Sonic X being transferred to Kidsco Media Ventures.[1]
