As fans eagerly await more updates on Kingdom Hearts 4, speculation about how Square Enix will bridge its various inspirations continues to grow. Historically, the Kingdom Hearts series has blended its original characters and worlds with those from Final Fantasy and Disney, but Kingdom Hearts 3 notably reduced the presence of Final Fantasy elements. This decision left some fans divided, with many longing for the franchise’s earlier balance. One way to strike this balance in Kingdom Hearts 4 could be the introduction of a Final Fantasy 7-inspired Materia system. This mechanic would subtly honor Final Fantasy without disrupting the narrative focus on Kingdom Hearts' universe.

The Materia system from Final Fantasy 7 Rebirth and its predecessor allows players to slot abilities into weapons and armor, offering a wealth of customization options for both combat and strategy. A similar system in Kingdom Hearts 4 could integrate seamlessly, enhancing gameplay while paying homage to one of Square Enix's most iconic franchises.

A Harry Potter world could make for a great deal of fun. Sora already has access to a range of powerful spells, so he would likely fit in at Hogwarts if he got the chance to go there in a future Kingdom Hearts game.

Kingdom Hearts 4 Could Adapt Materia’s Versatility

The Materia system excels in Final Fantasy 7 by giving players the freedom to experiment with spells, buffs, and even unique combinations like linking AP Up Materia with others to double experience gain. In Kingdom Hearts 4, a similar system could replace or complement the existing upgrade mechanics for Keyblades. Imagine Sora slotting Materia into his Keyblade to cast spells like Protect or Shell, reduce incoming damage, or even summon familiar Final Fantasy creatures like Ifrit or Shiva.

This mechanic would elevate combat without overshadowing Kingdom Hearts' identity. For example, pairing a Thunder Materia with a Stun Materia could create an electric shockwave that immobilizes multiple enemies. The system would also align well with Kingdom Hearts' emphasis on player choice, as Materia could allow for further customization of Sora’s moveset and strategy. Integrating Materia would also enrich exploration. Similar to how players gathered materials for Keyblade upgrades in Kingdom Hearts 3, Materia could be discovered in treasure chests, obtained as rewards for quests, or dropped by powerful enemies. This would incentivize players to explore every nook and cranny of Kingdom Hearts 4’s worlds, tying the mechanic into the game’s sense of adventure.

A Subtle Tribute to Final Fantasy Without Overshadowing

One common critique of the series' most recent entry was the minimal use of Final Fantasy characters in Kingdom Hearts 3. While this decision allowed the game to focus on its growing cast of original characters, it left a gap for fans who appreciated the crossover aspect of earlier titles. Incorporating the Materia system in Kingdom Hearts 4 would bring back the essence of Final Fantasy in a way that feels natural and unobtrusive.

The Materia mechanic wouldn’t require direct appearances from Final Fantasy characters like Cloud or Sephiroth but could still evoke their legacy. For example, Materia tied to spells or abilities from Final Fantasy 7 could serve as Easter eggs. Players might encounter flavor text descriptions referencing classic Final Fantasy lore, subtly reminding them of the connection between the two franchises.

Moreover, the Materia system could elevate Kingdom Hearts 4’s storytelling by tying it to gameplay. Imagine a Materia tied to Kingdom Hearts 4’s mysterious new Quadratum setting, offering unique abilities that reflect its otherworldly nature.

Materia Could Redefine Keyblade Customization

Keyblade upgrades in Kingdom Hearts 3 allowed players to tailor their weapons to their preferred playstyle by gathering materials to boost stats and unlock new abilities. While effective, this system could feel repetitive, especially in the endgame. Materia, on the other hand, would bring a dynamic layer of customization to Keyblades.

For instance, players could slot Materia into Keyblades to unlock abilities that change depending on the situation. A Healing Materia could turn one Keyblade into a support weapon, while an Attack Up Materia might make another ideal for high-damage output. Players could swap Materia mid-battle, adding a tactical element to combat and encouraging experimentation. This would ensure that even longtime fans experience something new and exciting while playing Kingdom Hearts 4.

Bridging FF and KH Universes with One Mechanic

A Materia system in Kingdom Hearts 4 could be the perfect compromise between honoring the legacy of Final Fantasy and maintaining the narrative focus on its original characters and worlds. As Kingdom Hearts 4 continues to evolve, the inclusion of Materia would be a thoughtful nod to Square Enix’s history, seamlessly blending its most beloved elements into a cohesive and exciting new chapter.
