Galacticmon

Galacticmon is an unknown level Digimon whose English name is derived from "Galactic" and whose Japanese name comes from the Norse Ragnarök, an event that depicts the death and rebirth of the world.

Digimon World 3
Galacticmon is the final boss of the game.

Galacticmon is an incredibly huge cybernetic Digimon, resembling some sort of spacecraft. It is formed after the Gunslinger satellite is merged with Snatchmon and given life. Galacticmon's head alone towers over even the largest Mega Digimon, and during one cutscene it is shown in orbit above Earth, further adding emphasis to its sheer size.

Galacticmon appears to carry at least two giant missile silos in place of legs. Whether these are engines or indeed weapons is unclear. Galacticmon's tail contains a smaller head at the tip, and the tail is lined with solar panels which were once the power source of the Gunslinger. It also carries the Gunslinger's ultimate weapon, the Ragnarok Cannon, but this weapon appears to be significantly weaker than in its original state.

It appears to have a maintenance system including skeletal metal hands which it uses to attack and block with during the fight against the head.

When Junior fights Galacticmon, it is fought in two stages: its tail and then its head. Its tail attacks simply with physical attacks: a stabbing motion like a scorpion and a beam that fires from its tip. Once the tail is defeated, the body intervenes and uses Ragnarok Cannon to reduce Junior's current Digimon to 1 HP. The head then comes into battle, with the ability to copy one of Junior's Digimon techniques, which it will fire in a small beam from the head. Galacticmon can also smack Junior's Digimon with its hands or launch a giant, wind-based beam.

After Galacticmon is finally defeated, it explodes and falls to Earth as a meteor shower. Galacticmon's true plan is to merge with planet Earth to become Gaiamon.

Attacks
 * Ragnarok Cannon: Fires a massive beam from the Ragnarok Cannon on its chest.
