1x17 - Fantastic Four

On a remote planet, its inhabitants are fighting against Blastaar and are able to banish him. Reed and Johnny enter the dangerous space zone via dimensional transport. As they depart, Blastaar escapes and follows them. Blastaar is too powerful for the four to handle. They lure Blastaar into an evacuated atomic power plant, where they use some atomic matter to put him in a coma. They eject him through the dimensional transport back into the space zone.
