Trial by Fire (2006)

While attending a charity event, Johnny inexplicably disappears. He finds himself in a stadium filled with aliens, where he has been put on trial for crimes against the Kree empire, with Ronan the Accuser acting as judge. Reed and Sue find the stadium and try to act as Johnny's attorneys, while Ben attempts to entertain the guests at the charity. Unfortunately Reed and Sue's testimonies fail. Even Ben is no help, after he is retrieved from the charity. Johnny is sentenced to immediate execution by robotic creatures. Ben, Sue, and Reed fight the robot executioners, one of which is accidentally thrown into the crowd. Johnny protects a Kree child in the audience from the errant robot, which inspires the crowd to demand Johnny be exonerated and released. Feeling humiliated at having to appease the crowd, Ronan releases Johnny. The Kree return to their home world, whereupon Ronan is banished from the Kree empire, while the Supreme Intelligence notes that the Fantastic Four may be useful against the Skrull. (NOTE: In this episode, the opening theme music has been pitch-shifted to a noticeably lower key.)
