[Can I get Aron before the second gym]

Ok so I'm having a hard time with the second gym so I was curious if I could get a Aron before the second gym to help and if so how can I get it? All of my team is level 25, said team is made up by a Noibat, Roselia, Braixen and a Bronzor (Probably gonna replace the Bronzor later)

[Can I get these Pokemon?]

I'll get straight to the point, like the title implies I wanna get a certain Pokémon for my team but idk how to or if I even can, the Pokémon in question are the gible line, the honedge line and the deino line. So if you know anything about these Pokémon it would be a great help!

No, I don't think that's the problem it keeps saying 'Script 'PokemonField" line 1637: NoMethodError occurred.

undefined method 'spriteset' for # <Scene_Intro:0xc206c98>' and this problem happened after I saved in front of a mandatory trainer
