Training
Glass Joe
O.K. now in the begining, smack him in the head as many times until he blocks, then go to his stomach until he blocks and then switch, keep on doing that until around :40 second, what he does is goes up and he will attempt a power move, right before he comes down smack'em in the stomach. If your lucky, you'll get a K.O., if not, he will get up on 1. keep hitting him until you get a star, then dodge one of his move and use the star(an uppercut) then he'll be down.
when ever someone gets up on one, an uppercut will knock him down. Now when he gets up, dodge his move and strike back, its called counter-punch.
do that till he's down and out!
Von Kaiser
Now he will move his head and punch, dodge and counter punch to his head, keep doing that till he falls. He'll get up on one and Von will duck to the left 2 times so hit him in the stomach to get a star. dodge his straight punch hit him once in the head and use the star. he wil fall and when he gets up, do the same thing and he's down for a TKO!
Piston Honda
When he moves his eyes he is about to punch, so dodge and hit him in the face.
He will try some swings and uppercuts, dodge them and strike back. at one point he will go up and try a power move, time it and when he comes down, hit him in the face, that will knock him down. if he gets up
on 1,keep on hitting him in the face or in the stomach to get a star. dodge a swing or uppercut, hit once and unleash the uppercut to get him down once more. If not just do the same thing, dodge and punch and if he does a power move time it and hit him. after he gets up again, just dodge and punch.
Don Flamingo
He will not hit you till you hit him so you should punch anywhere and then dodge quickly and punch him in the head left-right-left-right and on and on. Keep doing that till he is down(he will be stuned and stay stuned if you do this correctly).
when he gets up, he will strike quickly after he gets up dodge and do the same combination. if you followed right he should be down for a KO!
King Hippo
He has a great defense so he won't give you stars. he does 2 moves, straight punch and a power straight punch. you dodge all his straight punches, you stand up to his power punches. to do that is simple. King Hippo opens his mouth before a power punch, all you do is punch him in the mouth before he hits you. If you hold up, he keeps his mouth open a secend longer. after you punch him in the mouth, hit him in the belly. repeat this strategy until he is down. He won't get up, he will never get up, you'll see when you get him down.
Great Tiger
Watch his turban, the diamand shines before he punches you(straight punches)
DO NOT DODGE THEM!!!! BLOCK THEM BY PRESSING DOWN!!!!! Then you punch him in the face multiple times, if you dodge, you can only hit him once.
do this till around 1:00. Then he ducks down and will try to uppercut you, before he uppercuts, punch him in the stomach like Von Kaiser to get a star, but it depends on which side he is on. If on the left punch left. He switches sides after uppercuts so punch left-right-left, then dodge an uppercut, hit him once in the face and use the star, then repeat. he should be down from 1-2 uppercuts. When he gets up, punch 3 times in the stomach to get three stars. dodge, hit to the head, and then uppercut 3 times to get him down once more. keep getting stars from his stomach and dodge and punch and uppercut. He should be down for a TKO. If he tries his power move, press and hold down till he punches, after quickly let go and press and hold and repeat till he stops, he is stunned, punch to the face should knock him out.
Bald Bull
He will start of with twirly punches(thats what i like to call them when i was smaller and still do, he twirls his hands then does a straight punch) dodge and counter punch. he does this till  :22 seconds and does swings. he does 3 swings then after swings he does 1-multiple uppercuts, so dodge quickly after the last swings and after the first uppercut, i warn you, THEY ARE FAST!!! some times if you hit him on the first uppercut, he doesn't finish. instead he goes back to hooks. remember dodge and counter punch. the 3 swings and 1-multiple uppercut are Bald bulls combination, remember that. after about 2 combinations, you should have him down. when he gets up, he will either do straight punches or his combination, but usually his combination.  after every third swing, he will do uppercuts. always dodge right after his uppercut just in case. now after 1-2 combinations, he should be down. now Bald bull won't alway follow this combination. When he gets up  he will probably do 1-3 swings and then he will do his power move. Time it and right before he comes down to uppercut you, punch him in the somach and he should be out for the TKO  
Piston Honda 2
he wil start off with straight punches, when he blinks quickly dodge and punch him in the face 3 times, you will get 0-3 stars. then he will uppercut couple of times. then he will do some more straight punches(do the same thing) and then he will go back to uppercuts. at times he will do his power move, press down to block and quickly punch couple of times and block and get some more punches and repeat. then he will uppercut and repeat this strategy of his. He also has a new power move he ducks and moves 4 times and uppercuts, just dodge it. Don't forget to use uppercuts.
Soda Popinski
Soda Popinski does everything 2 times in a row. He dances before he punches. he starts off with 2 swings. then he will go to uppercuts, remember, watch his legs. he will do straight punches occasionaly. When he starts to tremble, he is about to do 3 straight punches in a row, so dodge one and hit, dodge and hit. If you don't TKO him the first round, in the second round he will start with uppercuts and in the third, his second uppercut will be faster so be ready for that. thats all my advice.
Bald Bull 2
He will start with his jabs until around  :23 seconds. Then he moves his hands up and down, punch him any where to get a star. he does the same combination as before, 3 swings and 1-5 uppercuts. just dodge and strike back. don't forget to use the stars cause now you can only uppercut him and hit him with the bull charge to get him down. if you dodge all his moves and strike back, you should get him down the first time. Just dodge and punch. also when he does the bull charge, you can only get him down when he does the new lower bull charge, just time it and you'll get him down. don't forget to use stars cause thats the only way to get him down with the exception of the lower bull charge. just try not to get hit cause he takes off a hefty amount. And remeber, He usually follows his combination.
Don Flamingo 2
He's alot harder now, he does straight punches and swings now. just dodge and strike him in the head. Then he will go back to his "HIT ME AND I"LL HIT BACK" rutine. so just do as before, but now he won't always hit back, so watch it. if you do everything correctly, he should be down before he starts his rutine.
Just dodge and punch and you should give him a TKO by round 2 if your good.
Now when you start, just get a rhythm and you'll beat him, thats the same with everybody get a rhythm and you'll beat'em.
Mr. Sandman
This guy is a copy of Bald Bull. You have to hit him like King Hippo, once in the face, the rest in the stomach. he starts with jabs, they are hard to dodge but try your best. then he does swings, dodge them and hit back. When he starts moving fast, he will do his dream punch. when he pauses move left 3 times and hit him in the face once and then go to the stomach. the only big problem with this guy is his jabs. just get into a rhythm and you'll be fine.
Super Macho Man
This guy isn't too hard. now this guy is like soda popinski, likes to do 2 or more in a row. just do the same thing you did with soda popinski, find a rhythm. When he trembles, and doesn't do anything for a bit, he will do a weaker version of the Macho Spin. just dodge and strike. When you knock him down he will do a strong Macho Spin, just time it and dodge, keep on dodging cause he can spin up to 14 times in a row, so find a rhythm and keep dodging and you'll be fine, after you get the hang of it, you should TKO him in the first or second round. After I faced him a couple of times, I got his Hollywood Tan and smacked him SILLY with it!!!!! DO THE SAME!!!
Mike Tyson/Mr. Dream
First Round-
         For the first 1:31, he will do uppercuts that will knock your A$.. ummm But down! try your best to dodge these uppercuts of madness. dodge and counter punch! Then after he will do jabs that are hard to dodge but try your best.

Second Round-
         He will do 8-10 jabs, dodge and connect in the stomach to get stars. He will now do uppercuts and jabs, just dodge and strike. Now his uppercuts will not knock you down from 1 hit. After 1:30 minutes he will blink his eyes, connect to get stars. and then he will do something like the piston punch, so block and hit. he will do 4 of them. then he will go back to swings.

Last round-
         His punches are now harder to guess, just dodge and connect.
Just try your best and i'll come up with a Step-by-step procedure
