When used, Captain Falcon pauses for a split second before dashing a short distance forwards. If he hits an enemy, he proceeds to unleash a fiery uppercut, which pops opponents up into the air with below-average knockback. If Captain Falcon does not hit a target during the dash, he falls down and is easily punished. In an even worse case, if he falls off an edge with this move in Melee and Brawl, he immediately becomes helpless and is very likely to self-destruct. In Smash 4 this no longer happens, as he will either stop at the edge or, if he was there already, dash off the edge, with the attack thereafter being treated as aerial.
During the dash, the move has an inert collision detection hitbox that cannot clank with opposing attacks and does not possess a damaging hitbox unless it connects, leading to the misconception that Raptor Boost has inherently low priority. For this reason, as well as its aforementioned endlag if it whiffs, this move sees much more use in tech-chasing than approaching, due to its duration and range. Additionally, it can be comboed directly into an up aerial or Captain Falcon's Knee Smash to achieve KOs.
When used in the air, the move changes from an uppercut to an overhand punch, acting as a meteor smash. Captain Falcon becomes helpless whether the move connects or not; as a result it is very risky to use in midair. In Melee, Captain Falcon's momentum instantly halts when he hits an opponent, making the move difficult to survive using in any case. In Brawl and Smash 4, however, he bounces over the meteor smashed opponent and keeps a bit of sideways momentum. In the latter game, an airborne Raptor Boost does not meteor smash unless the opponent is directly under Falcon, making it less reliable in the air.
In Melee, Raptor Boost was unable to grab ledges, making it somewhat poor for horizontal recovery. This issue was remedied in Brawl and Smash 4.
In Smash 4, Raptor Boost was significantly buffed in knockback, being the strongest iteration of the move to date. While still a decent combo starter at lower percents, it has been seen earning decisive KOs under 125% on the majority of the cast. To combat this new utility, it has more ending lag when it connects with an opponent or a shield.
Special Move customization was added in Super Smash Bros. 4. These are the variations:
