Megami Ibunroku Persona
Both types and subtypes come in opposing pairs and have an effect on fusion. If the Spell Cards being fused belong to demons of the same type, the resulting Persona will have +5 to its highest stat and +20 to its magical defense. On the other hand, if their types oppose each other a fusion accident is more likely to occur.
A Persona's type and subtype determine which spells it can inherit via fusion. If the Persona is of the Light type, it won't be able to learn any Death spell and Dark Personas cannot learn any Expel spell. While the Element-Force pair by itself won't apply any kind of inheritance restriction, their subtypes will. For example, Sati is Light-Fire, meaning she can't inherit any Death or Ice spells. Jack Frost is Element-Ice so he can't learn Fire spells. Vidofnir is Element-Bless and thus has no restrictions.
In addition to influencing fusion, a Persona or demon's type and subtype may determine its strengths and weaknesses. They will possibly resist their type and be weak to its opposite. Furthermore, they may especially resist their subtype (draining, nullifying or repelling it) and be weak to its opposite.
For example, Ganesha is Element-Wind, meaning it resists Element and is weak to Force. Since he is of the Wind subtype, Ganesha especially resists Wind (in this case by repelling it) and is weak to Earth. The resistance to Earth from its type and weakness from its subtype cancel each other out so Ganesha takes neutral damage from Earth.
There are, however, demons and Personas who are exceptions to this rule. Some of those exceptions apply to entire Orders but others only to specific subjects. For example, the entire Grave Order is of the Force type, but they are weak to both Element and Force. And despite all of the Flight Order demons being Element-Wind, some of them resist Blast while others don't.
The PlayStation release uses all caps English names for the Types and Subtypes, which were left as-is in Revelations: Persona. The PSP port, however, uses Japanese names.
In Persona 2, a Persona's type restricts which skills it can learn from Skill Cards while a demon's type has no gameplay function and merely reflects their resistances and weaknesses. Despite being localized as "types", the Japanese version uses the same term as the "subtypes" from Megami Ibunroku Persona.
Localized as Element in DemiKids, a demon's type indicates their resistances and weaknesses.
Black/Red/White Book takes inspiration from the Chinese philosophical concept of Wuxing, which assign five elements as the foundation of everything in the universe and natural phenomena. Those elements are Fire (Agi), Earth (Magna), Metal (Zio), Water (Bufu), and Wood (Zan). The elemental affinities of the types are based on the "cycle of destruction" aspect of the doctrine. In addition to Wuxing, the game also has two additional types based on the concept of Yin and yang: Sun (Hama, buffs, and healing) and Moon (Mudo, debuffs, and ailments).
DemiKids changed the system for a more traditional elemental system like the ones used in most RPGs.
