6. The first Persona the player can use all game is Makoto's starting Persona, Orpheus. Of course, as the first Persona the player gets for free, Orpheus is not the absolute best, with two nasty weaknesses to what?
From Quiz "Persona 3" - Makoto Yuki
Answer:
Electric and Dark
The Dark weakness is much more of a concern- if Makoto dies at any point, unlike the rest of the team, the player will receive an immediate Game Over. Dark skills are exclusively insta-kill, so if Makoto is targeted by one, he will likely die. Correcting this or, better yet, getting a different Persona ASAP would be a good idea.
