In my case, Doreamon is the most my favourite character . The main content is about friendship. He comes from future and lives as a second son of Nobita's family.  He is so adorable because he has a magic pocket which can help everyone in any cases .

 Morever Doreamon is so kind, so his best friend, Nobita, who always ask him for helping his lazy and weakness. I like his characteristic because he always  takes care everyone around him unconditionaly. Sometimes, he is a little childish but still cute with his performance. Furthermore, he is friendly and intelligent. When Nobita has problems , Doreamon always try his best to help friend. However, Doreamon just helps Nobita in the right cases, and he usualy teaches Nobita life lessons through daily activities which help  Nobita to realize his mistakes.
