Dexter & Damon

Dexter, one of the twin sons of Alan during Chapter 3, was the one who ended up getting kidnapped by Locust during the first part of the film. Both he and his twin brother look alike and resemble Big Bro. They are the sons of Alan and Bella (his divorced wife). His and Damon's heights in Ch 3 were 91'10 ft (28m), and their lengths were 400.3 ft (122m). Dexter was known to be the smartest of the two.

Damon was the "dumb" one of Big Bro's sons, being mentally unable to process things and puking when waking up.

After waking up and Alan being told that Dexter was gone, Alan, Damon, md the Mecha went to Akrida zisoand to contront Locust once and for all, except when Alan got paralyzed by Locust's beam, Locust seized the opportunity to kidnap Damon as well.
