Mega Evolution

Mega Evolution is a transformation that only appears in certain final form Pokémon or some Pokémon that cannot evolve. Mega-Evolved Pokémon are identified by having "Mega" in front of their name and a drastic appearance change from their previous form. Mega Evolution can only be achieved if there is a strong bond between a Trainer and his or her Pokémon.

Summary

Every Pokémon that can undergo Mega Evolution has a corresponding Mega Stone that is named after it, except for Rayquaza, which instead needs to use the move Dragon Ascent to Mega Evolve. Two Pokémon have multiple different Mega Stones for their species, named X or Y after the Mega-Evolved form.

Limitations

Each Trainer may only Mega Evolve 1 Pokémon per battle. Mega Evolution is essentially a free action a Pokémon may make in addition to its normal move, but if a Pokémon does not use a move, it cannot Mega Evolve. Mega Evolution will occur before most actions except switching. A Mega-Evolved Pokémon will only revert back to its original state if it faints or the battle ends; if it is withdrawn, it will still be in its Mega Evolved state once switched back in. Status conditions such as paralysis, sleep and confusion cannot prevent Mega Evolution, even if they result in the Pokémon not being able to move that turn.

Mega Stones are not affected by most moves or Abilities. Moves that would take away the Mega Stone from a Pokémon, such as the moves Bestow, Covet, Fling, Thief, Trick and Switcheroo will fail, Knock Off will not remove the Mega Stone or gain additional power, while Abilities Magician, Pickpocket and Symbiosis will not activate. The moves Embargo and Magic Room, as well as Ability Klutz, will not prevent a Pokémon from using its respective Mega Stone to Mega Evolve.

Stat Changes

When Mega Evolution was first introduced, performing it would not alter the attacking order previously during the Mega Evolving turn, so a Pokémon with a lower Speed than their opponent would still go after them on the turn Mega Evolution occurred, even if their Mega Evolution changed their speed. The attacking order would be determined normally on every turn afterwards. The newer core series games Pokémon Sun and Moon has patched this, such that the attacking order during the Mega Evolving round will now also be decided by the Speed stats after Mega Evolution, and this fix is eventually carried to Pokémon Brick Bronze in Version 0.14 update on 23rd June, 2017.

All other stat changes and type changes of a Mega Evolution will take effect immediately and damage calculation will proceed as usual — a Pokémon whose Mega Evolution possesses a lower Defense stat will take greater damage from Physical attacks on the turn of Mega Evolving. Changes in a Pokémon's Ability will also take place immediately.

Key Stone

This section contains spoilers!

To obtain the Key Stone, players must encounter the Eclipse Boss for a battle in Anthian Park. Before the battle begins, Rival Tess will give her Key Stone to the player in order to Mega Evolve the Absol that rushes in to help. Unlike in core series games, the Key Stone is not carved in a Mega Ring, Mega Bracelet or any unique accessories.

Mega Stones

Like in core series game Pokémon X and Y, where Mega Evolution was first introduced, Mega Stones can be found by various methods listed below.

On Field

One of the most classic and known methods of obtaining Mega Stones. There are Mega Stones scattered around Roria and players have to pick them up. These will appear as the regular Poké Ball on field, unlike core series games where they appeared as sparkles.

Event

Main article: Event Pokémon

Event exclusive Mega Stones are stones that have only been released once or are custom made for different custom colour Pokémon.

Given in Plot

Absolite is on the neck of Absol which automatically joins the player right before the boss battle in Anthian Park.

Purchase

35 kinds of Mega Stones can be bought, with 26 sold at the Stone Shop in Anthian City - Shopping District, 1 sold at the Golden Poké Ball Arcade in Anthian City - Housing District, and another 8 available at the BP Shop in the Colosseum Marketplace.

Hobo's Lucky Lotto

A number of Mega Stones can be awarded as the Day 3 prizes at Hobo's Lucky Lotto in Anthian City - Shopping District. Note that if the player hits 4 digits, it is a coin flip whether he or she gets Latiosite or Latiasite. The same goes for jackpot prizes Mewtwonite X and Y.

Primal Reversion

Primal Reversion is an ancient transformation of Pokémon. Pokémon that have undergone Primal Reversion are distinguished by the word "Primal" in front of their species name. It is similar to Mega Evolution, but instead of using the energy of people and Pokémon, the user instead absorbs the energy of nature to greatly increase its power. Primal Reversion is said to restore the true powers of a Pokémon.

In order to undergo Primal Reversion, a Pokémon only needs to be holding the appropriate Orb. Like Mega Stones, Orbs cannot be knocked off, thrown or stolen by any moves or abilities if held by the appropriate Pokémon. Unlike Mega Evolution, however, the player does not need a Key Stone or have to manually trigger Primal Reversion; it will simply happen automatically after the Pokémon enters battle and after any entry hazards take effect, but before the activation of weather-changing Abilities. Also unlike Mega Evolution, there is no limit to the number of times a Primal Reversion may be performed per battle.

Only 2 Pokémon are able to perform Primal Reversion: Kyogre and Groudon, members of the "Weather Trio". The final member of "Weather Trio" — Rayquaza, despite having its signature Orb as well, undergoes Mega Evolution instead, along with some other Legendary Pokémon.

Bond Phenomenon

Bond Phenomenon is a scarce transformation involving Battle Bond, which is an extremely unique Ability for a very special Greninja that allows it to bond and synchronize with its trainer. This Greninja can be bought in Anthian City - Shopping District, but it is sold for 150 Robux and cannot breed. Once this Greninja defeats an opposing Pokémon, Battle Bond will automatically activate and Greninja will immediately transform into a form known as "Ash-Greninja", which has its Speed, Physical and Special Attack stats significantly increased in a way that rivals Mega Evolution. This transformation is known as the Bond Phenomenon. In addition to the stat boosts, Greninja's signature move Water Shuriken will be powered up and always hit thrice.

Trivia

• A Pokémon that Mega Evolves will always obtain a base stat bonus of 100.
  • For Mega Alakazam, this only held true when comparing to its original form's base stat prior to Pokémon X and Y, otherwise the boost would only be 90.
  • Later on in Pokémon Sun and Moon, Mega Alakazam has been given a slight increase in its Special Defense stat, so that the base stat bonus evens out at 100.
  • However, Ash-Greninja gains a 110 base stat bonus instead when Battle Bond is activated.
• Latiasite, Latiosite and the 2 Mewtwonites are the only Mega Stones available in Pokémon Brick Bronze that were accessible before the Pokémon themselves appear in-game.
