In Assassin’s Creed II, which Renaissance artist provides inventions and equipment to Ezio?

Leonardo da Vinci provides inventions and equipment to Ezio in Assassin’s Creed II.

Leonardo is portrayed as Ezio’s close friend and an inventive ally. He helps decode pages from Altaïr’s Codex and develops or maintains several tools that support Ezio’s missions, including improvements to the hidden blade. His workshop moves as Ezio’s journey progresses through Renaissance Italy.

The game uses Leonardo’s real historical reputation for engineering, painting, anatomy, and scientific inquiry as part of its fictional narrative. Some devices associated with him in the game are imaginative adaptations rather than confirmed historical inventions. Leonardo is also not the protagonist: Ezio remains the playable Assassin. Michelangelo, Raphael, and Donatello were real Renaissance artists, but they are not the artist who serves as Ezio’s principal inventor and technical ally.
