"Moon dust soft and pliant, send to Earth a giant!"
- Rita's incantation for summoning Giant.
The Giant was a knight, armed with a sword. Unlike the other monsters sent by Rita, the Giant was already giant; (the other monsters being destroyed and then being made giant. This may also be why his name was Giant). Also unlike other monsters, the Giant did not show any abilitty to speak.
Giant was destroyed by the Tyrannosaurus Dinozord.
