G1 Purist
A G1 purist is someone who acts like the world ended when the original series stopped. They're loud and refuse to accept any new transformers.
'I still use my old toy. It's better than your fancy new ones.'
'You don't know what you're talking about. You're not even a real fan.'
'I don't care if it's popular. It's not G1, so it's wrong.'
