Description

Pokemon Ultra Sun Nexus is a hack of Pokémon Ultra Sun that reimagines Alola with Pokémon from all nine generations, including forms, Mega Evolutions, and paradoxes. It’s a more challenging adventure than the original, with tougher Totem Pokémon, trainers with full teams, and a level cap that dictates the pace of the story.

Features

Alola like never before

  • Pokémon from all nine generations, with regional forms, Mega Evolutions, and paradoxes.
  • 9th generation initials: Sprigatito, Fuecoco and Quaxly.

Wild Pokémon and SOS

  • Each area has up to 10 different wild Pokémon, all from the 6th to 9th generation (with regional forms and paradoxes).
  • All wild Pokémon can call for help (SOS). Each one can call up to 7 different allies, from Generations 1 through 5. This allows you to capture and train classic Pokémon without trading.
  • There is a 10% chance of encountering shiny Pokémon.

Tougher coaches

  • Regular trainers use Pokémon from the 6th to the 9th generation, and the difficulty increases progressively. It’s not extreme, but it is challenging.
  • Bosses and special trainers mostly carry teams of six Pokémon with items.
  • As a bonus, some trainers have shiny Pokémon . They appear occasionally, more frequently among bosses and special trainers.

Renewed Dominants (Totems)

  • The dominant Pokémon have new teams, with added Pokémon families, better attacks and items, and are more difficult to defeat. Their base stats have not been changed.
  • Each dominant Pokémon comes with a chosen ally to cover its weakness: if the dominant Pokémon is weak to a certain type, the ally covers that weakness. Plan your team carefully.
  • The caves in the trials have Pokémon from the same family as the dominant one.

Level Cap

  • Your maximum level increases as you progress. It also limits the Rare Candies you can get. The levels are 19 at the start, then 31, 34, 36, 47, 50, 69, and 74, after which the level is unlimited.

Mega Evolution

  • Mega Evolution is unlocked with the Activation Stone , which appears in shops after defeating the Fourth Dominant;  from then on you can use Mega Stones in the second half of the adventure.

Shops: Buy before you go

  • Each time you defeat a Dominant, the inventory of all shops changes, and the previous items disappear. Therefore, it’s advisable to buy everything you need before facing the next Dominant. All evolution items cost only 100 ₽.
  1. Before Dominant 1: evolution stones.
  2. After the Totem 1: Galar evolution items and classic items (King’s Rock, Metal Coat, Dragon Scale, Upgrade…).
  • After Dominant 4: Megastones and the Activation Stone.

Important information about the stores

Each time you defeat a Dominant (Totem), the inventory of all shops changes and the previous items disappear. Therefore, buy everything you need before facing the next Dominant (Totem).

  • All evolution items cost only 100 ₽.
  • Before the Dominant (Totem) 1: Evolution Stones.
  • After the Totem 1: Galar and classic evolution items (King’s Rock, Metal Coat, Dragon Scale, Upgrade, Magmatizer, Electrifier…).
  • After the Dominant (Totem) 4: Megastones and the Activation Stone.
