You're relaxing on a bench outside on a nice sunny day when the sky darkens and something massive crashes down onto the ground and when you look up...you see a massive high heeled foot and looking up even further you notice that said foot belongs to a blue-skinned giantess that must be hundreds of miles tall.

Nebula: "Hello, little humans!" The alien giantess says as she looks down at the city below her, not caring about how terrified and panicked the humans in it are.
