Biography[]
In "Bubblevicious", Professor Utonium used the hologram room with The Powerpuff Girls. Buttercup used the Hologram Room to beat up a Giant Slug Monster. She went completely psycho and slammed that monster to death. Professor Utonium congratulated her on her excellent work, but Blossom criticized her for being "too harsh" and "going overboard" with the violence. When Bubbles took her turn, The Professor cranked the machine's danger level from a 9 down to a 2, giving Bubbles a remote control robot to fight. Bubbles didn't like this, as it seemed condescending and she wanted more of a bigger challenge.
At night, Bubbles snuck into the hologram room and cranked the danger level up to 11 to prove she can be 'hardcore'. She fought an entire league of giant, horrendous monsters all by herself, and completely murdered all of them, proving to herself, that she was no baby, and she deserved better challenges.
In "Breaking Bliss", Bliss used the hologram room to fight off Tyrannosaurus Tex, in a test to help her control her powers.
