It All Ends Now III/The Final Showdown III or Go to Him, Bubble Balloon (Japanese: 最終超決戦IIIThe Final Battle III or 届け フーセンガムGo and Report, Bubblegum) is the 262nd round of the Pokémon Adventures manga.
Courtney tries to tell Ruby that his father, Norman, had arrived on top of Rayquaza. The collective roars of Groudon, Kyogre and Rayquaza drowns out Courtney's voice, which prevents Ruby from hearing her. Courtney tries to pull Ruby close and tell him, but a tentacle shoots out of the Cave of Origin and drags her inside. Ruby and Mumu go inside the shrine to try and save her. A three-way attack from Groudon, Kyogre, and Rayquaza causes a huge explosion, which breaks apart the Cave of Origin.
Ruby has Mumu try and move the debris, but Courtney tells Ruby to stop, as she can no longer move her legs. Courtney forces the Blue Orb out of her body and rolls it near Ruby. Courtney tells Ruby to face Kyogre and Groudon alone, as it's the end of the line for her. Ruby refuses and reveals that he wants to compete in a Pokémon Contest with her. When Courtney asks how he knew that she did Contests, Ruby remembers that when she burned a Ribbon back at Rusturf Tunnel, it couldn't possibly be his. Courtney flashes back to when she was younger and did Contests with Daisy Oak, which she guesses is why she has some affection for Ruby.
Courtney tries to tell Ruby about his father again, but the debris blocks her voice from reaching him. Instead, Courtney blows a bubble and covers it with Lansat and Starf Berry juice to increase the buoyancy and strength. She attaches her Memory Lighter to the bubble and sends it to Ruby. The battle between the three Pokémon causes more debris to fall, killing Courtney in the process, much to Ruby's horror.
Courtney's bubble balloon floats towards Ruby, who catches it. Ruby uses the light on a piece of paper, which comes out as an image of the Balance Badge. Ruby remembers Courtney's words, and notices that his father is standing on top of Rayquaza's head. As Courtney lies dying, she tells Ruby to bear witness to what she learned at the Mossdeep Space Center.
