H-221

H-221 was the nickname given to a Matoran by the Shadow Makuta Brotherhood.

Matoran
His life as a Matoran is unknown, except for the fact that he was an archivist.

Capture and Transformation
Years later the Shadow Makuta Brotherhood captured him and 49 others as a part of a project. When it was time for the results of it, he was one of the four Matoran who survived. When Teridax died, he along with everyone else evacuated the Matoran Universe and he is on Spherus Magna. Later, he went to live with the Shadow Makuta in their new base. They are now used as servants meant for fighting and killing Toa. They are now looking for the Toa Matrux to kill them with G-165.
