Hi! 🦀 here thanks for answering my idea. Here's what I imagine what would Mania form! Chief would look like;

Basically I took the 'consume' in a literal way- like- in the future Mania form! Chief consume the first ever black ring(BR-000 if i remember it correctly) or consume the Mania in the city like those contamination, corpus, Corruptors etc. Probably the Sinners but instead their suffering or manic I guess? So yeah :D I hope your doing alright, drink plenty of water, gets some rest and good night
I like this design for their Mania form, something otherworldly and unnatural in form, wholly alien to our world and understanding, not quite solid, and yet not quite gaseous, a form of matter unknown to all making up a body that defies all other explanation beyond monstrous.
I can picture the Chief loosing control as the Mania overwhelms them, shadows and mist erupting from their form as they scream and howl in agony, the shackles burning with their pain as they begin to twist and distort into the monster pictured above, a howl slipping past the beasts lips as it surges towards BR-00, where it begins to feed on the power, culminating in a monstrous metamorphosis.
I like to imagine that they also possess a human form that they can switch into, after they achieve this state of Apotheosis, their eyes changing into the symbol of the Illusory Moon as the shackles coalesce into a halo above their head, wings of dark red and black, the colors of mania, mingled with the white and blue of Hypercubes mingled with the colors as they cast an ominous glow over the Chief's surroundings.
Part of this design is inspired by an idea I have that Mania is setting the chief up to be some form of Messianic figure to use as a means of securing dominance over the world, utilizing an angelic form to make them appear more divine to humanity, but I digress on that front.
This design makes me imagine their form as being more cosmic and otherworldly in nature even when human, the wings gaining an almost nebula like quality, the reds, blacks, blues, and whites mingling in constellations and galaxies.
Their hair becomes as comet trails, burning wisps of platinum gray light with the colors Mania and Hypercubes, of Madness and Order, reflecting from within the trails of light as the hair lengthens to caress their heels with each step, their skin gaining a faint glow as their clothing mends of any damage as they begin to walk towards their Sinners, their arms outstretched as though to embrace them as their eyes blaze with power undreamt of by mortals.
I feel this change would also manifest in their mentality warping, where as the human form embodies their desire for order and stability, along with their juvenile state, with the Mania form and their altered human state representing their growth into their own desires and mania, perhaps not quite their adult hood, but the middle ground between the pair, or mayhap a fusion of both Mania and Order.
The changes of their personality could be something as mild as them becoming more selfish, more determined to achieve their own happiness amidst the world, to something as major as them becoming near tyrannical in their views of matters, disdainful of those they cannot shackle and bind to them, and seeking to spread mania to all so that they may bind all to them.
In addition to this, I feel that their powers would alter, the normal Protestats, I think I spelled that right, growing to nightmarish levels of power, a Dark Sound becomes enough to level buildings, an Empower can recharge entire squadrons of Sinners, and a Last Stand, can make an entire legion fight like the hounds of hell made flesh and bone.
The Mania form would likely possess not only these powers, but also the ability to feed upon the Mania of the Sinners and to copy and or utilize said Sinner's powers as their own, something their human form would share to a lesser extent.
A towering monster of Mania is already a loathsomely powerful foe, but one that can call forth Ignis's flames along with Kelvin's ice to cause temperature explosions brought about by super cooling and then super heating the air, along with Chameleon's Hypnotic powers and Adele's ability to alter Memories to insure that none would even be aware of just who or what they were fighting unless the beast wished the m to be, perhaps even erasing its presence entirely until it is ready to strike.
There is also the fact that having absorbed so much Mania, it is likely the Chief would be giving off enough mania to turn any person in an enormous radius around them into either a sinner or a corruptor, with the sinners being the only ones able to draw near to them, their Mania monster form would likely have a radiation field of Mania able to effortlessly envelop all of Dis in its grasp and begin to contaminate all of those present.
Beyond all of that, I feel like this transformation would mark the beginning of a complete and total breakdown of Dis as Paradeisos and the Underground are faced with the the Chief's control over Mania and Sinners, along with their own power, reaching the point of being able to challenge both of them with ease as they become the one ready to flip the chessboard betwixt the two factions as they make their own play for Dis.
Would the Chief's actions be born out of malice?
Unlikely.
But as the saying goes, "The road to Hell is paved with good intentions," and one can only imagine what the Chief would do in pursuit of any noble goal with their mind and form altered such.
Like it or not, a new age would dawn for Dis and the world as a whole, and only time would tell if it would be a Golden age, or a Cruel Age.
At least that is all I have at the moment lol, sorry for the rambling, I got carried away again.
Take care and stay safe.
