Lucario, number 448 in the National Dex and a Sinnoh Pokémon, holds Lucarionite Z to become Mega Lucario Z, taking its total from 525 to 625. The biggest single gain is 61 Speed, followed by 49 Sp. Atk. It also loses 10 Attack.
The typing does not change — it is Fighting and Steel before and after — so the Mega is the same defensive problem as the base form, only bigger. Mega Evolving replaces Steadfast, Inner Focus and Justified with Adaptability.
As Fighting and Steel, 3 of the eighteen attacking types get through for extra damage. It resists 8 and is outright immune to 1. The full board is above; the short version is that the types listed under ×2 and ×4 are the ones worth planning around.
Mega Lucario Z cannot be used in the current Pokémon Champions regulation, so there is no ladder data for it and no legal set to report. Lucario itself is legal and is played on 0.12% of teams — it is the Mega form that is barred, which means the Lucarionite Z is the part you cannot bring.
Regulation M-B closes on 9 September 2026, and legality is regenerated from the format data on every build rather than written by hand, so this page will change on its own if that changes.
Smogon publishes no head-to-head checks-and-counters data for doubles formats, so this list is computed, not measured: these are the most-played Regulation M-B Pokémon carrying a damaging move of a type Mega Lucario Z takes extra damage from.
Of the 91 Mega forms in the dex, Mega Lucario Z is 38th by base stat total. Its best stat is Sp. Atk at 164, which is 12th among Megas; its worst is Sp. Def at 70, 86th. One other Mega shares the Fighting and Steel typing and therefore this exact matchup board: Mega Lucario.
A Mega slot is a commitment: the stone occupies the held item, so whatever Mega Lucario Z would have wanted from an item, it does not get. Drop it into the team builder to see what the rest of the six then have to cover, or take it to the damage calculator to find out whether those 164 points of Special Attack actually change a knockout.
