rocket raccoon has many long range options. he has 3 stages of mobility that change automatically depending on the last weapon used
Light - RR is pretty speedy, has double jump and a wall jump. this stage is default and is switched to when Laser Pistol or Double Laser Pistols are used. these are quick shots forward and can be used in air and off of a walljump. air version shoots down-forward
Medium - RR loses wall jump and double jump when one of these weapons are out.
-gatling gun, can be steered up and down slightly while shooting
-silver spear-type gun, single shot. seems to do same damage on block or hit
-small cannon, shoots a pulsing ray forward or up-forward. travels slowly and has small hitstun on hit, but on block it creates a second projectile that hits around the opponent for a bit. can be used in air
Heavy - RR cannot jump or dash and walk speed is slower. these moves have higher start when they are first switched to because Groot tosses the weapon to RR in the animation
-bazooka, shoots about 3/4ths screen and makes a 2nd explosion on the landing.
-heat rocket, tracking rockets that swirl. good tracking
-remote missile, can be controlled after the shot but RR is vulnerable for this time. this attack can be steered to overhead the target.
other stuff, many of his normals have projectile properties. when he taunts he drinks coffee.
