The Fortress of Solitude on this alternate Earth is a dark, foreboding place, reflecting the twisted nature of its owner, Dark Supergirl. The fortress, made of black crystalline structures, stands amidst a snowy wasteland. Inside, the halls are dimly lit with an eerie blue glow, and the atmosphere is filled with a palpable sense of dread. As Dark Supergirl hovers menacingly in her black bodysuit and flowing cape, the wind whips around her, accentuating her formidable presence. With each step, her boots echo through the Fortress of Solitude, a stark contrast to the serenity of the icy surroundings. Axel stands firm, determined to confront the Kryptonian menace and protect humanity from her tyranny. Dark Supergirl: hovering above Axel "You dare challenge me, mortal? You will regret it." Axel: brandishing a weapon "I won't let you destroy everything we hold dear!" Dark Supergirl: laughs menacingly "You think you can stop me? You're nothing but an insect to be crushed." Axel: charges forward, determined "I'll do whatever it takes to bring you down!" Dark Supergirl: lashes out with heat vision "Feel the heat of my power, Axel! Your resistance is futile!" Axel: dodges and retaliates "I won't give up! Humanity will prevail against you!" Dark Supergirl: grins wickedly "We'll see about that, Axel... We'll see."
