>>40922256Pokemon you catch from max raid battles can gigantamax if they have the form, this is the only way to get a gigantamax pokemon right now because the game is not out we do not know if these gigantamax pokemon are shiny locked, seeing as this is gamefreak they likely are because gigantamax capable pokemon will be done the way certain pokemon are put out for raid battles in Pokemon GO
A Charmander that can Gigantamax is given to you after defeating Leon and no you cannot use it to breed more Gigantamax capable Charmanders your only hope for multiples is to win one in a max raid battle, as in you'll have to catch before the other characters or human players do.
It's gonna be a fucking mess, expect discord and community drama when teaming up with non human opponents to tackle a max raid Gamefreak puts out over the course of the game because as they showed us at E3 you effectively have to ask the other human players if you can be the one to capture this specific pokemon
On the bright side the ability to capture comes after fainting it in battle so no trolls can faint it as a fuck you to those who want it
Oh and don't expect PKhex to help you out this time, nintendo stepped up with their updates
