Gigas Family
Gigas is a Greek word for giants. In Secret of Mana there were three Gigas who were not as large as most would consider giants, but they were pretty big. They are considered to be Spirits and have the ability to break themselves into multiple flying orbs which cannot be harmed. They cannot use spells during this phase, and it should be noted that the Gigas never actually physically attack the characters. Even when they look like they are taking a strike they are actually casting a spell.
In SoM Gigas are classified as Spirits.
Fire Gigas
The Fire Gigas attacked the Earth Palace in the Dwarf town in Gaia's Navel. Gnome was afraid of the monster and could do nothing to stop him from going after the Mana Seed, so the heroes had to stop him. He uses many multi-targeted fire spells.
Frost Gigas
When Santa took the Fire Seed from the Fire Palace he turned into the Frost Gigas and took up residence in the Ice Palace. The Frost Gigas talked to the main characters telling them to go away, and it treated them like children. If the battle with the Frost Gigas is lost you will not recieve a game-over, but instead you will appear in the Ice Palace Throne Room and be ordered to leave, so some of Santa's original self is still behind the beast. During the fight he uses many multi-targeted spells and casts Ice Sabre on your characters to reduce the damage you can do to him. He has an ice breath attack that will encase you in ice and then frosty you.
Thunder Gigas
The Thunder Gigas is in the third part of the Pure Land before the Blue Dragon. He uses Sylphid spells as well as a blitz breath.
