First appearing amongst other sidekicks in Aunt Harriet's Daycare Center, Cassandra doesn't join the others in dressing in Robin costumes, instead motioning that she preferred to be like Batman.
When the daycare children all went to the Batcave, Cassandra gravitated towards the Batsuits where she gave Alfred back his signed picture of Dan Didio. In return, Alfred gives her a Batgirl costume which she wears to scare Barbara Gordon when she arrives to pick up Tim and Jason.
When the costumes of the Bat Family are turned pink after being mixed in the wash with the red capes of the Super Family, Robin has trouble adjusting to the new color. When he is brought along on a trip to the toy store with Raven, Barbara and Cassandra, only to discover it was to the "Pink Aisle", Robin snaps into a running tantrum that is abruptly cut off when Cassandra uses a Batrope and Batarang to trip and tie him up.
Following this, Cassandra is present when Robin meets and is repeatidly defeated by the League of Just Us Cows as he attempts to obtain Batcow's cape and she is also invited to Barbara's Batgirl party alongside Stephanie and Betty.
When Huntress' Birds of Prey soccer team takes on Lobo's Secret Six, Cassandra watches the match from the bench.
