Critical Hit
Critical Hit is the name of Marth's Final Smash in Super Smash Bros. Brawl. After Marth breaks open the Smash Ball, he charges up with power, and when the attack button is used, he swipes forward with his sword, hitting anyone with incredible force. He only hits once, unlike Ike, but anyone hit will be instantly knocked out, no matter what their percentage is, assuming there isn't an obstacle in the way. It could be considered one of the most useful Final Smashes in the game, assuming the player positions his/her opponents well. Interestingly, a Life Gauge appears when Marth uses Critical Hit.
The Final Smash's one hit KO is a tribute to the Fire Emblem games. The reason the attack does 60% damage is because that was generally the max HP any character in the Fire Emblem games could attain. The attack itself is also like the "critical attack" motion in Fire Emblem games. Finally, the two bars (which seems to be exactly 60)shown on Marth's opponents when he does his final smash represent the 2 HP bars from Fire Emblem games.
Super Smash Bros. Brawl Trophy Information
Marth's Final Smash. He thrusts his sword skyward, then rushes to meet his targeted enemy with furious speed. The blow he strikes is so powerful that his foe is instantly launched off the screen. As in Fire Emblem, a window appears that shows the character's hit points dropping rapidly to zero--but this is just for effect. Smash Bros. does not use a hit-point system.
