I'm just gonna blame Beyond for this
XILLAN TRANSFORMATIONS AND VARIANTS
Kaiser Form -
Tainted Remnant of Calamitous Beasts: Long ago, the Xillan people's homeworld was assaulted by two immensely powerful dragons simultaneously. Though their battle weakened them enough for the greatest psychics alive to sacrifice themselves to slay them both, the blood they tore from each other stained both the land and the people, granting them this transformation - simultaneously weakening and strengthening them.
When achieved, the user may transform - their skin darkening to a blackish-grey, a pair of golden wings forming out of their ki extending from their back, and golden scales forming on their forearms and legs like armor. Their hair extends, their eyes turn yellow and slitted, their sclera turns black and their power skyrockets by 120 million. Furthermore, the 30 million power cap imposed upon them is lifted, allowing them to train to 100 million in their base normally. Furthermore, one's psychic power skyrockets - becoming five times as strong as it was before, with no limits imposed on it by the form.
However, this power comes with a cost - by accessing the form, the 'draconic' parts of the user begin developing a mind of their own. Their greed's and lusts, their desires and their anger come together and gain a 'sapience', becoming what one could call a 'reflection of the original'. This 'reflection' desires one thing - to become the dominant aspect of the person. Thus, anyone who achieves the form must, sooner or later, face this 'reflection' within their minds and overcome it - either destroying it completely, or casting it down voiceless into the depths of their mind.
Hell Kaiser - The Beast Freed: A vanishingly rare version of Kaiser Form, for good reason. Only attained when the 'dragon' side of one's mind wins and takes over, the form gains several key changes - the gold scales gains a reddish tint, the wings are shot with veins of hellish scarlet, and the eyes of the user become like flame, a shifting blaze of orange and bloody crimson light. In this state, the Kaiser Form's power begins to grow - seemingly slowly, but without limit, so those facing this will find themselves overwhelmed if the fight drags on too long. Furthermore, the state grants a completely new power - the ability to 'drink' the power and vitality of all living beings. Starting out, this is restricted to touch, but given enough time one will find the Hell Kaiser creating a draining aura around oneself. Ki, PSI, Magic, even the soul - all can be drained, and consumed. However, this drain does grant one vital weakness - certain attacks of sufficient 'purity' can exploit the draining effect, poisoning and lethally weakening the Hell Kaiser. Thus, it is recommended that the Spirit Bomb be employed against any of these one encounters.
Weighted Kaiser -
Enhanced Remnant of the Beast: A 'technique' that could be better considered a transformation, discovered mere centuries after the form itself. When activated, one's sclera turns a light grey color, and the scales on their body turn a more whitish gold color.
In this state, the transformation's power triples in intensity and power - but, their psychic abilities and quirks can no longer be externally expressed, for to achieve the form one must devote all their will to increasing the performance of the form - pouring one's PSI through every muscle and vein like a river of Will. Thus, while useful for one searching for stronger Ki attacks, many psychics would discard this form as 'wasteful' and 'unneeded'.
Perfected Kaiser -
Tamed Remnant of the Beast: Another enhanced version of Kaiser Form, achieved when the 'shadow' in the user's mind is defeated. When that happens, one finds certain limits removed from the form - now, one's base state can increase in power to 315 million, with the transformation's power trainable to 575 million for a total of 900 million. In this state, the ki in one's wings becomes denser, taking on a state more like flesh-and-blood wings to the eye. One is capable of achieving Weighted Kaiser in this state, at a weakened level of X2.5.
One problem that no-one has yet to discover, however, is that if one totally destroys the 'shadow' in their mind... this is their limit. They cannot grow any stronger beyond this.
