Kyoko and Yuki

As the main antagonists of iGo to Japan, Kyoko and Yuki are the two evil Japanese web comedians that tried to sabotage Carly, Sam, and Freddie's chance of winning the iWeb Award. Both groups were in the running for the award and considered each other strong competition, even intimidating the iCarly crew somewhat. On the other hand, Kyoko and Yuki feared the influence of iCarly and plotted to eliminate them from the equation so they could have a higher chance of winning. Initially, the duo acted as friends to the iCarly gang, but eventually show their true colors when they drive to the middle of nowhere, leaving the three stranded and lost, while they would try to win the iWeb Award by default (due to iCarly being a no show). However, due to Spencer and Mrs. Benson, and some quick thinking, they were able to make it to the event, and won the award. Afterwards, the siblings got arrested for kidnapping the iCarly team.

Many believe the evil comedians are Seddie shippers, when Sam and Freddie were fighting, Kyoko and Yuki gave each other a knowing look and laugh when they fight.

Kyoko is played by Ally Maki (credited as Ally Matsumura) and Yuki is played by Harry Shum, Jr., best known for playing Mike Chang on the Fox Comedy series Glee. Shum had previously appeared in the Zoey 101 episode "Trading Places".
