Gigaleon

is the boss of Deception Castle in. It is a floating, saucer-shaped creature with a single eye on one side and a large, pink tentacle-covered hole on the other. It uses the latter to spit out balls on fire. It is similar to the boss Margoma, in that it has a single eye that can be damaged with Bombs; however, Gigaleon cannot cover its eye. It can instead simply flip its body.

Characteristics
The Links fight Gigaleon upon a floating platform in the sky. Gigaleon will drop dark balls of fire onto the platform while flying through the air, which will burn the Links on contact. There are four wind turbines at each corner of the platform that can be activated by using the Gust Jar on them. This will create a large twister from their fans. To attack Gigaleon, the Links must activate the wind turbines when Gigaleon flies over them. This will stun it, allowing one Link to use the Gripshot to pick up a Bomb Flower from one of the platforms on either side of the arena, and throw it into the fan, causing it to explode once it hits Gigaleon's eye, damaging it.

Once damaged enough, Gigaleon will throw flames at the Bomb Flower ledges, causing the Bombs to explode and the ledges to fall. It will also flip itself over, so that its vulnerable eye faces upwards. Gigaleon now moves faster and floats above the win turbines for less time. It continue its attack by dropping flames more aggressively, occasionally chasing a single Link while doing so. The Links must again stun Gigaleon, by using the Gust Jar and wind turbines, however, since a Bomb Flower can no longer be thrown at it, one Link must be thrown into the turbine's wind instead. This will propel him onto Gigaleon's saucer body, allowing him to strike its eye with his Sword. After enough Sword strikes, Gigaleon will fall onto the platform, allowing every Link to attack it until it is defeated.

Nomenclature
Gigaleon's name comes from, meaning giant, and "leon" from Keeleon. This suggests that it is actually a giant Keeleon. Both monsters also have similar tentacles that they use to throw explosives. This is also reflected in its Japanese name, as both creatures have similar names.

Gigaleon's original Japanese name was, but it was changed as it fitted Prismantus better.
