Whisker and his crew were employed by Nega to steal the Chaos Emerald from Sonic the Hedgehog, Tails and Marine the Raccoon, which Whisker's top agent Johnny did successfully. The trio later met up with Blaze the Cat and tracked the villains down and confronted them. What happened next remains unknown, but according to Marine she "went all crazy on them and saved the day!" Nega and the pirates may have also been connected to the disappearance of Blaze's Sol Emeralds that led to her meeting with Sonic. When Metal Sonic attacked the residents of Southern Island, Blaze initially suspected Whisker and his crew of being responsible, but this was proven to be false. (StH: #160, #161, #180, SU: #1)
