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.
Back aerialsweetspotted - Fox spins around and kicks behind him. One of the most powerful semi-spikes in Brawl, being capable of reliably KOing under 150%. Its edge-guarding capabilities are limited however, as its short reach and short hitbox duration makes it difficult to land. It additionally has high ending lag, giving it high risk to use offstage. If sourspotted, it instead hits at the Sakurai angle.
Reflector - Using the move to gimp is known as the shine spike. Unlike in Smash 64 and Melee, it has knockback scaling, though it's still extremely low and not noticeable until high percentages. Much more effective on characters with poor recoveries.
Forward tilt - Kicks straight forward. It is the second strongest semi-spike in Brawl at high percents due to its high knockback scaling, but its poor vertical reach limits its edgeguarding capabilities. However its power makes it effective at KOing near ledges.
Up aerial - Does a bicycle 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 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 edgeguard 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 Wall of Pain for edgeguarding.
Down aerial - Does a drill kick. If it is sourspotted, the move can semi-spike.
Puff Up - If an opponent hits it while it is shrinking, the attack is a OHKO semi-spike.
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 usable for edgeguarding.
Aerial Hammer (second swing) - A very powerful semi-spike, it is the second strongest semi-spike at low percentages and the third strongest at high percentages. However, landing it is very difficult since Kirby has to the land the second hit, not the first hit (which will knock the opponent out of reach for the second hit) and both strikes have noticeable start-up lag. If Kirby does land the second hit on a recovering opponent, it usually results in a KO. Both grounded Hammer and first hit of aerial hammer send the opponent flying diagonally instead.
Stone - Side hitboxes upon landing semi-spike with decent power. Very slow start-up and very limited reach make it near impractical for edge-guarding with, however.
Down tilt - Does a rapid kick towards the ground. Similar to Ness's down tilt, but is slightly stronger (cannot KO at 999%, however). It is near impratical for edgeguarding, as it has very short reach and produces no noticeable knockback at realistic percentages.
PSI Magnet - Releasing the move deals a semi-spike hit to nearby opponents, which can KO around 160%.
Down tilt - Thrusts his sword forward across the ground. Fast, good reach, and decent power makes this a effective edgeguarder, especially against those who try sweetspotting the edge. It is even faster in Brawl than in Melee, and does not need to be tipped, but its shorter reach and Brawl's physics make it less effective.
Down aerial - Thrusts his sword below himself. Extremely fast and low ending lag, Meta Knight can WoP opponents with his down aerial, making it deadly for characters with poor and/or predictable recoveries. This, combined with its decent power and Meta Knight's multiple jumps, make it arguably the best semi-spike in Brawl, if not the most versatile.
Aerial Shuttle Loop - Semi-spikes if the opponent is hit while Meta Knight is rising. Has very high base knockback but very low knockback scaling. Almost no start-up lag and very strong initial knockback makes it arguably the deadliest semi-spike in Brawl, as it is a near invariable KO if landed offstage or near the ledge. It's also great for stage spiking. Additionally, it's an excellent anti-edgeguard maneuver, as characters risk being semi-spiked away from the stage in attempting to edgeguard Meta Knight. It is a very effective edgeguarder, but is risky since it leaves Meta Knight in a helpless state after the move is finished. Most effective at edgeguarding opponents recovering from above, due to the nature of the attack and being less risky.
Forward tilt - Has a very disjointed hitbox and high knockback.
Down tilt - Opens a Manhole in front of himself. Has high base knockback, but very low knockback scaling. It is effective at edgeguarding, as it is fast, has good disjointed reach, and has a long-lasting hitbox.
Down smash (sourspotted) - Swings two hammers on both sides. The sourspot is located at the handles. With high speed, power, and reach, it is effective at edgeguarding. Even though its sweetspot sends opponents vertically, it can still be effective at edgeguarding given how powerful it is.
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 tilt - Does a rapid kick towards the ground. It is a semi-spike, but an extremely weak one. Nearly unnoticeable, the move is used mainly for racking up damage than to launch the opponent. Unable to KO even at 999%.
Dash attack - Pushes forward with PK sparkles in front of his hands. The hitboxes before the final hitbox send opponents on a weak horizontal angle.
Forward smash (tennis racket) - When sweetspotted, it is the strongest semi-spike in the game. Otherwise, it is weak. It is unreliable for edge-guarding, due to its short reach and the random nature of Peach's forward smash, but is potentially deadly.
Down smash - In Brawl, while it still semi-spikes, it was drastically weakened from Melee to the point where it can't even KO at Sudden Death percentages. Possesses stage spiking abilities however.
Dash attack - Fast and has good reach, but it is very weak and the semi-spike is only noticeable at very high percentages.
Down smash - The first strike is a semi-spike with high base knockback but the second strike is often landed afterward which has vertical knockback instead. At very low percentages, the much higher base knockback of the first strike can override the knockback of the second strike and results in a surprisingly powerful semi-spike, that may even KO depending on the location and character it was landed on.
Forward smash - A small amount of the first swing has an angle of 10 degrees.
Down aerial (landing) - Both the wind and the impact of landing are semi-spikes.
Down throw - A throw that semi-spikes opponents with surprisingly high knockback scaling for a throw. It can be very deadly if Wolf grabs the opponent on the edge as the throw has bizarre properties that negates the opponent's momentum, thus making it very difficult for some characters to recover.
Forward smash - First hit only, it is extremely weak and only noticeable at extreme percentages.
Blaster (melee portion only) - The melee hitbox of the blaster produces a weak semi-spike but the opponent is almost always hit with the projectile afterward, thus cancelling out the knockback of the first hit.
Reflector - Semi-spikes with extremely low set knockback. Despite 1 frame startup lag and intangibility, it's too weak to be effective against most characters in most situations. However, it can be especially effective at gimping characters with very poor or slow recoveries (most notably Falco).
Wolf Flash - The weaker hitbox can semi-spike opponents powerfully.
Hitting someone with a thrown Star Rod will result in a dangerously powerful semi-spike. This is complemented by the fact that it has downwards knockback.
Suicune's Aurora Beam is a semi-spike that OHKOs any opponent. When considering items, this is by far the most powerful semi-spike in Brawl.
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.
Several enemies in The Subspace Emissary have moves with these properties, and are usually extremely dangerous. Powerful ones include an Autolance's stab, the final hit of an Armight's combo, a Ticken's charge, and Tabuu's Movement Throw attack.
