So like did somebody order Miragex Noah symbiote au (transformers symbiotes au )
Mirages ego's so big that he's the only symbiote that can project hallucinations of his full form to it's host. That results into Noah interacting with nothing, not just talking to himself like Eddie Brock.
I loved Transformers: Rise of the Beasts and yes I do think that the 10 minute make out scene between mirage and noah was necessary it really furthered their character development, you know.
