Susanoomon

Susanoomon is a Wizard Digimon whose name and design are derived from the mythological Susanoo. It is sometimes referred to as "Susanomon" in American Bandai materials. Told of in Oriental legends, it is the strongest destructive god and the god which governs over regeneration. It is told that when the Network System descends into chaos, it will erase the existing system, and create a new one. It wields the "ZERO-ARMS: Orochi", which emanates a gigantic sword of light.

Digimon World 4
Susanomon can be obtained with Agumon or Guilmon, you must do the "seal the ghost" extermination sidequest in very hard mode breaking a "Defence Rom Delta" in the cave. With Veemon or Dorumon you must do the "Card retrive" sidequest in very hard mode with only 1 hp of life without recovering hp or using a gate disk. This is commonly done by falling into a quicksand pit right before the boss (dropping you to 1 HP) and then beating it without getting hit or healing.
