Curate, connect, and discover
(Hopefully final) UPDATE:
When I made the last post, I only looked at the attacks that the wiki said gave the "Zap" attribute, when searching for other instances of electric attacks in Star Allies. This means I only checked the movesets of playable characters and not any bosses (aside from Zan Partizanne).
So! Quick lightning round (hehe) of updates: Kracko does have one attack with pink lightning, but it basically looks like Taranza's Sectonia attack, so Magolor's Dark Electricity is still unique. Void Termina has the usual yellow/green/blue electricity (like allies with the Zap attribute!).
More importantly, however (and the reason I made an extra post), is Hyness.
Now, Hyness' electric attacks are nothing of note--they're the same yellow/green/blue colour as nearly every other electric attack in the game. However, take a look at these two other attacks of his instead:
For comparison, here's Magolor's again:
The two attacks are nearly identical! The only differences are the trails behind them, and the little lightning bolts inside Magolor's spheres that Hyness' lack (which makes sense! Magolor's attack is electric-elemented, while Hyness' is elementless).
So, what does this mean? I've got two ideas:
1. Purple is just the colour of generic, elementless magic.
It does make sense? Like, if I were to pick a "generic magic" colour, it'd be either pink or purple.
This also fits in with how Magolor's magic bombs in the Epilogue and his Deadly Spikes are purple and elementless.
It does mean tragic things for how much my "Magolor's magic was corrupted by the Master Crown" theory/headcanon is supported by canon though </3 Still gonna stick with it regardless though, since it still does make logical sense for something like that to happen.
And even still, that still makes Magolor's electric spheres really weird, and this time it's in a way that I can't find an explanation I'm fully happy with. His spheres are electricity contained inside a shell of generic magic. Why? None of Magolor's other spells are like that. No other magic in general is like that in Star Allies (aside from potentially Taranza). It's perfectly possible to create magical balls of pure electricity, as proven by Zan Partizanne, Spark, and Beam. Does that mean Magolor is actually worse at electricity than other forms of magic? So the spell needs to be mostly Generic Magic with only a little bit of lightning encased inside?? But then why is that attack (which is still electric-elemented) the only spell he can still cast when he loses everything in the Epilogue? If he was bad at electricity magic, it should be one of the last things he relearns.
Taranza's similar magic spheres are also just Generic Magic, I guess (again, following Star Allies where the attacks are elementless). But maybe they also have some other type of magic stored inside them, hence why they glow? Or maybe it's just a higher concentration of magic in the orb that causes the glow, which is also why the attack is more solid (it bounces off walls) and more opaque than Magolor and Hyness' spheres.
2. Purple is the colour of dark magic.
Supporting evidence: Hyness' spheres look very similar to the giant Dark Heart in the background, which we know to be composed entirely of negative energy and is generally strongly related to Dark Matter/dark magic
Hyness also declares himself and his cult and/or species to be "masters of a matter most dark" during his rant before you fight him.
Magolor's spheres, then, are a combination of electricity and dark magic, while Hyness' are pure dark magic! Which works with my original headcanon/theory! Magolor's main magic spheres pre-possession were entirely made of electricity, but the corruption and soul-eating from the Master Crown permanently infused dark magic into the attack (and also permanently tainted his magic in general).
Like I've said before, in my opinion, the reason the corruption only shows in his electric attacks and not in, say, his Revolution Flame or wind-elemented Magolor Surge is because electricity magic is his natural inclination. It's the type of magic closest to his core being, the ability he can summon with very little effort. Fire and wind magic, meanwhile, is comparatively more difficult to cast, since it's further away from his core. The specialized form his magic needs to take on for those types of spells kinda diminishes the effects of the Dark Matter corruption, at least in appearance. I could see all of his magic having a slight effect similar to dark magic/Dark Matter's attacks in addition to whatever element the spell is actually supposed to be, too, though.
Maybe Dark Matter's magic, while being elementless/dark magic, is also closest to electricity out of the 'natural' types of elemental magic? Considering how the Dark Lasers do resemble lightning, even if the attack isn't actually electric. So maybe it's also easier for Dark Matter to 'infect' electricity magic compared to the other elements, I dunno.
This would also suggest that Magolor's Deadly Spikes are also dark magic, which is fine by me, actually! With some of his magical skills in the Epilogue (specifically Levitation, Magolor Surge and Magic Bomb), Magolor specifically says that he used to be able to use them before he lost all his powers, and is glad that he can still do them when he gets those abilities back. He does not say that for the Deadly Spikes, though! So it's fair to say that he learned that attack for the first time during the Epilogue, and wasn't something he ever knew how to do previously. And so, the reason he can use a dark magic attack like that at all could be due to the Master Crown's influence and soul-eating.
His Magic Bombs, meanwhile, I'd say had their appearance corrupted just like his electric spheres were. Maybe that's even part of why he switches to his Gem Apple Bombs by the time Star Allies rolls around? It helps hide the corruption.
This would also suggest that Taranza is a dark mage! But the reason he has that ability is entirely separate from Dark Matter (which could also be why his attacks look different from Magolor and Hyness'). It's just his natural "core" type of magic, like how Magolor's is lightning! Hyness, meanwhile, could probably go either way! Given that he, like Magolor, can wield a wide variety of elemental magic, I could see him maybe being born with one of those as his "core" magic. But he also had his magic corrupted by Dark Matter---willingly, in his case---at some point in his life, in service of/to be closer to his Dark Lord. Or maybe he was just born with dark magic. I guess it could depend on whether him being a "master of a matter most dark" is a species thing or a cult thing. In any case, nowadays, dark magic would definitely be his natural inclination!
...Or I guess another option is that both ideas are true! Purple can just mean different things for magic! Like how wind and electricity magic can both be associated with green. For Hyness and Magolor, their purple magic is the result of dark magic. For Taranza, it's highly condensed and concentrated Generic Magic, which is why it's also very bright and glowy!
Anyway, yeah! I think it's neat how Hyness and Magolor basically share an attack, and I'm glad I caught that detail. I'm definitely leaning more towards that specific attack being dark magic (or tainted by dark magic in Magolor's case) rather than generic magic, since that supports my headcanon/theory better dgsgshfh. And plus it just makes more sense to me! But, I'd like to suggest all the possibilities I can think of, in the interest of fairness!
Thinking about how Magolor's electric ball attacks look nothing like any other instances of electricity in the games that I can recall (particularly in Star Allies), but do resemble Gooey's Dark Laser attacks quite a bit
