Vincent Valentine
"A mystical man, stern and upright while at the same time dark and mysterious..."
When picking the hero of Final Fantasy VII, Cloud was surprisingly not the obvious choice, in fact, Cloud and Terra were the last two of the main character to be revealed, more than likely due to the amount of noticeable characters in their respective games. My guess, they probabaly were considering Vincent for the job, not only does he have a wide fan base as it is, but he has been in every single Final Fantasy VII game, even Before Crsis which noticeably lacked Cloud at all (although in Crisis Core he only got a mention but no face time, it could at least be considered a cameo).
Vincent would be a
Chaotic Barrage player, able to use his agility, sharp claws, and quick marksmanship to quickly ruin enemies and put himself ahead. By default most of his ranged attacks would not very powerful but they would be fast and usually come in barrages, whereas his claws are stronger but are very close range.
Alternative Costume: Turk. It's one of Vincent's already established alternative costumes, and I think its much better looking than just a pallet swap. Vincent would take up the suit of his former profession as a Turk, although he would have red eyes, and possibly either a claw or some hand-weapon to make up for the lack of claw he has in his normal costume.
Brave Attacks:
Berserk Dance (Ground): Rushes forward and slashes at the opponent with his claws several times, finished by blasting at opponent and sending them back a short ways.
Livewire (Ground): Charge shot, attack changed with how long its charged. Short short shoots out three short range projectiles with electrical feedback. Medium charge sends out a burst bullet that explodes short range, causes absorb and damage. Long charge sends out a quick bullet towards foe, that bursts on contact, long range, but explodes if it hits the wall or other object before it hits foe.
Splatter Combo (Aerial/Ground): Starts to slash at foe, performing many low damage strikes before launching foe into the air, If you press forward + O you can chase foe for additional claw strikes before shooting them away, if you press back + O Vincent instead shoots a barrage of bullets at the airborne foe, connecting with several range shots, if you only press O Vincent will leap to slash twice more before firing into opponent at point blank range.
Chaos Saber (Aerial/Ground): Shoots out six quick slight homing projectiles from gun which appear as blade-like projectiles, flies into foe, and then doubles back to hit again. Has the chance to hit only once forward, once on return, or hit on both forward and return. If return bullets hit, can initiate chase sequence.
HP Attacks:
Beast Flare: (Aerial) Fires out four shots, explode at mid range if they don't hit the opponent first, good spread for a close-up attack, but can be dodged back.
Gigadunk: (Aerial/Ground) Slashes forward and then leaps over foe, before sending a huge percussive shot downwards into enemy for HP damage. If slash misses, Vincent will still leap over foe, but its easier to dodge then. If connects, easy Wall Crash with floor.
Nightmare: (Aerial/Ground) Creates a vortex of wicked souls, pulling the enemy in. Absorb and projectile protection.
Satan Slam (Ground): Shoots ground several times forward, east shot chasing after foe to strike at their feet. If foe is on the ground or close enough to ground where a shot strikes, the ground bursts open and absorbs foe, causing damage.
EX Mode: Dirge of Chaos. Vincent takes the form of Chaos, the title a take on Dirge of Cerberus, Vincent's solo game. Although there are two designs of Chaos to choose from, I think the one from Dirge of Cerberus is more well polished, not to mention the fact he retains his gun and claws makes it easy for him to still use his regular moves while in EX Mode. In this mode he gains Regen, as well as the ability to Glide, thanks to his demonic wings. In addition, Vincent equips two Materia, Deathblow Materia, which increases the power of his attacks, and Speed Plus Materia, to increase his movement, making him a force to be reckoned with.
EX Burst: Death Penalty. Vincent will descend upon the enemy, slashing at the enemy brutally with his claws, before leaping back and charging his ultimate weapon, Death Penalty, collecting the souls of the wicked for a final strike. Command input, not sure what kind, maybe O pressing like Sephiroth and Cloud have, will charge up the soul stealing weapon. If successful, Vincent will use Soul Shot, a blast from the energy of the gathered souls to do chain Brave to HP damage. If the input command fails, Vincent will instead use the power he has collected to shoot the ground, performing a stronger version of Vincent's Satan Slam, his strongest attack from Final Fantasy VII
1st Weapon: Quicksilver
2nd Weapon: Cerberus
Master Weapon: Death Penalty
Vincent's weapons are pretty obvious, Quicksilver was originally Vincent's default weapon in Final Fantasy VI, Cerberus replaced it come Advent Children and was his default weapon in Dirge of Cerberus. Death Penalty, also naming his EX Burst, is his ultimate weapon in both of his games, in Final Fantasy VII and Dirge of Cerberus.
