He could use some of those moves in Smash Bros in addition to attacks revolving around slashing.

As a fighting-type, Gallade can learn a wide array of punch-based attacks in the games such as the elemental punches, Drain Punch, Focus Punch, Power-Up Punch, etc (even some kick-based attacks like Low Kick).

He can read his opponent's mind and could use teleportation for certain movement.

As a psychic-type, Gallade is capable of using psychic powers.

Gallade can utilize blades of dark energy, leaf energy, psychic energy, etc.

Through attacks like Night Slash, Leaf Blade, Psycho Cut, etc.

Gallade can grow blades from his elbows.

Now let's look at what Gallade brings to the table as a swordsman.

Most convincing of all, none of the Smash swordsmen are capable of dual-wielding.

All of the current Smash swordsmen are very limited with the use of physical-based attacks.

None of them can use psychic powers (except for Shulk and his visions, though his visions are powers from a god, not from psychic ability).

None of them can change their blades to a different type for that matter (yes, there is Shulk and his Monado Arts, but in the end, the Monado remains an energy-based sword no matter what style you use it as).

None of the Smash Bros swordsmen are capable of growing swords from their elbows.

Gallade would be one of, if not the most unique swordsman in the Smash Bros roster. Combine all of this together and you see that Gallade is essentially a psychic knight.ДЄside from being a popular Pokemon in the games, evident with the fact he gained a Mega Evolution in the most recent Pokemon games, Gallade perfectly fits into Smash Bros just by looking at him. When necessary, Gallade can use his psychic powers to reshape his arms into blades and utilize a dual-wielding style. When he Mega Evolves, plates emerge on Gallade's arms, and his helmet and cape-like protrusions on his head and back gives him a more knightly appearance. Gallade is a master of courtesy and swordsmanship that is capable of sensing the opponent's thoughts. He is also known for his design, being a cross between a heroic knight (based off his actions and stances) and a gladiator (going off the helmet). He is also one of the two Fighting-types to have the highest special defense stat of all non-legendary Fighting-type Pokemon, and when Mega-Evolved, he has the highest attack stat of all non-legendary Psychic-type Pokemon.ДЄs his Pokedex entries state, Gallade is particularly known for using his elbows as sword blades when fighting against his foes.

Gallade has also gained a Mega Evolution in Pokemon OmegaRuby/AlphaSapphire, the most recently released main-series Pokemon games. He evolves from a male Kirlia when exposed to a Dawn Stone. He is part of the Ralts evolution line as one of its final evolved forms and is seen as the male counterpart to Gardevoir. His name comes from the combination of the words 'gallant' and 'blade'. Gallade is a dual-type Psychic/Fighting Pokemon that was introduced in the fourth generation of Pokemon.

Heartgold/Soulsilver/X/OmegaRuby Pokedex EntryвЂ‹ 'Because it can sense what its foe is thinking, its attacks burst out first, fast, and fierce.' 'When protecting someone, it extends its elbows as if they were swords and fights savagely.' Diamond/Pearl/Y/AlphaSapphire Pokedex entry 'A master of courtesy and swordsmanship, it fights using extending swords on its elbows.'
