Official Move Approval IV

[Clownpiece]

The Bossman has two variants that are at the extremes, so depending on where you want yours to fall on that spectrum it might be fine. I’d think it would be closer to the ‘small painful deterrent’ end if you want that long of a time, though. True excruciating pain and lasting damage would be closer to maybe 30 seconds – 1 minute. Does this effect start up immediately or is there a charge-up time? Does it take concentration to maintain? Both of those things would change how long it could last.

Also, though I know this is probably something you’re aware of, I have to state for anyone else reading this that this Move wouldn’t layer on any significant damage to your other moves.

Nuclear Furnace (Area Attack) (300): As a byproduct of the nuclear reactions with her, Utsuho’s normal body temperature is extraordinarily high. Under most circumstances, she can keep it confined to her core, keeping her comfortably warm to the touch. However, when she raises the output for an extended period of time, such as during a power-up, this is not an option.
Unable to suppress it any longer, her body temperature begins to rise uncontrollably, forming a shroud of nuclear heat and radiation around her body, which spreads no further than arms reach. The shroud takes about half a minute to heat up fully, in a process that is out of her control entirely, and lasts for two minutes before it begins to cool down, with the heat fading away completely after another half a minute. Though it is the result of nuclear energy, the shroud around her is nowhere near the temperature or pressure needed to cause fusion or fission, and rather is only hot enough to make being near her incredibly uncomfortable to friend and foe alike. Her skin temperature, on the other hand, increases dramatically, and contact with in this state would feel like touching molten lead.
Okuu is more than capable of resisting her own heat, but all that escaping energy leaves her exhausted afterwards. It takes her around a minute to readjust to the lower temperature and output level, leaving her cold and uncoordinated. This move requires elevated output levels in order to function, causing it to start up automatically upon activating a power-up, without giving her any say in it. Of course, due to her inability to multitask, it remains the only move that can be used during them.

Alright, 3 minutes total, with the first 30 seconds heating up to full power, and the last 30 cooling down.
It's an entirely brainless move, she has no control over when it starts itself up, so it takes no concentration to maintain.
And made it more clear that this is the only move she can use during power-ups. She's a birdbrain who can't concentrate on more than one thing at a time. Control "Self Tokamak" already says that but might as well cover all my bases.
