Some of Luigi's skills:

Fireball: You know what this is.. Relatively ineffective though.

Super Jump Punch (Shoryuu-Ken): He attacks with an uppercut (punch directed to the sky) while in the air, with a super big fist.

Luigi Cyclone: The Luigi Cyclone is an all-purpose attack, because there is little recovery to this move. It attacks at all angles, and while performing this move, he is invulnerable. Basically, the Luigi Cyclone looks like Luigi spinning really, really
fast, causing a white-in-the-air effect.

Green Missle: Luigi makes his head point at the opponent, then, he'll launch himself at him/her. Sometimes when using the Green Missle, he'll be ignited, causing a big explosion; when this happens, he deals a LOT of damage.



Some of Fox McCloud's skills:

Laser: Fast attacking move, but causes minor damage. Doesn't phase opponents, but the farther away, the more damage inflicted.

Fire Fox: Fox becomes a fireball of sorts and sets ablaze those who touch him.

Fox Illusion: Fox dashes at light speed, causing him to be invincible while doing so. No damage gets inflicted, but is used to travel through enemies and get out of danger quickly.

Reflector: Bounces projectiles off him, shocking opponents on activation only.

Various Kicking Techniques: Such as rapid kicking, roundhouse, flip kick, tornado kick, spin kick, flying kick, and back kick. All do minimal damage, but are effective inside melee abilities to have.



Now, as I see it, Fox couldn't possibly lose. He not only has faster skill abilities than Luigi as a whole, he has major evading techniques and would never get in a situation he can't get out of. How can the minimal moves on Luigi's part actually cause enough damage to take down Fox?
