Alex Kidd appears as a short boy with large ears and slightly monkey-like features, a red and yellow jumpsuit, and oversized hands. Sometimes he appeared as a teenager, although the only time his exact age has been stated, he was stated to be 14 years old. However, being a 14-year-old Arian was somewhat different to being a 14-year-old human. The games state that he lived many hundreds of years previously.
