Inque

Inque is the secondary antagonist of season 1 in Batman Beyond. She is a shape-shifting saboteur, mercenary, and assassin.By default, Inque appears as a young woman of Eastern-European descent of medium height in a seemingly skin-tight black suit with blue hues that present an almost ripple-like design with long black hair, and a faint blue skin tone. During a mission or in battle, Inque assumes a more surreal form that possesses an exaggerated hour-glass figure and three digit claws. Her face and head is reconfigured to feature a white oval that takes up nearly half of her head that serves as her eyes while also hiding her identity. Inque is a very deceptive and cunning adversary and is not above using seduction tactics to lure others to do her bidding.

She is also shown to be flirtatious, especially in her encounters with Batman, and it is alluded she possesses some degree of sadomasochistic tendency. Yet, unlike most other classic Batman villains, Inque is much more practical and ruthless in taking down her enemies and completing tasks as a mercenary, not taking any chances for an efficient kill, nor does she possess the traditional arrogance or psychotic malice seen in other rogues in the series. Inque can be vindictive, focusing on having revenge on Batman after her many defeats by him.

Beneath her cold exterior, however, Inque has a genuine caring maternal side for her daughter, Deanna Clay. In spite of this love not being reciprocated later on, Inque still loves her daughter and wants only the best for her, not even bothering to seek revenge for her betrayal.
