Guarding is an option available in the battle menu. If used, the user will not do anything, but during that turn they will have their defense increased against other attacks. In some games in the series, defending characters will be protected from being Downed against elemental weaknesses.
Shin Megami Tensei NINE
Reinforcements will guard if they have no healing or support moves available.
Devil Summoner: Soul Hackers
Defense Kuzushi and Defense Yaburi deal more damage to guarding targets.
Megami Ibunroku Persona
Both party members and enemies can guard. While there are enemies in later games capable of doing this, such as Shadow Yosuke from Persona 4, they are exceptions rather than the norm, and as such the first Persona remains the only entry in the series where all enemies and bosses are capable of guarding.
Persona 2: Eternal Punishment
The enemy-exclusive skill Guard Punish deals high Almighty damage to all party members and will ignore damage reduction from defending targets. Instead, it will do double damage to guarding targets.
Persona 3 Portable
Persona 5 / Royal
If the user guards, the damage they'll take will be subtracted by x0.4.
