Neutral attack 1st hit - A small portion of the first claw swipe has an angle of 30. Unreliable due to having very weak knockback and low range.
Down smash - Spins in his shell on the ground. The first 6 hits are semi-spikes, though they cannot really be used as such because of the follow-up hits.
Back aerial - Thrusts himself backwards, attacking with the spikes on his shell. Has semi-spike properties, but its high ending lag combined with Bowser's poor vertical recovery make it a very risky edge-guarding maneuver. Less effectively semi-spikes in Brawl (its angle was changed to 35), though it became more powerful and less risky to use.
Up aerial - Does an aerial flip kick. The hitbox at his foot at the end of the animation semi-spikes opponents. Much less effective than in Smash 64; the semi-spike part of the move is rarely used in Melee and Brawl, as not only is it much weaker, but hitting with the main part of the attack doesn't produce vertical knockback like in Smash 64, but also sends opponents on a decent angle for edgeguarding, along with having more knockback than the semi-spike part of the move.
Down smash - Does a split kick. It is very fast with good power and decent reach. It can be very effective if landed near the edge. It has noticeable ending lag however, and its edgeguarding capabilities are rather limited. Less effective in Melee than it is in Smash 64.
Up aerial - Does an aerial flip kick. The hitbox at his foot at the end of the animation semi-spikes opponents. Compared to Captain Falcon's up aerial, it is stronger and produces more hitstun, and is overall more useful. It is one of the best and most known semi-spikes in both Melee and Brawl, and it complements Ganondorf's already deadly edgeguarding game.
Down smash - Does a spinning split kick. Low start-up lag and good power for a semi-spike. It has noticeable ending lag though, and with its very short reach, Jigglypuff is better off using its aerials and WoP for edgeguarding.
Down aerial - Does a drill kick. If it is sourspotted, the move can semi-spike. However, it is terrible for edgeguarding due to its extreme lack of power and its exceptionally small hitboxes.
Down smash - Does a spinning split kick. When sourspotted, it semi-spikes the opponent with decent knockback. To sourspot, Kirby has to hit the opponent with tips of his feet. It has decent reach and fast startup, so it is decent for edgeguarding.
Neutral attack 3rd hit - A very weak stab forward. Overall unuseful for edgeguarding.
Up throw - Slashes the opponent upwards. If it hits any bystanders, they will be semi-spiked.
Spin Attack (NTSC versions only) - Hitting someone with it after the initial hitbox semi-spikes the opponent. With very high base knockback, fast startup, and good reach, it is especially effective and is considered one of the best semi-spikes in Melee.
Down smash (sourspotted) - Swings two hammers on both sides. The sourspot is located at the handles. With fast speed and good reach, it isn't too hard to land, and has decent power.
Chef - The frying pan semi-spikes with low power. It is not effective as a edgeguarder due to its short reach and slow start-up lag.
Judge number 6 - Semi-spikes opponents with high base knockback, accompanied by flame damage. It is noticeable for being the only other Judge other than #9 that can be useful over other options. It is deadly to recovering opponents, but the random nature makes it difficult to land.
Down smash - It is the strongest semi-spike in Melee, and its high base knockback can allow for very early KOs near the ledge, being especially deadly against characters with poor recoveries.
Forward smash (tennis racket) - When sweetspotted, it has decent power for a semi-spike. Otherwise, it is weak. It is difficult to use for edgeguarding, due to its short reach and the random nature of Peach's forward smash.
Forward aerial - Quickly swipes her hand in front of her, semi-spiking the opponent. Extremely fast with good power, it is one of the most well-known and feared semi-spikes in Melee, despite its short reach and duration.
Down tilt - Sweeps his tail along the ground. Has set knockback. It is fast with decent reach, and can be useful for edgeguarding despite its set knockback.
Down smash - Does a tail smack in front of himself, then behind. Much more powerful in Melee than it is in Smash 64 and Brawl, along with sending opponents on an arguably more favourable angle. It also has extremely low startup lag. Can be used after an onstage forward aerial.
Porygon 2's attack launches opponents on a semi-spike trajectory with extreme power. It is by far the strongest semi-spike in Melee, KOing anybody with at least 25% damage.
Master Hand's open hand crush has two hitboxes; if the player is hit by his palm, they will be sent horizontally on a semi-spike trajectory with powerful knockback. If the player is just outside his palm, it instead results in considerable vertical knockback. Crazy Hand has a similar attack, though it is weaker and deals 10% less damage.
If the opponent is grabbed by the player and another opponent attacks the player that grabs the opponent, the opponent that was being grabbed will be sent horizontally on a semi-spike trajectory.
