She is skilled at handling a motorcycle, grappling hook and various gadgets. Has some minor training in various forensics and detective skills. She received erratic training under Robin III, Batgirl II, Oracle, Black Canary, and Batman. Batman has trained her in escapology and stealth.

For a significant time as Spoiler, she operated by herself and took down her criminal father a couple times.

Weapons & Equipment Robin gave her weapons such as smoke bombs to use when he could, and later when she got friendlier with Batman, she was able to secure the whole Bat-arsenal, including a Kevlar costume. The costume is insulated against fire, projectile, and electric attacks. Her cowl maintains contact with Barbara Gordon and monitors her vital signs.

She possessed technology that lets her turn invisible, but she abandoned or lost it when she took up the Batgirl identity.
