Bowser

Bowser-the king of the koopas. Ever since he was little, bowser has been mario's enemy. he has 7 kids and there's his other son-baby bowser aka bowser jr. Bowser has been kidnaping peach many times (approx:8 or so times ;)... ). Mario though has always comes to the rescued and has saved peach each time. so mario and bowser are big enemies. Even if they are big enemies, bowser has helped mario in both super mario RPG and mario and luigi superstar saga. Bowser has many baddies including koopas and goombas.
The games-

smb-the first appearence for bowser. he has captured peach and mario and luigi must save her. In the game, there are approximently 8 worlds and you find a castle at the end of each. In the back of the castle, youfill find bowser. to beat him, simply touch the axe to make him fall in the lava. bowser appeares in 8 bit.

smb3-In this game, bowser has captured peach and the 7 magical wands. In the 8 worlds of the game, you fill find each wand with a koopa kid. Jump on their heads to beat them. I have never seen final bowser, but...you probably be able to beat him.

Smw-In this game bowser has stolen peach and the 7 yoshi eggs. He once again has his 7 koopa kids protect the eggs. Bowser will be riding in the koopa car, so he is a little tricky to beat. Just throw mechakopas at him and you'll eventually win

SmRPG-In the beggening of the game, bowser captures peach, but when a giant sword falls into his castle, mario, peach and bowser get scattered around the mushroom kingdom. Eventually, bowser will team up with mario and other characters to beat smithy and save his castle

Smw2-When bowser was young, kamek, his caretaker, saw that one day 2 plumers would defeat the koopas, so he captured baby luigi. so yoshi teams up with baby mario and beats baby bowser.

Sm64-Bowser has captured peach and the power stars so mario has to save peach. You can fight bowser 3 times: The first is in the underworld. To beat him, grab his tail and throw him at a bomb. In lava sea, you do the same, but bowser has more tricks and is faster. In the Sky, You must throw bowser at 3 bombs. He is really fast and has a dangerous fire attack. well bowser will be beat again.........

Pm-bowser has stolen the star rod and captured the 7 star spirits. With the star rod, bowser can turn invincable. So, somehow......Bowsers castle gets under princess peaches castle and bowser captures peach..again. To make bowser turn uninvincable, the power of the star spirits heps.
too tired to finish, more later............................................................
