Super Smash Bros. Ultimate/Meta Knight

Overview
Meta Knight is a knight from the Kirby Series, who just so happens to have numerous ways to combo. Should you encounter a player who knows how to fully use Meta Knight... you're done for.

Strategies
Meta Knight has the most combos next to Ness and Lucas. He also has numerous ways to use his special attacks.

Drill Rush
To be honest, Drill Rush is probably the most overpowered of Meta Knight's moves (not counting his Final Smash). While using it, you can tilt the direction up or down for either a drill effect or a launch effect respectively. No matter what you do with this move, the enemy will be sent to Brazil from the sheer power of this move.

Fang Over Fang
As you can imagine, the name for this combo comes from Naruto, not that that's important. Anyways, start by using the side special and tilt up, side special going down (use this in midair), and then finish by hitting them with a neutral special, which will launch them if the first two attacks didn't already launch them.

Mach Tornado
A powerful move, with three different uses. One, if used on an enemy over the edge, it can launch the enemy downwards. Two, if used on a fighter with over 60% damage, then they will be launched extremely far. And three, crazily enough, it can be used to KO smaller fighters almost immediately at the start of the fight.

Dimensional Cape
This is a really good move for recovery and for attacking. If you use it to recover and you hold down the B button, not only will it send the person who sent you off the edge flying, but it also does lots of damage. Although Shuttle Loop is better for recovery, this attack is also good because it doubles as an attack.

Spam Combo
Another great combo, which utilizes Drill Rush to spam damage. First, start out with the Drill Rush part of Fang Over Fang. Next, follow up with Shuttle Loop, and then finish them with a down aerial attack followed by a Dimensional Cape once they are back on the ground. Considering that the down aerial is the fastest down aerial in the game, the finishing part of the combo is extremely fast, and will result in the other player being unable to stop you when you pull this off.
