As a young warrior, Blackfoot was a bully, critical,[36] but popular among his Clanmates.[37] Yellowfang described him as strong, but not a clever fighter,[38] though he would battle fiercely despite injury.[39] As deputy under Brokenstar and Tigerstar, Blackfoot was obedient to their authority, even when obeying meant breaking the warrior code.[36] However, he never admitted to regretting what he had done.[40] Upon becoming a leader, Blackstar was hesitant to ally with the other Clans[41]
