BEGONE, ENEMY OF MY MASTER!

Tali:

So, I have two ideas for her, a "regular" fight and a "final" fight version. Two different songs, but I think they capture the same idea for a fight with her, and that would be HIGH ENERGY FUN!! Originally I wanted Tali's "instrument motif" that would make her stand out to be vocals, as a reference to her singing talents, but lately, I've become very partial to a synth sound, the high-pitched chiptune sort of thing, you get what I mean? Just all around a "playful" and fun sound to it.

So this is the general sound for her "regular fight" theme:

There's a bit of a "unfinished" vibe to the start, someone who is just beginning, but it picks up speed and sounds like an adventure in it's own right, with little bips and boops all around which sound almost like projectiles to me! The ending is really fast, almost overwhelming, and I think that reflects her personality well. She's upbeat, she's a massive burst of energy, she's all around you and causing trouble! But her final fight? THIS is what I'm imagining:

I think the thing is, even by the point where she's at the "final fight" stage, Tali would know she's got no chance of beating Link in a head-on fight. In terms of tanking hits, she's just no match for him.

That is to say: she'd know her strengths and weaknesses, so she embraces her role as a glass cannon, making her even more dangerous.

The fight would be CHAOTIC and EXPLOSIVE; Tali knows if Link hits her, she's gonna go down fast, but if he wants to land a hit, he'll have to catch her first! Double elemental arrows and bomb arrows rain down on the field, combos of fire and ice, explosions and electricity, and one keyed-up Yiga teleporting from place to place, staying out of range and causing you a headache at best, and grievous injuries at worse!

I can see the fight opening with her introduction, dialogue, and then the percussion hits at 00:41, which is where Tali teleports around Link so fast she's practically flashstepping, shooting rounds of explosive arrows from multiple angles that the player has to either dodge or block, something like this:

Then the beat drops, and the fight BEGINS!

Sai: Sai's getting a regular fight and a final fight sound too. So here's the regular fight:

Gets your heart pumping, doesn't it? Sai's maybe not as good at teleporting as Tali or Poni, but he makes up for it by being an utter speedster. He's definitely the most "traditional Yiga" in terms of fighting, at least at the start with his eightfold blade. I think he's also, slightly convinced he belongs in a heist movie. So I think this is a good blend of his vibes and "Oh shit, THIS GUY IS A YIGA AND NOW I GOTTA FIGHT HIM!"

Sai's final fight would probably sound basically like this:

When I think "Sai", one of the main sounds I think of is flute. Lots of it. That's his instrument, so of course there's gonna be a lot of it for him. I think if he's put in a position where it's his final fight, he's going to want you/Link to walk in thinking he has all the power here (because he too, knows he's not a tank). He'd thrive less on chaos and explosions everywhere, and more on fear, paranoia, confusion, and unpreparedness. Preferably, he'd put you somewhere in the dark, where he's striking from the shadows. He can see you better than you can see him, after all! He'll announce his presence, he'll be high above, taunting with a chilling tone. What should come across is clear: you aren't the one in control here, he has the upper hand—you are his prey, and before he kills you, he's gonna make you suffer by playing with you like a cat with a mouse. His attacks would start slightly slow, you think you know what you're getting into, this'll be a cakewalk, he's just too calm...and then he picks up speed, twin sickles dashing at you and hitting from every direction, and suddenly you realize the danger you're in and how difficult this fight is going to be. And just when you think you've figure it out, it turns out he's been hiding a few tricks (and gadgets) up his sleeves...

Poni:

Poni is...a bit of an odd case. He'd definitely have a footsoldier theme, then a blademaster theme, then a final fight...and yet, I can only provide the final, and this, which I'd say is like...his theme, just as a person:

It's not just heroic or regal or noble, but what I love about it, what I feel is "him", is that it sounds industrious. It's not just mighty, but it's building something, with sweeter and softer parts to it too, they swell with heart, turn to playful yet still diligent, curious almost, before turning back to the sound at the beginning, but more powerful and intense, reaching something grand at its peak. And I like that sound for him:) I also think his "unique" instruments would be heavy percussion and brass, as well as the two-tone block, which if I am remembering correctly, both sounds like clip-clops AND is used in Master Kohga's theme! At the same time, I think what he gains in his promotion would be heavier kakegoe and shamisen usage, support from others but a belief in himself he can hear.

Oh, and electric guitar, but not Sai's chill heist sound, but the kind that makes you realize you are going to die and feels like a punch in the face. The main thought process I would want a player to have when the fight with him starts is "OH SHIT OH SHIT OH SHIT, WHAT DID I JUST GET MYSELF IN TO?" And this? This sounds like that (at least until 03:00):

I think fighting Poni (especially in his final fight) would be like you suddenly switched to a boss fight from the game above(my first though goes to Tiger Vanguard). A fast-moving enemy that hits you like a truck and kills you again, and again, and again. Poni doesn't need tricks, he doesn't need to hide behind gimmicks. He's carrying two different forms of weaponry (meaning two fighting styles), knows powerful magic, and is mixing in martial arts so that if the first two don't get you, he'll just pummel you into the ground or kick your chest in. But one thing is clear: he is not scared of you, and he knows the full extent of how dangerous he is. The feeling is that you aren't leaving alive, and he has the power to make that happen. The strategy I would recommend employing is: LEARN HOW TO PERFECTLY DODGE DODGE DODGE and try to get as many hits in until a plot device occurs and he decides to retreat (and Link is Hylia's Specialist Little Boy, so of course it will), because otherwise, he isn't giving up until you are dead.
