How would you neutralize a rampaging giantess?
By "neutralize", it doesn't have to be a lethal option. Just getting themselves and others out of any active harm. Anything within reason can be used here, you have the full strength of the US Army and the United Nations. Magic and shrink rays are excluded.
Round 1: 50ft Woman
A 50ft tall American tourist is terrorizing London's city centre. She is actively stomping on cars, already after injuring dozens. She seems to be able to run very fast, with an athletic build. Your task is to bring her back, alive, with as few casualties as possible. How would you do it?
Round 2: 150ft Disgruntled Ex
After learning that her long-time boyfriend had cheated on her, she becomes furious, and she takes a growth pill. She lost track of him after he took off, so she's tearing San Francisco apart, taking hostages, crushing any car that looks like her boyfriend's. She doesn't know that he's already a stain on her heel, and she doesn't respond well to negotiators so she's slowly getting rid of the hostages through increasingly depraved means. How do you shut her down?
Round 3: 300ft Celebrity
A 300ft tall celebrity who used to be short has used a growth ray on herself, increasing both her size and her ego. Situated in San Francisco, she's put up quite a scene, stating that she "can do whatever the fuck she wants". She crushed buildings, stomped various citizens, and ate plenty of those rabid fans who have "sacrificed" themselves to her. How do you plan to put an end to her reign over the city?
Round 4: 700ft Goddess
A horny and exquisite 700ft tall woman with delusions of grandeur has begun her campaign throughout New York. She's licked up entire streets, toppled skyscrapers, and used high-rises as dildos, often with catastrophic results for those swept away by her juices. Lethal force is authorized and advised. How do you plan on taking her out?
