Like his modern counterpart, Original Yoyo is shown to be quite friendly, playful and funny towards their friends. It is emphasized in "Les Pyjamasques et le croque-chaussettes" that Original Yoyo will tell lies and forgets about the Night of the Black Moon.
Original Yoyo is identical to his mainstream counterpart, except that his paws and feet are white, has a different arrangement of stripes, and his cat belly is smaller.
However, like his mainstream counterpart, he is pint-sized rather than being the size of an average seven years old.
