Rising Uppercut (ライジングアッパーカット, Rising Uppercut) is Little Mac's up special move. In Super Smash Bros. 4, it is one of the more powerful up specials in the game and serves as Little Mac's primary means of vertical recovery, but has been cited to be the worst recovery move in the game, if not the entire Smash series.
Rising Uppercut is an attack similar to Corkscrew, causing Little Mac to spin as he ascends, finishing with an uppercut punch. The attack creates a stream of successive hits and ends with a strong upward blow. While the move deals less damage than most of his moveset (10% if all hits connect), the final hit is capable of KOing middleweights at 115% or earlier, due to its high knockback scaling.
The grounded version has a few frames of intangibility at the start, allowing Little Mac to potentially escape or interrupt multi-hitting attacks if an enemy is close enough (such as Fox's jab infinite). The aerial version sends Little Mac a shorter distance upwards but keeps its high knockback, making it Little Mac's only dependable aerial KO move alongside Jolt Haymaker. Little Mac can move left or right during the ascent, with the grounded version giving much more control.
This is Little Mac's only means of vertical recovery, but it is very poor at doing so in comparison to other up special moves due to its numerous flaws. The aerial version lacks horizontal momentum and gives vertical distance that travels as low as an average jump, giving it some of the worst distance of any recovery move in the series. Additionally, although its hitboxes are rather disjointed, the move does not edge sweet spot until the very end and has a small auto-sweetspot. As a result, recovering too high will result in Mac being knocked off by any sufficiently long hitbox, while recovering too low will often result in Mac missing the ledge entirely.
To maximize the move's recovery potential, the player should save Little Mac's second jump and attempt to end the move directly beside a ledge to prevent opponents from punishing the move's vulnerability.
Like most of Little Mac's special moves, Rising Uppercut has a unique 8-bit sound if he is using a Wireframe alternate costume.
In Ultimate, the move behaves in the exact same way, but the aerial version has been buffed to go slightly higher and Little Mac can grab ledges during the move, increasing its recovery potential. There is also a small amount of horizontal movement allowed as Little Mac nears the peak of the uppercut.
Special Move customization was added in Super Smash Bros. 4. These are the variations:
The uppercut is one of Little Mac's signature moves in Punch-Out!!. In Punch-Out!! for the NES, Little Mac visibly jumps off the ground when he performs any punches to the head, as he is too small to reach his opponents' heads otherwise. The spinning motion bears a strong resemblance to the 3-Star Uppercut from Punch-Out!! for the Wii, which is a more powerful variant of the uppercut. In Doc Louis's Punch-Out!!, Doc Louis spins in a similar way when he throws a single-star uppercut.
