Meteor Smash Guide

Since you listed Bowser Jr. and Swordfighters linking hit meteors, you might wanna list them all. you also forgot a few regular ones. They are:

Corrin - Dair - linking hits meteor, as well as the final hit.
Diddy - Side B - not a linking one, but you forgot his Side B jump option meteors in the air
Cloud - Up B - same as Ike/Kirby
Ike - Neutral B - Tip of sword when fully charged and only on grounded opponents
Greninja - Down B - Holding down for the counter will make greninja spike the opponent
Pit/D.Pit - Uair - Linking hits
Fox - Dair + Fair - Linking hits
Jigglypuff - Dair - Linking hits
Meta Knight - Bair - Second hit
Pikachu - Fair - Linking hits
Sheik- Uair - Linking yada yada
Wario - Dair - You probably can guess
Yoshi - Dair - Ya, you can guess

Nice little guide. pretty thorough.
Though you forgot Luigi's down taunt.... (opponent has to be in very close to Luigi's foot as it brushes the ground)

Awesome guide! Taught me alot, although Samus had a spike with her up-tilt. It spikes at the heal a few frames after the start of the attack.

Great guide m8! thanks!

Very informative guide! You should add Bair for Lucas, it spike very hard ;)

This guide is informative. It helps me learn useful meteor smashes and those that have difficult sweetspots.

Awesome guide. Although Pac-Man has a spike if you hit someone in the air with his fire hydrant in the straight middle. Its really precise and I've only been able to pull it off a few times.

Wii Fit Trainer also has a spike on the back leg of fair, and another spike on the head hit of side-b (not entirely sure about sweetspot, might be something with the soccer ball). Link has a meteor on his dtilt, I believe on both the top and bottom edges of the sword.

Good guide. Captain Falcon's Side B spikes when you're above the opponent, and Up Tilt spikes at the heel throughout the entire move's animation.

Very nice guide! Captain Falcon's U-Tilt and Side B both meteor.

For Zamus, Down B spikes if the opponent is not grounded. If you don't press an attack button it will spike while the attack lasts. If you do the kick, it will spike on the first few frames of the kick. Great guide btw!

Very good Guide!!! Simple and straight to the point!

Very helpful but it doesn't include multi-hit moves that spike by not getting all the hits. For example, getting two hits of Meta Knight's or Yoshi's b-air.
