Link has been redesigned to match his appearance in The Legend of Zelda: Breath of the Wild. He can now pick up arrows he's fired, and his bombs have been upgraded to remote bombs, so you can set them off when the timing is just right!
Plethora of projectiles and long reach with sword give him lots of zoning and spacing options
Disjointed hitboxes on most attacks give him high priority
High launch power on many attacks
Hylian Shield blocks most enemy projectiles when standing idle, crouching, and walking
Possesses two meteor smashes: down tilt and down aerial
Arrows from Hero's Bow can now be picked up as items, making them more versatile in use
Increased damage and knockback from double arrows
Boomerang can be thrown at several angles and can be used as a zoning tool as well as a combo tool
Bombs are excellent tools for stage control, combos, zoning, camping, and edge-guarding, and can also assist Link in recovering
Below average recovery, relies on bombs to effectively recover when at higher percentages
Bombs cannot be detonated when picked up by enemies, and the explosion can hurt Link if he is not careful
Considerable lag on most kill moves
High falling speed hinders recovery
Average run speed causes him to fall behind other characters
Changes from SSBWU/3DS
Link's appearance is based off his appearance in The Legend of Zelda: Breath of the Wild when wearing the Champion's Tunic, with his classic appearance being an alternate costume.
This means now Link is right-handed, instead of left-handed like his predecessors.
Overall more range on sword attacks
Link received a new jab combo.
When at 0%, he can fire a projectile beam from his sword when using his forward smash.
Up tilt now starts from behind and ends in front
Forward air's hits connect more reliably now.
Grabs and Throws
Link no longer uses the clawshot or hookshot for his grab; as such, he also no longer possesses a tether recovery.
All of Link's Special Moves have their appearance updated to reflect its appearance in Breath of the Wild.
Link can pick up arrows that miss their targets; the next time the bow is used, it will then fire two arrows instead of one. Picked up arrows can also be thrown as items.
Link's Bombs can be detonated remotely; he is only able to have one bomb on the stage at a time, rather than two.
The Gale Boomerang has been replaced with an ordinary Boomerang.
Link has a new Final Smash that replaces Triforce Slash, in which Link uses the Ancient Bow to fire an Ancient Arrow in front of him in a similar fashion to Light Arrow.
