Little Mac should have a secret taunt feature, where Doc Louis gives him advice on how to deal with his opponent.
In fact, I still have those old conversation concepts lying around.
Little Mac vs. Donkey Kong
Doc Louis: Hey Mac, didn't you fight this ape before? Anyway, Donkey Kong is a big powerhouse. He moves pretty fast for a heavyweight, and his hands pack a punch. But he's not a very fast attacker, so try to use that to your advantage. By the way, be sure to ask DK for his autograph when the fight is over, okay?
Little Mac vs. Rosalina
Doc Louis: Hey Mac baby, they say you shouldn't hit a woman, but I don't think you want to hold back on this one. Rosalina may not be powerful physically, but her magic is nothing to laugh at. If you get hit by her magic, it'll be lights out before you know it. She's also a long range attacker, so getting in close is the key. Good luck out there son, and please don't beat her up too badly.
Little Mac vs. Ganondorf
Doc Louis: Oh man, this guy is giving me the shivers back here. Mac, Ganondorf is not someone to take lightly. His power can mean game over in an instant, especially with that sword of his. Watch the sword, avoid it, and hit him good. You got it son, you got it.
Little Mac vs. Mr. Game & Watch
Doc Louis: Looks like you're up against an old classic there Mac. Mr. Game & Watch's attacks consist primarily of objects from the Game & Watch series. They may not look like much, but those objects can pack a punch. Evade them, and then give him a good punching, old school style baby. Man you sure came a long way since then Mac.
Little Mac vs. Wario
Doc Louis: Hey Mac baby, Wario is one gross competitor that you don't want to take lightly. He's got gas, and if he grabs you with his teeth, you'll be in for a biting. I must say though, I've heard that he loves to eat chocolates. Makes me want to eat a chocolate bar after this. *laughs*
Little Mac vs. Captain Falcon
Doc Louis: Hey Mac baby, you're up against old Captain Falcon, eh? He may have raw power and quick feet, but he's not a fast attacker. Take advantage of his slow attack speed whenever you have the opportunity. Got it?!
Little Mac vs. King K. Rool
Doc Louis: Boy oh boy, this guy must have one heck of a sore eye there. Makes me want to duck and cover. K. Rool is big, super heavy, and powerful, but he's also a very slow fighter. Get to him before he gets to you. After all, the bigger they are, the harder they'll get knocked out. *laughs*
Little Mac vs. Kirby
Doc Louis: You might want to be on your toes for this opponent Mac. Kirby may not look like a threat, but his ability to inhale his opponents is not something to underestimate. If he gets you, he'll copy your moves. In other words, don't get swallowed out there. Hmm, with an appetite like that, I wonder if he likes chocolate bars, because I can sure go for one right now.
Little Mac vs. Sonic
Doc Louis: Wow, Sonic sure is one fast character there. Therefore, you just have to be faster when facing him Mac. Beat Sonic to the punch, and you should do fine. Man, just talking about Sonic makes me rather hungry; maybe I'll get a chocolate bar to hold me over. *laughs*
Little Mac vs. Mewtwo
Doc Louis: Let's go son, Mewtwo is a brutal opponent, so you'll have to take it out before it gets you. Just watch out for its PSI abilities, give it a good beating, and you'll have this match in the bag. *laughs*
Little Mac vs. Mario
Doc Louis: Looks like you're up against old Mr. Nintendo himself there Mac. Anyway, Mario is a well balanced fighter without any major weaknesses. Therefore, you'll just have to get in there, and give him everything that you've got. Got it?!
Little Mac vs. Ike
Doc Louis: That sure is one big sword that Ike has there. If you're ever going to beat him Mac, you'll have to get past his powerful sword arm. Fortunately for you, he's not very fast, so take advantage of his weaknesses before he even gets a chance to fight back. Now, if only there's a chocolate bar that's as big as Ike's sword, cause I'd sure want to get a hold of that. *laughs*
