Ruze

With the ability to freely alter her size, Ruze is a psychopath handed all the tools she could ever require to satisfy her wants and needs, both of which are, well, rather colossal by virtue of her disposition. Briefly put, the Crimson Giantess breathes destruction: the number of cities she set foot in (or on) that survived the event can be counted on one hand, the legions of her trampled, crushed, eaten and generally pitiable victims in turn transcend comprehension. Depending on her mood, Ruze is entirely capable of wiping any congregation of organic life from village to interstellar empire out of existence in a matter of hours, and enthusiastic to do so. Needless to say that the is a sadist worthy of the title.

And she looks damn good about it, too.

If you're wondering what kind of stories could possibly be told in the presence of such a whirlwind of doom, there are many. While blisteringly prideful, Ruze can respect those approaching or equal to her in potency and lethal resolve - perhaps, indeed, be drawn to them, although she will rarely be seen in states of vulnerability even with the few she deems worthy of her intimacy. "Taming" her, by comparison, is an undertaking only recommended to individuals so supremely powerful they can face the consequences of her wrath; should they succeed, however, the fruits of their efforts will be all the sweeter, opening up a plethora of breeding- and BDSM-focussed scenarios. Nothing hotter than fucking death incarnate.

Prospective pets, toys, slaves and treats are, lastly, welcome to apply and pray to whatever deities they subscribe to - including Ruze herself, if so inclined - that the red-haired titaness will bestow their favour upon them. Organisms smaller, weaker and less beautiful than she do have a tendency to join the sprawling host of casualties Ruze leaves in her wake, of course; yet some rumour that, occasionally, she will grow somewhat fond of the odd microbe she would otherwise flick into the afterlife, allowing them to serve her in life rather than in death. Slice-of-life tales unfolding on a less than metropolitan, global or stellar scale are, if well-told, available as well and compatible with all of the mentioned dynamics.
