Task: Question Answering
Input (English): Passage: Boo-Boo Bear wakes up from winter hibernation, excited about the new Spring. Then Yogi Bear wakes up, his only interest finding some food to eat. Cindy Bear unsuccessfully tries to woo Yogi. After Ranger Smith thwarts Yogi's latest attempts to grab some food, Yogi gets angry and convinces the Ranger to transfer him out of Jellystone National Park. Smith prepares Yogi to be sent over to the San Diego Zoo along with an identification tag. Yogi first says goodbye to everything, but tricks another bear named Corn Pone into going to California instead of him and Boo-Boo and Cindy remain unaware of this, thinking Yogi has departed for good.
Soon, Yogi is stealing food from all over the park under the alter ego "The Brown Phantom", but Smith believes it is another bear. He threatens whoever it is to be sent to the zoo. Cindy, wishing to be with Yogi at the zoo, angers Smith into mistakenly sending her away. However, she gets sent to the St. Louis Zoo instead, as the San Diego Zoo does not need any more bears. When she realizes her true destination, she gets very sad, crying since she knows she would be far from Yogi now.
Late that night, Cindy falls out of the train and becomes lost. A traveling circus is looking for a great act to raise their ratings, when suddenly, their dog runs off and scares Cindy into walking on the telephone wires, the perfect opportunity for the circus. 
Question: What is the name of the character who calls themselves "The Brown Phantom"?
Output (English): Yogi.
