- "I've earned my stripes. Call me- Tigress!"
- ―Tigress's official introduction
Tigress has often been vain and mean to others, likely before enrollment. When she and Carmen (then Black Sheep) first met, they did not get along. After Carmen defected from V.I.L.E., their rivalry grew stronger.
When encountering Carmen in Java, she was readying a bioweapon fungus to destroy the rice supply of Indonesia, but was stopped by Carmen's friends as she was too focused on her old rival.
She's also snarky and rude to the other classmates, especially Mime Bomb. Despite her behavior, she works with him during The Lucky Cat Caper while in San Francisco.
Sheena was already a criminal, having previously "earned her stripes", but joined V.I.L.E. to become an even better crook. She favored shoplifting, especially jewelry and expensive trinkets.
Tigress is ruthless, aggressive and a talented field agent, but also extremely vain, arrogant, competitive and willing to hold a grudge. She is equally unpleasant to allies and enemies alike, and if she takes a particular dislike to someone (such as Carmen/Black Sheep) she goes out of her way to belittle, demean and taunt them, which sometimes causes her to waste valuable time. She also underestimates her opponents on occasion. However, she isn't completely without gratitude.
Sheena is a physically fit, and athletic female of at least 20 years old. Her hair is either fully white or platinum blonde. She has a small beauty mark under the right side of her mouth and has baby blue eyes.
Tigress wears a mask that contains high tech functionality like night vision goggles (also making her eyes look green). She wears a catsuit that includes a pair of gloves with razor-sharp claws. She can view through anything, and use special vision modes to track targets.
- Carmen Sandiego - Former Classmate and Rival turned Enemy.
- She is based on the character of the same name from the original 1994 series; unlike the original, who was nothing more than a disguise donned by Ivy, Tigress is a separate person in the 2019 continuum.
- Kari Wahlgren also played another Tigress in DreamWorks' Kung Fu Panda: Legends of Awesomeness based on the DreamWorks animated movie Kung Fu Panda which was voiced by actress Angelina Jolie.
- She is the closest thing Carmen has to a recurring rival, as they both have a measure of resentment for each other from their days in crime school and it tends to come out whenever they run across each other.
- She has a background in gymnastics, as shown in Who in the World is Carmen Sandiego? when she does a series of somersaults in Countess Cleo's class.
- Her choice of heels integrated into her stealth suit is ragged on by Black Sheep, but Tigress claims she doesn't need to sacrifice fashion for the job, as it's the authorities that should be worried about her.
