I don't really have favorites, just Personas I really like because they were helpful to me in other MegaTen games. However, I do like the 4 Mitamas and the line of Angels (Justice, Principality, Power, Virtue, Dominion, Throne, Cherub, Angel).

Well aside from izanagi i like having jack frost on me at all times

Okuninushi and Alice are my favourite, the former due to Overclocked and the latter due to Persona 4, being my aces in their respective games. That being said, Sandalphon helped me through about half of the game my first playthroigh of P5, so I like him too. Strength Confidant OP.

Big Poppa Frost. That is all.

Looks wise Seth/Kohryu are so cool, I love giant dragons,

Alice and robin hood :3

Arsene is my fave looks wise, damage wisee I'd say satanael

Satanael and the four archangels (Uriel, Gabriel, Micheal, and Raphael).

It's hard for me to choose between Thanatos and Messiah. And their Picaro versions look even cooler!

Jack Frost.
