Throughout the production of a series, a lot goes on behind the scenes in regards to planning and design, which often go through multiple stages before resulting in the final version that is seen on screen. Some concepts and ideas can have an effect on the show and characters, and unexpected occurrences during production can also lead to changes and additions to the plans for the show.
Leonardo Lionheart alludes to the Cowardly Lion from The Wonderful Wizard of Oz. This allusion has had the following influences on the character and show:
- The name "Leonardo" means "lion" and "bold" in Spanish. Both his first and last names reference the Cowardly Lion himself.
- Lionheart is a lion Faunus.
- Lionheart is shown to be incredibly fearful of Salem, a reference to the Lion's cowardice.
- In the original book, the Wicked Witch of the West captures the Lion and tries to force him to work for her. Lionheart works for Salem in the series.
- His emblem is a lion's head.
He may also have a secondary allusion to the famous polymath, Leonardo da Vinci.
- The two share the same first names.
- Lionheart's weapon, Stalwart, resembles a painting pallet – in reference to da Vinci's famous paintings.
- The statue of Jinn at Haven Academy likely references da Vinci's sculptures.
- His pocket watch resembles da Vinci's clock; which was famous for being the first to measure both minutes and hours.
Lionheart's emblem is a stylized depiction of a lion's head. This emblem appears on one of his possessions:
- His pocket watch.
- While Kerry Shawcross admitted that he was sure they weren't going to properly show Leonardo Lionheart's death, they actually did mocap the death scene with Joel Mann acting it out in case they did show it on-screen. However, this version was never used since Lionheart's death happened off-screen.
