Super Insanace/False Super Insanace

False Super Insanace (疑似超イン酒梨) is a Insanace transformation that Stelar undergoes during his battle with Thantos on the Bubbles Town arc. This form was once considered the original Super Insanace, but then was re-labeled as Giji or "False" Super Insanace.

Overview
In this form, Stelar's irises and pupils are no longer visible, mostly in turn to the power and bleak rage. His body bulks up a little, his hair straightens like that of a Super Insanace, his skin color also appears to have a yellow hue to it, but there is no considerable change in feature other than a red tint to his hair (due to the reflection of the yellow aura on his black hair, his hair is not actually red). He gains a yellowish surge of aura, somewhat but not quite resembling that of a normal Super Insanace's. In a manner, it could be seen as an incomplete Super Insanace transformation. In turn, the form somewhat resembles a glorified Kaio-ken form and even makes the same sound as it. However, there are notable differences.

When he transformed into the true Super Insanace during the fight against Diego, Stelar witnessed the beating of his girlfriend, Airashi (which was coupled by the fact that Diego wanted to make Airashi his 'queen'), which drove him over the edge. This ultimate pain was not fully present during the fight against Thantos, which is most likely why Stelar did not transform fully. The form of False Super Insanace was shown to be very erratic, and Stelar did not seem to be himself because of said erraticism and his whited-out eyes.

Usage
During the battle against Thantos, Stelar's strength began to quickly debilitate. Having no more options, Stelar's anger surged, causing him to gain a massive power increase, enough to quickly overwhelm Thantos. The form faded after a while; more specifically, Stelar seemed to regain his state of mind when Thantos ripped his arm off and regenerated it. This may suggest Stelar was not in his usual state of mind, as indicated by his pupil-less eyes and his erratic attacks.

One way to put it is that the False Super Insanace transformation occurs when a Insanace has the required physical power but lacks the required mental strife to transform into a Super Insanace. It is apparent, however, that the form gives a large power increase, enough for Stelar, who was being easily beaten previously by Thantos, to now quickly overwhelm him.
