>>51058373According to Mr.Client himself (Eduardo Garza), they had to replace Gabo Ramos because the ones in charge of distributing the Anime didnt like at all that he was doing his voice work in Argentina so they asked the director to find a replacement living in Mexico asap and that's how Miguel Angel Leal got the role (he's even on the redub of the indigo league despite getting Misty and Brock's VAs).
Gabo returned in one episode anyways
