Except not really? You have to completely break down Fox's and Wolf's specials to their utter basics to make them similar, just like I did with Link's and Samus'.
Not really. I mean, if you wanna break it down...
B:
Fox: Shoots gun straight forward. Can rapid-fire really quickly.
Wolf: Shoots gun straight forward, but with a delay. Cannot really rapid-fire, as he draws and holsters the gun for every shot, but it stuns, and he does apparently injure people standing right next to him even before the laser's fired.
Link: Shoots an arrow from his bow the moment the B button is depressed. The longer it's held, the farther it goes. Cannot save the charge. Arrow is affected by gravity.
Samus: Charge shot; starts charging on first B press, won't shoot until second B press. The longer the time between presses, the stronger it is. Can save charge by rolling out of the stance. Shot is not affected by gravity.
Side-B:
Fox: Holds still for a second, then dashes to another point on the ground in front of him in the blink of an eye. Anything in-between takes damage.
Wolf: Holds still for a second, then dashes to another point in front of him, a fair bit above the ground, in the blink of an eye. If he stops directly on an airborne opponent, they're spiked.
Link: Throws out a boomerang. Goes forward a bit (with some vertical angling if desired), then comes back.
Brawl and
Smash 4 made this the Gale Boomerang, so opponents get dragged toward Link when the Boomerang makes its return swing.
Samus: Fires a missile. There's also a Super Missile mechanic for Smash-B, although I've never had much luck with it. One of the two homes (I believe standard missiles?).
Up-B:
Fox: Charges for a second, then dashes headfirst in one of any eight directions held in a fireball.
Wolf: The same, but without the fireball, with a shorter charge time, and footfirst in a kicking animation. I think it drags opponents inward, too?
Link: Spin attack; the axis of spin is perpendicular to the ground. Can be done entirely on the ground (and can be charged if it is; no in midair, though), and tends to push opponents away.
Samus: Screw Attack; the axis of spin is perpendicular to the screen. Cannot be done entirely on the ground (she'll jump upward regardless), and sucks opponents inward.
Down-B:
Fox: Reflector. Sends projectiles back to the sender. Also knocks overlapping opponents away.
Wolf: Reflector. Looks different, acts the same. Does knock projectiles back faster than Fox's.
Link: Pulls out a large bomb, which can be thrown around. Damages Link if it explodes by him.
Samus: Lays a small bomb, which cannot be picked up in any way, shape or form, but can apparently be used to jump with (not that I ever had any luck with it).
Seriously, I get you hate people constantly asserting Wolf is a direct clone of Fox, but your Link/Samus analogy is really not comparable. Fox and Wolf are closer to a case of Mario/Luigi than Link/Samus are.
(I kinda wish I had better visual references on-hand right now, though. It's a lot more apparent visually than it is when you write all the details out...)
