The Astral Prison

Nemex entführt Jago, den ehemaligen Anführer der Thunder Cats, in die Astralwelt. Von dort ist niemand jemals zurückgekehrt. Leo wagt sich trotzdem dorthin, um seinen Freund zu befreien.

Jaga is captured by Nemex, an evil being in the Astral World, and Lion-O tries to find a way to rescue him. Third Earth legend says that the only person who can transport anyone to the Astral world is the evil Nether-Witch. Little do the Thundercats know that Mumm-Ra and the Nether-Witch are one and the same. Mumm-Ra traps Lion-O in the Astral world, and Lion-O sets out to save Jaga. While escaping the Astral prison, Lion-O and Jaga save an old sorcerer named Brodo who has been imprisoned in the Astral Prison for centuries. As thanks, Brodo sends Lion-O back to his own dimension.

Jaga queda prisionero en un plano astral por la eternidad. Lion-O debe viajar hacia el mismo para liberarlo, aunque no exista forma de volver a su hogar.
