Bottom

Bottom is the main villain of the movie Pretty Cure All Stars DX 2: Kibou no Hikari - Rainbow Jewel o Mamore!. He is an unknown darkness entity who is revived after 1000 years, seeking to destroy the world and plunge it into darkness by stealing the Miracle Rainbow Jewel. He has two forms; his astral spirit form and his large gigantic revived form.

Reviving the Fallen enemies
In the start of the movie, a purple jewel containing his spirit is plunged into the ocean near Fairy Park. As his spirit is unleashed, he revives enemies of the Pretty Cures and makes them his subordinates, aiming to steal the Miracle Rainbow Jewel.

Taking over the Fairy Park
After his revived subordinates fail to take the Miracle Rainbow Jewel due to Pretty Cure's appearances, he decides to take over. Bottom arrives at the Fairy Park and steals the clam shell with the Miracle Rainbow Jewel, turning the amusement park evil and splitting all the Cures up, laughing demonically on their success. Although it is successful at their capture on the jewel, the Cures decide to get the Miracle Rainbow Jewel back from him. Bottom orders his minions to stop them at all cost before the jewel achieves its full power.

Full Resurrection and Defeat
After Cure Blossom and Cure Marine fail to get the Miracle Rainbow Jewel back, Bottom finally devours it and achieves his goal, causing all the Cures to lose all of their powers. Now along with his minions, they all fuse together, and Bottom is now fully revived, now resembling a huge demon giant. He says to all of them that all hope is lost now he has the Rainbow Jewel, and everyone in the world will perish and die as his world of darkness will be revived. But due to Cure Blossom and Cure Marine's determination not to give up in battle and their hopes not crushed, they decide to fight against Bottom using Floral Power Fortissimo, but fail as Bottom is too strong. The fairies then realize that hope is not lost due to Cure Blossom and Cure Marine's determination, and with their Miracle Lights, they give all the Cures their powers once again, upgrading themselves into Cure Rainbow and unleashed their most powerful attack to Bottom, Pretty Cure Rainbow Jewel Solution. Bottom counters it with a powerful blast, but fails as Cure Rainbow's power and belief in the light of hope overpowers him. The attack defeats and destroys Bottom.

Relationships
His revived minions shared a relation with him as they were revived as part of Bottom's body and spirit.

Trivia

 * If considered canonical, Bottom is the most largest of all the villains ever appeared in Pretty Cure history. He is also the most powerful of all the villains in the Pretty Cure community since he can be a god-like entity like Infinity and can destroy the Earth when necessary.
 * His revived form is based on the Behemoth, a giant appearing in the Hebrew Legend.
