Finally being given major speaking roles since her debut episode, Blackfire reappears in the Season 5 two-part episode "Girls Night In" as the "new alien threat" coming to Earth, having a major role since her debut episode in the Season 2 premiere. Raven and Starfire, alongside their fellow girls, fight Starfire's elder sister in an all-out battle to stop her from conquering Earth. Starfire still wants to do sisterly bonding, obliviously regardless to her elder sister's intense dislike and hatred of her. Doing her favorite game of "Truth or Death", Blackfire further shatters her younger sister's heart by stating the hard truth: That she wished she did not have a sister.
