FALSE SUPER SAIYAN (Patreon)

A hidden Saiyan form: it can't be bought, it shows up in no menu, and you can't trigger it yourself. It's born from rage, when you're on the brink of death and haven't reached Super Saiyan yet.

Requirements for the rage meter to start filling:

Be a Saiyan and be alive (not a spirit in the Otherworld)

Level 100 to 199

No super form unlocked (once you've learned Super Saiyan, this form is no longer for you)

Be in base form: no transformation and no stacked form active (Kaioken included)

Be at 20% health or lower

Not knocked down: during a Zenkai knockout the meter freezes

Not be a Mutant (Mutants have their own rage meter)

While it charges:

The red meter fills on its own (around 15 seconds), and fills faster when you deal or take damage

Your aura lights up, your hair rises and your ki refills by itself, as if you were powering up

Heal back above 25% and it stops charging, then starts draining

The transformation:

At 100% you transform automatically

Golden skin, white eyes, Super Saiyan-shaped hair dyed deep red and a permanent yellow aura

Power sits slightly below Super Saiyan

Once transformed, health stops mattering: only the meter counts. Hitting or being hit refills it; if nothing happens it drains, and at 0 you revert to base

You can't power down at will or switch to another form while it lasts
