Super Smash Bros. Melee/Marth

Melee Items
It is worth noting that, when smashing with a melee item (i.e. beam sword), Marth and Roy swing their sword first, followed by an item swing. Against low-percentage enemies, the first strike is a great check and provides excellent positioning.

Disjointed Hit Box
Marth’s sword is a disjointed hit box. His sword is not part of his body, and if someone hits his sword you will receive no damage.

Grab Range
Marth has the best non-grapple grab range in the game, and the grab hitbox extends well beyond where his hands reach. When considering the usefulness of his throws in chainthrows and combos, Marth can be said to have the best grab game in the game.

Foward Air combos
Marth's Forward air comes out and and finishes extremely quickly, and it is possible to pull off another aerial after short hopping a forward air, provided one performs the forward air quickly enough after leaving the ground. This is a crucial aspect of many of Marth's combos. By far the most popular aerials to perform after a short-hopped forward air is either simply another forward air, or an up air to pop them up into the air for an up tilt or a grab.
