So I'd love to see Booker make it into PSAS, and I think he'd have a pretty good potential for a moveset, so here's my attempt at one. Enjoy!
Ground Square neutral Square - Skyhook - Performs a hook punch with his Skyhook side Square - Charge - Uses this vigor to charge a few feet in front to hit an enemy up Square - Performs an uppercut with his Skyhook down Square - Slams the ground in front of him with his Skyhook
Aerial Square neutral Square - (Same as ground) side Square - (Same as ground) up Square - (Same as ground) down Square - (Same as ground)
Ground Triangle neutral Triangle - Machine Gun - Fires a few rounds from his machine gun side Triangle - Volley Gun - Shoots a round forward in a parabolic trajectory up Triangle - Heater - Shoots a very strong shotgun blast diagonally upward down Triangle - RPG - Shoots his RPG directly at his feet, launching him slightly into the air and damaging anyone caught in the blast radius
Aerial Triangle neutral Triangle - (Same as ground) side Triangle - (Same as ground) up Triangle - (Same as ground) down Triangle - (Same as ground; slow moving rocket)
Ground Circle neutral Circle - Return to Sender - Uses this vigor to create a small shield that will absorb 15 AP of projectiles, then sends it back as a quick projectile dealing a base 15 AP plus the amount of AP it absorbed side Circle - Undertow - Shoots a blast of water than pushes the enemy away; hold the button to charge Undertow to pull an enemy to you up Circle - Bucking Bronco - Shoots this vigor forward, sending the first enemy it touches into the air and has them float for a short amount of time down Circle - Shock Jockey - Shoots this vigor at the ground a few feet in front of him; turns into a trap if it hits the ground which lasts 3 seconds
Aerial Circle neutral Circle - (Same as ground; does not go through absorption initial phase) side Circle - (Same as ground; no charge applicable) up Circle - (Same as ground) down Circle - (Same as ground)
Super: Level 1 - Devil's Kiss - Throws a ball of fire a few feet in front of him, killing anyone caught in the explosion Super: Level 2 - Crank Gun - Pulls out a Crank Gun and fires from the ground to above him very quickly; has very long range; cranking process in initial activation animation Super: Level 3 - Songbird - Elizabeth arrives to aid Booker by opening a Tear into an alternate dimension. Elizabeth then calls Songbird to attack the enemies. Songbird appears in the background of the stage and uses smart AI to perform different attacks against the enemies: Songbird can perform a quick claw strike; Songbird can go high into the air and come crashing down on the stage; Songbird can fly across the stage at high and low altitudes at a decent speed. During this super, Elizabeth follows Booker and he can have her open up small tears in front of them that last a few seconds to slow down anyone caught in them.
