One Persona that you may want to consider adding to your lineup in the earlier game of Persona 3 Reload is Matador. He's a Persona of the Strength Arcana, meaning you can bring him along when you're working on the Strength Social Link to get an extra Social Link point. Matador works best as a physical fighter and has some decent Physical Skills to back him up. His moderate Agility also makes him ideal for the beginning blocks of Tartarus. As you progress through your Persona 3 Reload playthrough, you can swap him out for stronger Personas. However, Matador can also be used in various fusions to make stronger Personas, so he's one you'll want to unlock as soon as possible.
