Calumon (Tamers)

Calumon is a digimon that appeared in most episodes of season three but had no tamer. Calumon helped Jerri at the end of season 3. Calumon also has the power to Digivolve other Digimon to the next stage. He holds the power of the Catalyst which makes the Digimon Digivolve. The Digimon Soverines made Calumon so they could protect the power to Digivolve. Near the end of the series Calumon releases the Catalyst forcing all Digimon in the Digital World to Digivolve to Mega form to fight the D-Reaper.
