Z & T (aka Zone and Tech) are two clones of criminal, Portal (Portan Albert Edgar). These two "twins" are able to go through objects. Also, according to Ricardo H. B., when Tech is punched or injured it is Zone who feels it and vica versa. It is unknown if they are good or bad but it is known that the man they were cloned off of will be in G. I. Unit: 5 01. When first discribing them, Ricardo H. B. hinted that they were most likely badguys.
