Semi-spikes, or pseudo-spikes, are attack in the Super Smash Bros. series and Super Smash Flash 2 that send opponents at a horizontal trajectory and then a vertical trajectory. In between the horizontal and vertical trajectories in the games, a quarter circle trajectory occurs before the vertical trajectory, which gives time to input a command. In Super Smash Flash 2, these moves send opponents in the same way.
Black Mage stabs his opponent with a knife behind him that gives excellent knockback. It is an excellent semi-spike but has low range.
Down Tilt
Black Mage sticks out a dagger in front of him on the ground. The move gives good knockback and is a good edge-guarding option against off-stage aerial opponents who are recovering.
Kirby crouches and quickly sticks out one of his legs forward. This move is a quick and powerful semi-spike.
Down Smash
Kirby spins around once on the ground with his feet sticking out to the sides of him. If the opponent touches his head or his underside, he or she will be sent upwards. If the opponent touches Kirby's feet, he or she will be semi-spiked.
Goku swings both of his arms downwards. This semi-spike must be sweetspotted at the fist. Has the appearance of a meteor smash, but it actually sends the opponent a semi-spike trajectory.
Sheik does a quick swipe infront of herself. It semi-spikes along with having high base knockback and high knockback scaling. This makes it useful for gimping opponents with poor recoveries and making it an excellent KO move at high percentages
