Link's Advantages
* Squirtles light weight makes him very easy to KO.
* Projectiles and Zair can interfer with his aerial game.
Squirtle's Advantages
* Very quick and can close the distance between himself and Link very quickly.
* Amazing aerial game which gives him incredible combo potential in the air.
* Hydro Grabbing can be used to grab or to appraoch into Jabs or Dtilt.
* His RJCUsmash is very similar to a DAC, but it can KO pretty early.
* Squirtle's Water Gun can be used just like Mario's FLUDD. Link is very easy to gimp with this.
This match-up is going to be tough. Squirtle is fast, has fantastic combo potential, and is a very real threat offstage. Link has little chance here in this match-up. He's heavy, slow on the ground, and his projectiles are easy to get through with speed like Squirtles. Onstage you should focus on trying to predict his aerial approachs and stopping them with a Gale Boomerang or Zair. Double Draw has no real use in this match up due to Squirtle's size and speed. He could easily be infront of you by the second arrow. Try not to use this. Bair>Arrow Cancel is always a decent option to stop Squirtles from approaching you. Squirtle is very good offstage with the ability to throw multiple Fairs at you offstage which will gimp you. Squirtle also has Water Gun, a lesser version of Mario's FLUDD, but can be used in very similar ways and lets face it, it doesn't have to be that great to be able to gimp Link. Link's only real advantage in this match-up is that Squirtle dies very early to our KO moves like Dsmash, Dair, Fsmash, Ftilt, and Utilt.
