Tristan

Tristan belongs to the squirrel branch of the Mink Tribe, marked by tan fur and a hefty, bushy brown tail striped down its middle. Her hair is a pale blue, and a dark marking runs from her forehead to the bridge of her nose. Off duty she favors a ruffled yellow blouse with puffed sleeves, a two-tiered pink skirt, and red pumps. When she is working, she swaps this for a pale-pink minidress and a matching cap stamped with a cross.

Warmth defines her dealings with anyone who treats her people well. She takes her nursing seriously, tending the wounded with care, though she does hold a firm opinion that physicians such as Miyagi ought to rein in their excitement when treating patients or studying alongside other doctors. She also frightens easily around anything bizarre, bolting in a panic after she once caught sight of a walking skeleton chatting with a dragon.

Like every mink, Tristan is born with a fighter's instincts and can channel Electro to deliver electric shocks. Her real value, however, lies in medicine. Trusted by Tony Tony Chopper to help care for Duke Inuarashi, she carries genuine nursing skill that she puts to constant use through the war in Wano.

During the Beasts Pirates' assault on Zou, she was being chased by Sheepshead when Sanji's group iced the ground and tripped his mount, then fled them in fright. Once Caesar cleared the poison gas, she vouched that the Straw Hats were not Jack's men and pitched in to treat the injured. Later she joined Chopper and Miyagi at Inuarashi's bedside and asked to ride along as Chopper's assistant on the Sanji Retrieval Team, though Pedro was chosen instead. In Wano she nursed Tama, and during the raid on Onigashima she helped Chopper mass-produce and fire off the antidote to Queen's Ice Oni virus by cannon. She also watched over a bandaged Zoro, carried a shrunken Chopper after his Rumble Ball overuse, and helped care for the wounded once Kaidou fell.
