Alan in Ch.3, 262 ft tall, was the last remaining brother in the Whitman family, and he along with his new son, Damon, and the Mecha, would travel back to Akrida Island after the Mecha reported to Alan in the morning that the night prior, Locust, in a new fourth form, had snatched his other son, Dexter, away. So far in Ch.3, Alan got to Akrida island with the pair by his side, where he would immediately see the giant new Locust standing there, turned away from him. After cursing Locust for doing such malevolent things again, Locust would use his beam to immediately take Mecha out of the rest of part one, to which Big Bro would retalliate and hit Locust with his own brand new blue beam. Big Bro would end up being parylized by another beam of Locust, and he'd be forced to just watch as his sons get taken again. Once the paralysis wore off, he'd see two small mechas controlled by locust, that he would battle and get knocked out by before waking up in a cave, being held in place by the two mechs. He would end up busting out of that cave.

Alan Remake, at 184 feet tall, was the strongest and most relentless version of Big Bro we have ever seen on film. Granted he was 16 in the remake continuity, not 11. He was shown to be EXTREMELY protective of his brothers in the Remake film of Ch.1, and very powerful & strong. He possessed a very powerful pyro-beam which he used SEVERAL times throughout the film to combat Locust. Unlike the white beam in the original trilogy which temporarily stunned locust, this beam actually dealt pain and damage to the beast. Big Bro was also extremely agile and acrobatic when it came to fighting. He could spin around to slash Locust with his tail as well. In the fight with Pre-1 Locust, he showed off a new ability: a Pyro-Pulse; a very powerful thermic pulse which could destroy acres of forest and severely damage opponents. In the fight with F2, he introduced a version of this attack; a more powerful, blue pulse.
