Roy did less damage overall, despite having effectively lower reach for his "sweet spot" and a slower speed than Marth. While Marth's attacks do more damage when the tip of his sword connects, Roy's do more if the base of his sword connects. In Melee, Roy was a weaker version of Marth. Roy is back after taking a break from Brawl, and now he finally has a reason to exist. The stream can be aimed left or right with the control stick. Final Smash – PK Starstorm: A stream of meteors comes pouring from the heavens in a straight line.Lucas holds his PSI Magnet in front of himself, so it only protects him from the front, but it damages enemies inside of it when you let go of the button. Down Special – PSI Magnet: Create an energy field that absorbs energy projectiles.If it hits Lucas, he'll go flying in the opposite direction like a missile. This means Lucas won't start moving again until the thunder runs out or hits a solid surface, but it also means it can hit enemies multiple times. Up Special – PK Thunder: Similar to Ness' up special, except easier to control and it doesn't disappear when it hits an enemy.Side Special – PK Fire: Similar to Ness' version, but instead of leaving a column of flames for a moment, the flame flashes forward a bit, sending enemies flying farther.Works similarly to Ness' PK Flash, but it doesn't go as high. Standard Special – PK Freeze: Create an icy projectile that charges and floats as you hold the button and explodes when you let go.His side smash doesn't send enemies as far as you might expect it to, compared to Ness', but his up smash has the highest launch power of any up smash in the entire game, and does heavy damage to boot. His aerial attacks all focus on psi power and do decent damage. He doesn't jump as high as Ness, but he can still get a good bit of height thanks to his psychokinetic powers. Lucas' specials appear as alternates for Ness, but his real appeal is his reliance on psi attacks for tilts and smashes. Lucas returns from Brawl with few changes. Send out a ball of energy that stuns enemies before causing their heads to explode. Unlike other Mega Evolution Final Smashes, this is an attack instead of a proper evolution that you can control freely. Final Smash – Psystrike: Evolve into Mega Mewtwo Y.Doesn't work if your opponent isn't facing you. Stuns them for longer if they have higher damage. Down Special – Disable: Stun an enemy as though their shield has been broken.This move does no damage but Mewtwo is invincible as he's teleporting. Choose your direction with the control stick. Up Special – Teleport: Disappear and reappear somewhere else.Side Special – Confusion: Trips enemies up or send projectiles flying back to their source.Press the button to start charging it, and press it again to fire it. Standard Special – Shadow Ball: A standard charged projectile.He's no slouch on the ground, either, with his powerful down smash and dash attack. His neutral aerial surrounds him with psychic energy and can hit multiple times. His forward and back aerials pack a punch and his down aerial is an effective meteor smash. His forward throw doesn't do much damage or send enemies very far, but it involves firing a flurry of projectiles that can damage other opponents that are not caught in the grab. Mewtwo's upward smash attack draws enemies in and damages them multiple times before blasting them away. His aerial evade causes him to disappear for a moment. His jumps get decent reach, thanks to his floatiness. He is very light and easy to KO at low levels of damage. Mewtwo was missing from Brawl but he's back now as DLC. These characters can use equipment, but do not have custom special moves. DLC fighters can be fought against online, even if you don't own them. Kirby can eat them up and steal their neutral specials. Their icons can be used in profile cards. DLC characters also get added to All-Star mode as opponents, actually making that mode a little bit harder.
DLC characters have their own trophies as rewards for clearing Classic and All-Star, as well as background images for the ending credits. Fighters cost $4 for one version or $5 for both. Cosmetic items for Mii Fighters vary in price, and are available in bundles.
All DLC can be bought for a single platform, or in a bundle for both platforms at a greatly reduced price.
Starting in April 2015, Nintendo has begun releasing DLC for both versions of Super Smash Bros. for Nintendo 3DS Guide > Characters > DLC Characters
