Shukaku is characterised as a childish and short-tempered individual, and often speaks in a bombastic and incoherent manner, giving her the demeanour of a drunkard. She uses "ore-sama" (オレ様, literally meaning: my esteemed self) when referring to herself, as she expresses great pride in her own abilities, especially her sealing techniques and defences. According to Gaara, prior to her introduction, Shukaku relishes the opportunity to kill anyone in sight, even more so during a full moon.
