In their first appearance, these were the only known heroes at the time and were simply referred to as the Toa; it was recently revealed that the team's name at this time was the Toa Mata, in honour of the Great Spirit Mata Nui (see "Notes", below). When they were submersed in energized protodermis and came out with enhanced powers and abilities, Toa Tahu renamed them the Toa Nuva (though the Matoran language meaning of the word "Nuva" is unclear).
