Eccentric grandma in a cybernetic combat suit, cackling wildly, shooting laser beams in every direction, striking a dynamic pose, ultra-wide angle, full-body view. Adorned in an elaborate biomechanical headdress and outrageous sunglasses, her outfit a blend of sleek technology and worn fabric. A backdrop of glowing blacklight cityscape at night envelops her. Hyper-realistic photography with incredible detail, 8k resolution. Amidst the futuristic chaos, neon lights dance, adding an electrifying ambiance.
