Favourite Fictional Characters

My most favourite fictional character is Doraemon is a Japanese manga series created by Fujiko F. Fujio. This fictional character has a pouch which leads to another dimension, whenever he needs a gadget, he would just put his paws into his pouch and takes it out. What I like about Doraemon is the fact that he is cat. He travels back in time from the 22nd century to aid a schoolboy, Nobita Nobi. The gadgets that he finds in his pouch are hi-tech and amazing. Any way, who can time travel at this time and day?
