Terrahawks - Season 1 (1983)

Zelda attacks NASA's outpost on Mars and establishes her home, then mounts an attack on Earth, forcing the Terrahawks into battle

The Terrahawks struggle to defend against the aliens' strange powers, and find they may be forced to stop the attack at the cost of Ninestein's life.

Zelda defrosts one of her monsters, Sram, who unleashes his devastating voice against the Terrahawks.

Zelda unleashes MOID, Master of Infinite Disguise, who kidnaps Hiro and impersonates him.

The Terrahawks find a teddy bear-like alien adrift in a space capsule and take him back to Hawknest. However, he is actually one of Zelda's monsters and begins to wreak havoc in the base.

The Overlander is hijacked, but the hijacker, a news reporter by the name of Darrel, is a potential security hazard for the Terrahawks.

Yung-Star devises a way to make the Cubes more powerful by combining them. Zelda forms a group of them into a gun and threatens to destroy a newly constructed dam.

Ninestein enters an old-fashioned gun fight between one of Zelda's Cubes in the Arizona desert.

Zelda gives Sram another chance to defeat the Terrahawks by sending him to hijack the Overlander, an automated vehicle that delivers vital supplies to Hawknest.

An old space probe approaches Earth, but the Terrahawks worry because it was never meant to return.

The Terrahawks pick up a capsule in space containing only a strange vapour. However, it actually contains a gaseous monster that meddles with their minds.

Zelda attacks Earth on Christmas Eve, convinced that the Terrahawks' guard will be down. However, Ninestein anticipates such a move, and all-out war erupts. Perhaps the Christmas spirit can even reach someone like Zelda.

Zelda lures Ninestein with the captured two-man crew of a commercial space transporter. When the Terrahawks electronically isolate themselves from after rescuing the men, Kate has to inform Ninestein that the mission to get him back is ahead of schedule.
