So... for some Gachiakuta crossover ideas again, I'm trying to think of a Gachiakuta/Final Fantasy IX crossover. Mostly the ideas of the main party if they have a Vital Instrument. I think it's fun trying to think of those.
GARNET TIL ALEXANDROS: I think her Vital Instrument could be her Silver Pendant. As for what it can do, I'm thinking maybe it basically gives her Alexander as something like a Stand from Jojo's Bizarre Adventure.
ZIDANE TRIBAL: I think his Vital Instrument could be his dagger. As for what it can do, I'm thinking maybe it basically turns him into a version of Wukong
VIVI ORNITIER: I think his Vital Instrument could be his hat. As for what it can do, I'm thinking maybe it can just give him some of the basic element forms of black magic and grow from there as he grows as a person.
ADELBERT STEINER: I think his Vital Instrument could be his sword. As for what it can do, I'm thinking that it has two abilities: when sheathed it gives him great defense but low strength and when unsheathed it gives him great offense but low speed. Steiner would need to balance his how often when sheathed or not to get use out of both parts of his Vital Instrument.
FREYA CRESCENT: I think her Vital Instrument could be her spear. As for what it can do, I'm thinking it allows her jump high and far, or maybe as far as she throws it.
EIKO CAROL: I think her Vital Instrument could be her hair bow. As for what it can do, I'm thinking maybe it could allow her healing magic essentially, maybe that and/or a calling upon a Moogle to do that for her
AMARANT CORAL: I think his Vital Instrument could be his claw weapon. As for what it can do, I'm thinking that it gives him basically a lesser version of Wolverine/Logan type of self-healing, maybe that he needs to be able to properly deal damage to enemies in order to take heal from the damage inflicted.
QUINA QUEN: I think their Vital Instrument could be their fork. As for what it can do, I think it could allow them to copy the power of anybody else's Vital Instrument at least for a short time, so long as Quina is able to poke the target with their fork.
...And so, that is all I got this! Maybe at least for the time being, as I feel like I could come back to this at some point just to update this better. I still need to finish my playthrough of FF9, just to help in my experience of that game's world and the main characters. I feel I should also get into a full watch of Gachiakuta or get my hands on the manga just to maybe get more of an idea of that world, the characters, and how Vital Instruments work.
