VENGEANCE IS MINE!
As Yon-Rogg once more plots against Mar-Vell, Mar-Vell takes Rick Jones to the nearest city, and allows Rick to switch places. Entering into a bar, Rick finds the desire to play music for the audience and manages to convince the music act to let him have a go on stage. The crowd reaction is mixed, and Rick is forced to knock out a heckler in the crowd. However Rick grabs the attention of music promoter Mordacai P. Boggs who offers to set Rick up with gigs and promote him, an offer which Rick declines. Afterwards, Mar-Vell deduces the location of Yon-Rogg and Rick switches places so they can go into action as Captain Marvel.
Yon-Rogg has taken Carol to another abandoned Kree outpost on Earth, where there is a Psyche-Magnatron, a device that has long since been banned by the Kree empire. Yon-Rogg uses the device to create a Mandroid robot. When Mar-Vell arrives to save Carol, he has to face both the Mandroid and Yon-Rogg. During the battle Carol is injured and the Psyche-Magnatron damanged. Mar-Vell destroys the Mandroid and manages to escape as the Psyche-Magnatron explodes, killing Yon-Rogg in the process, but Mar-Vell manages to get far enough away that he is only mildly stunned by the blast. With the battle over, Mar-Vell changes places with Rick, who is just as physically exhausted as Mar-Vell and collapses on the ground.
