This whole thread reminds me of a twilight zone ep called the invaders where in the giant has size and location on there side while the Tiny’s have advanced science and tech to more than level the playing field. Giant try’s to leave house tiny has mag locked the doors and windows he try’s to call for help the lines are jammed he try’s to shout for aid all the speakers in his place start playing the latest pop songs at full volume. Doors are no match as she has ways of cutting or blasting holes to enter or escape out of a personal force field keeps them safe from harm a holo projector to camouflage when people come to investigate. Plot twist it’s not a invasion force just some collage students doing a theorist on first contact with a alien race the story ends with giant committed and aliens getting there degree
