I checked the d-base and it says that Galarian Slowbro's only ability is Quick Draw. This Galarian Slowbro is completely legit and I know bc I evolved it myself. Pls help.
Unfortunately, the Slowbro page on this site is incorrect, as Galarian Slowbro can have Own Tempo.
Hope this helps! :)
The DB has an error -- Galarian Slowbro can in fact have Own Tempo as an Ability.
Hope I helped!
