No, bowser junior doesn't have a brother. He does have a father: Bowser.
In a fight between Luigi and Bowser Jr, Luigi would most likely win.
Bowser, baby bowser, koopa, waluigi, wario, Donkey Kong.
no
Not likely because Bowser has a crush on Peach
THEY LOVE
Most likely not because he is preocupied by peach but who knows maybe Nintendo will suprise us.
Because Bowser loves Peach so much. But the guy dont know how 2 show love, unfortunally.
Love, obviously. True love... Even though Peach and Bowser must have slept together to have baby Bowser
Yes, he does. In the game Super Paper Mario, it shows that Bowser really does have feelings for her.
No! She helps Mario save Peach from bowser kidnapping her
Bowser is the Koopa King. In other words, he's a boy. This is best shown by the fact that he is in love with Peach, which is explicitly stated in Paper Mario.
As noted in Paper Mario, Bowser kidnaps Peach because he is in love with her. It may also be because he wants to take over her kingdom, which was why he kidnapped her in the first game, but it seems to be more about love than power.
