Monster Lightning Bolt Question

We've all seen this, but does anyone know what this technically is?
Is it changeable via FF6MDE as an attack?


---------------------

I'm getting closer in finding out what it is by looking through a few other attacks, such as Phantasm.

for some reason, there are 2 separate codes that lead to that same animation, 1 as a spell graphic and 1 as a weapon/monster animation graphic

I would guess the reason is that Weapon/Monsterattack pointers are shorter, so therefore can be manipulated into pointing to the longer Spell Animation data. It's notable that if you use some nonstandard Weapon codes, you will get partial frames of Spell Animations. I know that Meeple used a lot of these for his weapons in Meeple Fantasy 6 for some interesting effects.
I don't think it works the other way around though? At least, I haven't found a way to make Spell Animations display Weapon strikes or Monster attacks.
