Owlowiscious

Owlowiscious or Owloysius (see below) is Twilight Sparkle's pet horned owl. His first (and so far only) appearance was in Owl's Well That Ends Well.

Personality
Although incapable of speech, Owlowiscious is highly intelligent. Also shows to be brave and willing to help the others. Not much is known of his personality at the time, as he seems to be collected and inexpressive.

History
He first appeared when he retrieved one of Twilight Sparkle's papers, which had blown away in the wind. Noting the cold weather outside, Twilight invited the owl to stay the night in her house. Twilight then spent a good portion of the night working on her paper on comets, with Owlowiscious assisting. Twilight decided to take Owlowiscious on as a second assistant to lessen the workload on Spike, who she had noticed was regularly working himself to the point of exhaustion.

Spike was initially quite jealous of Owlowiscious and suspected that he was trying to replace him as Twilight's assistant. His fears only got worse when Owlowiscious discovered a book that Spike had accidentally burned and hidden in a bookshelf. Due to this, Spike attempted to frame Owlowiscious for messily killing a mouse, using ketchup and Opalescence's toy mouse. However, Twilight and Owlowiscious walked in on Spike preparing the "crime scene," with Twilight expressing disappointment in Spike's actions. Distraught, Spike decided to run away to the Everfree Forest.

Later that night, Owlowiscious found Spike's ketchup-stained tracks and helped Twilight find and rescue the young dragon from an enraged fully-grown dragon. With Twilight's help, Spike realized that Owlowiscious was not trying to replace him and apologized for his actions.

Trivia



 * In the show the name was pronounced somewhat like "alo-wishes" and correct spelling puzzled many fans. Someone suggested a real name "Aloysius" (it's also how the closed captioning spelled it). Finally Lauren Faust clarified: it's spelled "Owlowiscious" in the script, though "Owloysius" might be more correct.
 * One Hasbro toy of Twilight Sparkle comes with a owl figurine. This owl, however, is not Owlowiscious, as it is pink and has a different body shape.
