With her freedom, she and her sisters teamed up to take down HIM, once and for all. HIM caused chaos in Townsville, an unwilling Bliss as his weapon, and as The Powerpuff Girls opposed HIM, Bliss managed to break free of HIM.

Hypnotizing Bliss, HIM fused with her and absorbed her powers, and then unleashed an attack on The City of Townsville. However, it was soon revealed that 'MIH' was really HIM. Bliss was on the fence about this, torn between the love of her longtime friend, suspicion of the Professor's motivations and growing companionship between her sisters.

Bliss talked with MIH about her inability to overcome this issue with her powers, and MIH worked to try and convince her that The Professor and the girls hated her, saying that she should team up with him instead. However, Bliss had developed anxiety due to the erratic nature of her powers and how destructive they could be, and this anxiety came into play, causing her to once again cause destruction around her whenever she felt very nervous and upset. They tried teaching her about fighting crime, using superpowers, and having fun. After getting their heads around this, The Powerpuff Girls were ecstatic to have an older sister and they introduced her to their lives.

When Bliss turned out to be true, she and Professor Utonium explained her backstory and her reasons for coming back. This went on for a while until Bliss overcame her shyness, when it meant saving The Powerpuff Girls from Earth Plow. Bliss would repeatedly cause the same destruction as before, only this time, her disappearances would place the blame on Bubbles. When she told Blossom and Buttercup about Bliss, they assumed Bubbles was just making up another imaginary friend. Her first companion was the now existing Bubbles, who knew nothing of her backstory and just saw her as a basic friend to hang out with. By the time she'd become a teenager, Bliss decided to return to Townsville to see the Professor once again, events that would take place in the episode ' Power of Four'.īliss was nervous on her road back to her home, thinking more of the destruction she left behind than the potential joy she wished to bring. As she grew older, she'd become consistently reminded of her homesickness. There, she lived out at least 8 years of her life, not needing to worry about her uncontrolled powers, since the only other people around were animals, including a tiny elephant named MIH, who befriended her and stuck with her for the majority of her time on that island. When Bliss ran away, she'd discovered a deserted island called ' Bird Poop Island'. When he did, he decided to shelter them from any information about their previous sister, and let them enjoy the fact that they were perfectly functional creations, just like he always wanted them to be. As devastated as he was at the loss, he eventually decided that he needed to move forward from the past, and try again with making another perfect little girl. Professor Utonium thought she had died in the explosion. Shocked and ashamed at what she had done, Bliss fled to space, never to be seen by humanity forever, going to a deserted island where she'd spend her days trying to control her erratic powers. Growing increasingly upset, her powers merged with her emotions once more and an intense explosion destroyed the entire house. Soon enough it came to pass when Bliss grew upset about being unable to eat cereal without milk. This continued for some time, with the Professor and Bliss fearing the worst would come. Bliss would blast holes in the walls of the house and endanger the well-being of the Professor and everyone else around her. Professor Utonium started to realize that whenever Bliss got excited, enraged, terrified, upset, or basically any feeling, her feelings would mix with her powers, and would cause destruction. Professor Utonium loved Bliss and raised her the same way he'd raised his three future girls, but it was only a matter of time before Bliss' powers started coming into play and proving their danger. Thus, 'The Perfect Little Girl' was born, which he named ' Blisstina Francesca Francia Mariam Alicia Utonium', or ' Bliss' for short. He added sugar, spice, and everything nice into his concoction, but accidentally added in Chemical W, giving his creation superpowers. Bliss's creation happened when Professor Utonium got into a science-off with a rival scientist, Professor Newtronium, who had just created the Perfect Little Boy solely out of artificial ingredients and can fly so Utonium attempted to do the same thing, with the only difference being the gender and to fly further. She is about 8 years older than the girls, making her about 14. The birth of Bliss was years before the creation of Blossom, Bubbles, and Buttercup.
