Earth Man may be able to copy abilities but I’d like to see him try and copy a Persona. Even if he can, Earth Man isn’t nearly smart enough to try and beat Akechi at his own game. Akechi gets a lot of props for being one of the craftiest characters in his verse and is not someone who should be underestimated at all here. Earth Man will quickly be overwhelmed and then obliterated. Goro Akechi wins.
