Snatchmon

Snatchmon, an unknown Level Digimon. Its level, much like those of its higher forms such as Galacticmon, is in dispute, according to Lord Megadeath, Snatchmon is born when four Vemmon fused together.

Digimon World 3
Snatchmon is an antagonist. It resembles a purple humanoid, with a large visored helmet and a thick, curling tail. It broke free of its master's control and absorbed him after he refused to be a slave to anybody. Snatchmon claims to be the most powerful Digimon ever, and given his ability to merge his data matrix with technology, this may very well be true. After a short dialogue sequence, Snatchmon fuses with the Gunslinger satellite and becomes the mighty Galacticmon, the final boss of Digimon World 3.

Snatchmon's attacks are not known, but he is shown to absorb other digital lifeforms to further sustain himself.
