Unlike Eska, Spiro is a nervous perfectionist. He always makes sure that everything is in place. If something goes wrong, he starts to panic. Sometimes, he is level-headed and usually shakes it off, but it happens rarely.
Spiro is also shown to be a bit of a coward. He is afraid of ghosts and never runs towards the danger, unlike his red-haired friend. Despite this, Spiro is loyal and puts his cowardice aside to help fight the ghosts.
Even though Spiro is a perfectionist and coward, he is also kind at heart. When Eska was feeling bummed about messing up on her first day of fighting ghosts, he comforts her, even when she was sitting in the rain. Also, when he accidentally hurts Eska, he immediately takes his words back, and feels regrets about it.
He is also shown to be polite, especially to Disney princesses and when he's using table manners.
Spiro is also shown to be charming, like in Part-Time Day, when an elderly lady from Castle Hospital kept calling him into her room because she was infatuated with him.
Spiro is a slender, slightly short teenage bunny, three-inches above Eska. He has purple fur with a white face, long ears, and royal blue eyes. Unlike most bunnies, he does not have buck teeth.
Spiro sports a grey sweater with a brown strap going around his shoulder. He has dark grey pants with red at the bottom, and brown foot straps around both feet.
- Spiro is the fourth Disney coward character to be a sidekick to his female heroine, but the first not to fall in love with her.
