Giratina's Altered Forme is a giant, draconic Pokémon, with an appearance similar to that of a large sauropod. It has 6 legs, gold protrusions that look like external ribs, and golden horns on its head. Its neck has five red stripes and 4 black stripes. On its back, it has a black stripe pattern that extends to its legs. It has black wings with three red thorn-like appendages called girasols (a rare type of opal) coming out of them. Giratina's Origin Forme is more serpentine than its Altered Forme, and resembles a draconic centapide rather than a dinosaur. Its wings are now shaped like tentacles with the red thorn-like appendages sticking out at the end. Its mouth is now behind the two appendages in front of its face. They open when Giratina roars or etc. The horns on its head are still the same. Giratina in Origin Forme has five rows of golden spikes protruding out of the torso and near the tail. Five gray and red stripes are partially overlapped by these spikes.

Dialga is a sauropod-like Pokémon. It is mainly blue with some gray, metallic portions, such as its chest plate, which has a diamond in the center. It also has various, light blue lines all over its body. It has a, somewhat, wing-like structure on its back, and a crest on its head, resembling a type of dinosaur. Dialga also has two horns on top of its head, two fang-like horns around its mouth, long claws, and a short tail, almost the impression of armor. Dialga was created when Arceus hatched from its egg and created the world. Arceus tasked Dialga, Palkia, and Giratina to create the universe—time, space, and anti-matter respectively. Dialga was worshiped as the master of time and metal, as it is a steel-type Pokémon. It is said that time flows whenever Dialga's heartbeat pulsates. When time disturb and it can devolve everything like reverse time.

Palkia is a very large, bipedal Water/Dragon Pokémon. The majority of its body has a light pink-gray-white coloring with linear sections on its body being purple. Its arms and shoulders are covered by large, armored plates, and each hand holds five nails. The round plates on its shoulders each have a large pearl in the center, representing its affiliation to Pearl. On Palkia's back are wings, which are seemingly not used for flight, as Palkia does Levitate. Palkia, along with Dialga and Giratina, was created by Arceus when it hatched from its egg. Palkia was tasked to make the universe along with Dialga and Giratina and create space.
