I'll use his Special Moves.
Falcon Punch:
1. Regular
2. Less of a charge, and less power. (Think of it like Smash 64's Falcon Punch, but with less power)
3. A larger radius, but cannot be turned around (pivot).
4. A Falcon Punch that takes a larger charge, less damage, but can be cancelled out of.
Raptor Boost:
1. Regular
2. Falcon goes more of a distance, and slams his opponent into the ground.
3. Falcon goes slower, but does more damage than the regular version.
4. Falcon gets rid of the Raptor Boost and uses his gun that works like Wolf's Blaster, but faster.
Falcon Dive:
1. Regular
2. Falcon does his Shyrouken as shown in screenshots.
3. Falcon goes more of a vertical distance up, but cannot grab onto an opponent.
4. Falcon goes in more of an arc and goes faster.
Falcon Kick:
1. Regular
2. Falcon goes slower, but does more damage, similar to Ganondorf's Wizard's Foot.
3. Falcon goes faster and goes a farther distance, but does less damage.
4. Falcon goes at a great rate with a huge amount of damage, but also does recoil damage to himself. If it hits an aerial opponent, Falcon flies in the opposite direction.
