@A2ZOMG: just for the sake of asking, why Ike?
Ike like Zelda is a character that really can do nothing to you if you know what to watch out for. Four out of his five aerials are powershieldable on reaction (and they can never be used to approach because they all suck on normal block anyway), and his "safest" attack, Jab, can be shieldgrabbed consistently at any range (as long as he touches your shield with Jab, and you time it right, and if you're not a tether, you can shieldgrab him out of Jabs even if your grab range is complete crap since he leans in on his Jab).
Ike is also the ONLY character in Brawl (a game where virtually every character is very floaty) who is unable to do two aerials in a fulljump. What this means consequently is that he's the worst juggler in the game and the worst edgeguarder, and generally he's really not able to followup on you at all. His horrible speed on everything makes his Jab cancel game nothing special, since it doesn't lead into anything that will ever kill you, and other characters outdo him in damage dealing most of the time because they actually have reliable options for juggling or following up, or they can camp in some cases. Did I mention that Ike is also the worst character in the game at getting back to the ground? You U-throw him and it's basically free damage (often a regrab) every time. Projectile camping also severely cripples this character.
He's a horrible limited character that has next to no depth. He's only better than Zelda because his recovery is less punishable/gimpable, he's heavier, and because Zelda somehow is actually worse at approaching than Ike (and has a bad shieldgrab).
He's better than Ganondorf because he can at least Jab if his opponent spotdodges, while Ganon can do nothing if his opponent spotdodges on reaction, and of course Ganon's recovery is crap and he's a bunch of fail on shields since his grabs are all easily spotdodged and because everything else sucks on block. If Ganondorf however was able to do something to people who spotdodge, he would be better than both Zelda and Ike, since aside from just failing completely at having any real response to spotdodges, his onstage tools are better and have existent and powerful followups.
At any rate Captain Falcon and Link are both clearly better than the above three mentioned characters. Captain Falcon is a character that can *gasp* approach safely on defenses with well spaced N-airs and B-airs, and sometimes D-airs. His Jab cancel game does similar damage to Ike's, except he has a MUCH better chance of being able to followup into a juggle/edgeguard due to his superior attack speed and mobility, which can and will eventually kill his opponent, albeit at rather high percents. Captain Falcon also has kill moves that are
safe on block. U-tilt, D-smash, and B-air. His Up-B out of shield is also a great punish option that does a lot of damage.
Link out of the mentioned characters actually has decently respectable camping and good spacing options. His projectiles are good tools for controlling space and punishing and setting up into other moves for some more damage, and his Z-air is gdlk for zoning. He has a number of ATs that give him much better mobility and punish options than his base attributes would suggest, and while mostly an unsafe move, his D-air is at least a worthwhile ledgetrap option. This character while still horribly gimpable in several situations, with good DI he can survive much longer than the other mentioned characters due to his good momentum cancel.
