Bruno and Buttercup spent all the time together that they could. Bruno was even enrolled into Pokey Oaks with the girls. Bruno and Buttercup became pretty much the 'it' couple, if you could call it that, of the kindergarten. Everyone seemed happy for the two, except for two people, Mitch Mitchelson, who never seemed happy about anything, and one little blonde girl. This girl observed Bruno and Buttercup's happiness with each other, stalking them for weeks. She knew their worst enemies, which made her chuckle.
About a week later, a meeting took place around the candy shop. The Rowdyruff Boys were talking to the little blonde girl who didn't seem happy with Bruno and Buttercup. "So, what do you want out of our little deal?" The girl chuckled, "I want Bruno, you can have the girl, I just want him. And..." The girl stepped forward, revealing herself to be Princess Morbucks. "I always get what I want, and with daddy's money, I can get you boys anything you desire." The Boys laughed, along with Princess.
One day, during a normal run in with the Ganggreen Gang, a feminine cackle could be heard. After defeating the Ganggreeen Gang, they all turned to see the spoiled brat herself, Princess Morbucks. "What brings you here?" Morbucks smirked. "Him." She pointed to Bruno, who looked confused. "One day, you will be mine, and I even enlisted some help to make sure I never see you Powerpuff losers ever again!" Princess flew away cackling, leaving the 3 girls and Bruno to look at each other in confusion, wondering who the help was, but after a while Blossom shrugged and flew home, Bubbles behind her, and Buttercup and Bruno behind Bubbles. Little did they know that Princess's little encounter would begin Buttercup's and Bruno's fight for each other.
