A whole new slew of updated Face Graphics as seen below. Some characters went through complete overhauls while others got touched up a bit. 

A brand new character was added to the game. Their name starts as J-DI, but you can name them anything you want! 

Gameplay balances were also made. 

-Crow gets new passive "Poison Expert" and "Advantage" replacing Absorb Poison and Vaccine
Poison Expert will now make ALL poison moves and your basic attack apply poison of you have better luck
Advantage will make you take less damage from any foe with Ailments.

-Runi gets a new passive, "Equate Aura" replacing Absorb Psy

Kiyota has two new passives, Frenzy Plant and Critical Shield replacing Arrogance and Absorb Blood
