The Giantess Mercy meme stems from the Overwatch community's fascination with the hero Mercy, often portrayed as a protective yet imposing goddess figure. Using Source Filmmaker (SFM) or Blender, creators rendered Mercy in massive proportions, looming over cities or smaller characters. While it originated within niche fan communities, it quickly evolved into a broader meme format used to illustrate overwhelming power, maternal dominance, or the feeling of being dwarfed by a specific situation or entity. It is frequently used to represent anything that feels impossibly large or inescapable in a humorous, exaggerated way.
