Basil of Baker Street

Basil of Baker Street, or Basil for short, is the dauntless hero and the main protagionist in Disney's 1986 hit The Great Mouse Detective. He is voiced with appropriate Polish and sophistication Barrie Ingham.

Personality
Basil is a take off of the classic Sherlock Holmes character, modeling his career after the famous detective's. Moody, dramatic, and a model of English snobbery, but brilliant, he lives in a flat below Holmes's residence, and is a genius of mystery. Mice come from all over England for his assistance.

Role in the film
In the film, when Dr. Dawson meets a lost and frightened Olivia Flaversham, desparately searching for Basil to help her locate her kidnapped father, he helps her find Baker Street. Before long, all 3 are involved in a maze of mystery and intrigue, looking for clues and realizing that all clues point to one person--Basil's arch enemy, the nefarious Professor Ratigan. Quick on his feet and in his mind, Basil and Dawson are able to track down Ratigan's hideout when Olivia is kidnapped as well.

Basil's keen and penetrating mind save the day when, after a near coup of the English royaly and a fierce, animalistic battle on Big Ben, he reunites Olivia with her father, and saves England, with only a few scratches and a smile on his face. At the end, he and Dawson become partners.

House of Mouse
Basil made a few cameo appearances on House of Mouse. His most notable cameo is him keeping Dawson away from a mousetrap that Ratigan has set for them in the episode "Donald's Lamp Trade".
