In the "Power of Four" segment "Blisstersweet Symphony", Blossom, Bubbles, Buttercup, and Bliss fused together with the power of sisterhood to take down HIM. A Japanese woman proclaimed in shock, "Look! The Powerpuff Girls have formed into one giant Powerpuff Girl!" This fusion was supposedly named "Brambles", as somewhat of a combination of the names of the main three. Brambles and HIM battled it out in an Anime-style war and did things, like using a sword with their signature colors to slice him. HIM was able to get a stranglehold on them, spelling the end of Brambles, but not until Blossom, Bubbles, Buttercup, and Bliss hugged each other and strongly expressed their powerful sisterly love to cause a giant power blast to take down HIM once and for all. After that, Brambles disbanded and The Powerpuff Girls went back to their daily lives, well after the celebration of their victory.
Powers & Abilities
Sisterly Love - Brambles' four manipulators can show their love for each other, which causes her to turn entirely pink and generate a giant field of energy, with a bunch of hearts floating around in it, which they can then use to laser blast people, and even cause a giant heart-shaped explosion, that resembles the pulsating hearts at the end of every episode of the 1998 series, and a few episodes of her own series.
Sword - Brambles can materialize a sword in her hand. The blade is composed of three different colored stripes, the signature colors of the three main girls. And the hilt is purple, representing Bliss.
Teleportation - Brambles can spontaneously disappear and then re-appear out on thin air in random places.
