This special introduces four new characters: Abo and Kado red and blue aliens wearing battle fatigues similar to Frieza's army, one tiny yellow alien, and a young Saiyan child who vaguely resembles Vegeta named Tarble. Though very little about the plot has been revealed, Tarble has arrived on Earth, being pursued by Abo and Kado. (Source: Wikipedia)
