Hm... been reading too much Exalted, and got inspired by Luna. Her creation myth of dominating, slaying, and seducing the other potential moon goddesses sounds like i could be an interesting way to play this, since we're a seething storm of souls that don't generally enjoy being quiet most of the time. After all, we've already got probably a few dozen
Wrote up on a whim. You don't often have the opportunity for the losing vote to speak up in game, and I like the idea of the various factions for voters being subsets of Nemo's souls amusing.
[]What do you look like?
Your appearance is mercurial, shifting in response to the seething souls within you. You appearance is generally thin and androgynous, hair as white as the moon above when the storm within you is balanced.
When the more vicious souls scream for blood, your hair reflects their crimson thirst. Your body swells with barely contained bloostlust and strength, and some would scarcely think you were anything but a bloodthirsty monster, barely above your base nature.
When the sadder souls hold sway, darkness sweeps across your features, settling around you as a mantle as powerful as any battle aura, creating a domain of despair and melancholy. Those to weak to endure often take their own lives, offering them as a balm against the indescribable pain you carry always.
When the wisest of souls influence you, you become stoic, shrouding your face as you separate from the realm , seeking greater power through patience and reflection. Though you rarely act while engaged in this hermitage, those few acts you feel compelled to take often snowball into something greater than brute force could manage.
When those that were your enemy unite against the rest of you, you take a taller, more regal appearance, the seeming of a young noble settling into you self, your sword feeling like it is an extension of your body. Rare is it that the shinigami you devoured dare show even a trace of themselves, but you cannot dispute the power it grants you, even at the cost of abhorrence at your very existence.
[] Energy Manipulation
[] ???-Type (Probably trick)
Like the lone Gillian who managed to join the ranks of the Espada, you can draw upon the power of those you devoured t reach your current form. Unlike him, some of the souls were not wholly subsumed, allowing you to use their powers as your own, improving them with you own power, tempering them with your wisdom and experience. While less efficient than most releases, it allows you to choose from a collection of options, rather than be limited by a single form like others.
Drawback: Mental Break
Not all of the souls in you will yield their power to you so easily. Much like a shinigami must subdue their sword spirit, you must make them accept you as the true master of your shared body, not relying on the limitless power you have consumed from others. Should you ever fail against one of your lesser souls, it is entirely possible that you will revert to a Menos, or be completely subsumed as a new Hollow is born from your rebelling flesh.
Origin:
[] Gillian Origin
Seems the most appropriate for this build.
Again, the basic idea behind this is a similar origin to Luna from Exalted. You conquered the souls you devoured, but didn't completely wipe them out like most other Hollows did. Instead they exist as aspects of yourself that can be drawn up when they're needed, giving you a lot more flexibility than most Arrancar,who only have one resurrection. Of course, the Jack of All Trades stye does have its drawbacks. If you can't find a way to exploit your opponent's weaknesses, your strengths are lower in comparison to their own. That's not even touching on the fact that a lot of your sub-selves would probably want to be behind the driver's seat instead of letting you call the shots.
Looks like I migth have missed the deadline, but still throwing it out there. Did not see nearly enough Hollows struggling to control the sols under them, and the idea of arguing with ourselves IN CHARACTER is just too amusing to pass up the opportunity.
