Pokémon world locations

The Area Zero Underdepths (Japanese: ゼロの大空洞 Great Zero Hollow) is an area located within the Great Crater of Paldea at the center of the Paldea region.

Geography

The Area Zero Underdepths is a large cavern, roughly 3,300 feet below the surface, located beneath Area Zero. It is only accessible via the elevator in the Zero Lab by using the Indigo Disk.

The Underdepths formed approximately two million years ago. It experienced numerous cave-ins in the past, likely due to erosion and tectonic activity, but has remained stable since the last major cave-in.

The Area Zero Underdepths consist of several large chambers connected by tunnels. It is filled with large Terastal crystals, similar to those found at the bottom of Area Zero. These crystals increase with depth until the deepest tunnel is made from solid crystal. Also near the bottom of the Underdepths is a subterranean lake. On an island in this lake is a large tree, seemingly covered in or made from crystal.

Several Pokémon species also inhabit the Underdepths along with Terapagos, primarily Rock- or Ground-type Pokémon.

Terapagos

Battling Stellar Form Terapagos

After Kieran has been defeated, he will attempt to Terastalize Terapagos, causing it to become uncontrollable. The player must battle it with no opportunity to change teams or heal from the end of the previous battle; losing this battle will revert the game back to before the player's battle against Kieran. It must be caught by the player upon its defeat, and is coded to never be Shiny. Additionally, this Terapagos is always coded to be male, despite it having a gender ratio of one male to one female.

In the battle against Stellar Form Terapagos, it has four times the usual amount of health (with a large health bar across the top of the screen in a similar fashion to Titan Pokémon and Starmobiles, which identifies it as Terapagos, the Hidden Treasure of Area Zero), and unlimited PP for all of its moves, but its Teraform Zero ability does not function. Similar to a Tera Raid Battle, it can put up a shield to become immune to many status moves and reduce the damage it takes from attacking moves, and the player will be unable to Terastallize their Pokémon until they charge the Tera Orb by hitting with a certain number of damaging moves, but only two attacks are required to charge it, instead of the three from standard Tera Raid Battles. Unlike Tera Raid Battles, there is no time limit and no cheering, and the player can switch Pokémon and use items from the Bag.

Terapagos will put up three shields over the course of the battle: one at the beginning, and the others immediately after the previous shield is broken. Each shield covers 27% of Terapagos's health bar, and if any attack deals enough damage to break the shield, all further damage from that attack (including from multi-strike moves) is prevented, similar to Pokémon Sword and Shield's Max Raid Battles. When a new shield is put up, Terapagos is cured of any status condition, all stat modifiers to any Pokémon are erased (but other field effects such as weather and Light Screen remain in place), and if any of the player's Pokémon have been Terastallized, they lose that status. The Tera Orb must be recharged before the player can Terastallize a Pokémon again.

• In the first phase of the battle, Terapagos is Normal type, and Carmine participates as a partner using her Sinistcha. If Sinistcha faints, the player must continue the remainder of the phase alone. If Sinistcha has not yet fainted when the shield breaks, Terapagos will use Zen Headbutt at that time, and Sinistcha will automatically faint as a result, regardless of any effects that would prevent the move from being used, or would reduce the amount of damage dealt.
• In the second phase, Terapagos changes to a Psychic type, and the player must face it alone.
• In the third phase, Terapagos changes to a Water type, and Kieran joins as a partner using his remaining five Pokémon. Terapagos will remain Water type after the final shield is broken.
