This card is similar to "Boar Soldier". Both monsters are Level 4 with 2000 ATK that have an effect that destroy themselves if they are Normal Summoned and they both have a second effect that makes them lose ATK if the opponent controls monsters.
This card's name is likely derived from Nubia, a place in Egypt, which follows in with the Egyptian theme of the original Yu-Gi-Oh! (manga) series.
This card's artworks are both taken from Yu-Gi-Oh! Duelist Duel 128: "Teamwork" specifically from the panel where this monster is shown being Summoned.
