Pokémon Champions received a significant update on June 17, 2026, switching the game to Regulation M-B alongside the long-awaited mobile release. The headline addition: 11 new Mega Evolution forms, each with fully revealed abilities. Because these Pokémon originally debuted in Pokémon Legends: Z-A, a game with no Ability system, their abilities were hidden until now. That changes everything about how you build around them.
All New Mega Evolution abilities in Regulation M-B
The table below covers every new Mega Pokémon added in the Regulation M-B update, along with their abilities and what those abilities actually do in battle.
What are the brand-new abilities in Pokémon Champions?
Eelevate and Fire Mane are the two abilities introduced for the first time in Pokémon Champions, exclusive to Mega Eelektross and Mega Pyroar respectively.
Eelevate functions identically to the existing Levitate ability in terms of granting Ground-type immunity and hazard protection, but adds a snowball mechanic: knock out an opponent and your highest stat gets a free +1 boost. That extra clause makes Mega Eelektross genuinely threatening in a way that standard Levitate users are not.
Fire Mane deserves attention because of how it compares to Blaze, the ability it most closely resembles. Both deliver a 50% power boost to Fire-type moves, but Blaze only kicks in when the Pokémon drops below 1/3 of its maximum HP. Fire Mane has no such condition. The boost is always on. That consistency makes Mega Pyroar a more reliable attacker than any Blaze user, since you never have to engineer a low-HP situation to get full damage output.

Which abilities are worth building around?
Not every ability here is equally impactful. After running through the full list, a few stand out as the most team-defining.
Mega Eelektross (Eelevate) is the most unique pick in the set. Ground immunity plus hazard immunity is already excellent, and the knockout-triggered stat boost rewards aggressive play. This Pokémon can snowball a match if positioned correctly.
Mega Pyroar (Fire Mane) offers the most straightforward power ceiling. A permanent 50% Fire-type boost with no activation condition is the kind of consistency that makes team-building simple. You know exactly what you're getting every turn.
Mega Flainks (Defiant) punishes any opponent running Intimidate, Parting Shot, or moves that lower stats. Given how common Intimidate is in competitive play, Defiant becomes a strong deterrent that forces opponents to rethink their lead choices.
Mega Scrafty (Intimidate) brings the classic entry pressure that has defined competitive formats for years. Dropping opponent Attack on switch-in is reliable team support regardless of the meta.

How do abilities interact with existing Regulation M-A Pokémon?
The Regulation M-B additions sit alongside everything already available from Regulation M-A. If you want a full picture of the Mega Evolution roster and how to collect the stones needed to trigger these forms, the complete Mega Stones collection guide covers every stone, how to get each one, and how to spend VP without wasting points.
For players still getting comfortable with how Mega Evolution works mechanically, including which item tab the Mega Stones actually live in (it's not the main inventory), the Mega Stone equipping guide walks through the full process.
What else changed in the Regulation M-B update?
The June 17 update didn't only add Mega Evolutions. New base Pokémon and held items also entered the pool with this regulation shift, expanding team-building options beyond just the Mega forms listed here. For a breakdown of everything added to the roster, the full Pokémon Champions guide collection has dedicated coverage of the new additions.
The 11 new Mega forms give every team archetype something to work with, from hazard-immune sweepers to stat-punishing leads. Fire Mane and Eelevate are the two abilities that don't exist anywhere else in the game, and they're strong enough to anchor dedicated team builds.
