1 King Dedede

GOOMBAS VS. KOOPAS
4 Dark Bowser
Meet the dark king of Koopas!
Blastoise, known in Japan as Kamex, is a Pokémon species in Nintendo and Game Freak's Pokémon franchise.
Look at him! He's one of the strongest water type Pokémon ever! If Blastoise can fight Charizard, why not Bowser?
6 Donkey Kong
Donkey Kong is an arcade game released by Nintendo in 1981. It is an early example of the platform game genre, as the gameplay focuses on maneuvering the main character across a series of platforms while dodging and jumping over obstacles.
Wouldn't it be great if you saw this ape fight Bowser?
Sure that battle would be cool, but also unfair. DK can lift, THE MOON! Imagine what a punch from him would do. Then again, bumping into a bird takes out a third of his health, and Bowser can take several hits, so whoever hits first wins. Bowser is pretty slow, so I'm guessing DK takes it.
7 Wario & Waluigi
Hey, Bowser! Get ready to have your @$$ kicked by these guys.
8 Shadow Mario
You imagined Bowser fighting Dark Bowser before, but what about Bowser fighting Shadow Mario?
Link refers to several different incarnations of the same protagonist of Nintendo's The Legend of Zelda series.

Bowser is basically the king of Koopas, but what about his skeleton form, Dry Bowser? There's Dry Bones, which is a character that is a skeleton from Mario. I have a theory that Dry Bones is a skeleton of a dead Koopa Troopa. So, how does it still move? Kamek must have brought the Koopa's skeleton to life with his magical spells & that's how Dry Bones was born. Now that we've talked about my theory, we can conclude that Dry Bowser must be the Dry Bones version of Bowser. But hey, like Mr. MatPat says, that's just a theory, a GAME THEORY!
17 Baby Bowser
Remember in Yoshi's Island DS when Kamek kidnapped Bowser as a baby & Bowser blew fire at Baby Bowser? Bowser must be a child abuser. First, he abused himself as a baby in Yoshi's Island DS & now, he abused his son in Mario Party:Island Tour. Bowser, you sick ass! Wait until you get defeated by your self as a baby.

Getting owned by the youngest of your children is just the humiliation that Bowser deserves! - HeavyDonkeyKong
Samus Aran is the protagonist of the Metroid science fiction action-adventure game series by Nintendo.
It would be rather interesting to see certain series overlap like this, haha. Samus as the hero defeating the evil king Bowser would be pretty awesome. - Maplestrip
