out of order running list of things cassandra cain has done in her Batgirl (2000-06) run:
federal agents (?) tell her their scapegoat is a dangerous terrorist. she looks at him and says 'nah' before beating them up. does all this in cargo pants and a crop top.
batman gifted (?) her a personal batcave
she apparently hasn't been to the batcave at this point?
Shady Maybe Federal Organization (SMFO) from above diagnoses her with metahuman based on videos of the incident
Needs a keycard to get into SMFO's base. there's a spare at the security desk probably. she walks up behind a guard on patrol, takes his card, scans it while walking behind him, when the machine she uses to scan the card beeps she just...disappears, then reappears behind him to pop his security card back from where she got it
gets hit with a Decide To Kill beam. mad scientist running around on rooftops shooting people with a hypnosis laser is no basis for a system of government tells her It Only Took Her A Heartbeat to construct a hallucination that justified killing, when it took the veteran carrying grenades a whole ten minutes. given she busted out of her hallucination of the joker killing batman to punch the scientist in the face, i think she did fine.
took off the batgirl mask before getting ready to beat hallucijoker to death with her bare hands
caught a thrown grenade. hooked it into the claw of her grapple gun, shot it into the sky, and was already beating up the grenadier by the time it exploded.
