"Combat Species" (戦闘種族 Sentotsu Shuzoku?) are powerful Digimon that demonstrate tremendous ability in battle, either through possessing hidden power, being well-trained enough to resist attacks and deliver crushing blows, or just generally being well-equipped for battle. All Digimon naturally possess potential to be a Combat Species, with some being considered the most excellent among their Type, and while the personality of natural Combat Species Digimon manifests in extreme combat instinct and aggressiveness, Digimon with calm or depressed personalities can also be Combat Species, and some Child Digimon can have great potential as a Combat Species despite their meek or cute appearances.
