Waluigi (Super Smash Flash 2)

Waluigi is a newcomer unlockable character in Super Smash Flash 2. Waluigi was teased during the Day 3 livestream at Super Smash Con 2018, immediately after 's reveal. He, along with his entire appearance and moveset, was fully revealed as part of the Day 3 livestream at Super Smash Con 2019. His sprite design is based on his various appearances as an Assist Trophy in the  series.

Attributes
Waluigi is a very combo-heavy character with a lot of unorthodox moves to give him the edge in battle. One of his most noticeable traits is his long limbs, giving him longer hitboxes for many of his attacks. His main KO options include forward tilt, forward smash, up smash, forward aerial, up aerial,, forward throw, and Whirluigi. His up tilt and dash attack both lead into aerial follow-ups, most notably up air. His forward smash can reflect projectiles and his up smash is a very useful out-of-shield option. Waluigi also has decent throws, with up throw being his most damaging, back throw leading into aerial follow ups, down throw leading into tech situations, and forward throw being a KO throw.

Waluigi is very good at edgeguarding, with his stand out edgeguarding tools being his meteor smashes, namely his up aerial and down aerial. His up aerial is unique as it is the only one in the game that can be used to meteor smash opponents, and it has a decently sized hitbox that requires the opponent to be above Waluigi for the attack to land. His down aerial is a stall-then-fall that spikes on the first few frames of activation, but even the sour spot of the move is quite strong. Waluigi's neutral aerial has a big hitbox that lingers and is very useful for comboing and edgeguarding. His long-ranged back aerial has a sweetspot at the end of his feet and is also good for spacing, while his forward air possesses great vertical range and high knockback.

Waluigi's neutral special move, Waluigi Dice, is a strange projectile that can have a variety of effects such as a windbox for edgeguarding, a poison cloud for damage, an electricity effect that stuns briefly, a meteor smash effect that buries opponents on the ground, and a powerful finisher. His side special move, Purple Torpedo, is similar to 's Green Missile with the main difference being that Purple Torpedo homes in on nearby opponents, making it another useful edgeguarding tool and both horizontal and vertical recovery. His up special move, Whirluigi, provides decent vertical height and has a powerful sweetspot at the end of the move that can lead to early KOs if landed. His down special move,, is a good stage control tool that can throw opponents into Waluigi's attack range for follow-ups in addition to blocking projectiles.

However, Waluigi has several weaknesses. He has poor traction, similarly to Luigi, which can leave him vulnerable when overextending and requires him to constantly be dash cancelling in order counteract his slipperiness. He is very tall and thus very easy to shield poke and combo, with characters such as, Luigi, and being able to juggle him easily. While most characters with these problems are heavyweights, Waluigi is only a mid-weight fighter, which harms his survivability. Furthermore, his lack of any real disjoints hurts his range and gives trouble when fighting swordfighters like, , and. He also has no real answer to most of the game's zoners, seeing as his forward smash is not a reliable reflector due to its startup.

His special moves, while versatile, also carry their own problems. Waluigi Dice has a fair bit of startup and its effect is completely random, dealing minimal damage and hitstun when rolling a 1. Additionally, while his recovery options cover a considerable distance, none of them snap to the ledge, which can leave him vulnerable to attacks. Purple Torpedo in particular becomes ineffective for vertical recovery when no opponents are in range, and opponents edgeguarding him can even abuse the homing function by having it target them downward and further away from the stage. Whirluigi is also easily abuseable due to its weak sour spot throughout the rising portion of the move, leaving Waluigi vulnerable while helpless.
