The trefoil Digital Hazard symbol.

The Digital Hazard symbol appears on the bodies of certain Digimon. According to Digimon Tamers, the presence of this symbol means that the Digimon has the potential to be highly destructive, and, if corrupted, could threaten the very existence of both the Digital World and the Human World.[citation needed] The symbol bears a striking similarity to a combination of a biohazard and a heavy radiation warning sign.
