Beckett and Myles Fowl are the younger twin brothers of Artemis Fowl II. In the Time Paradox, their first appearance in a book, they are age two. They were born to Artemis Fowl I and Angeline Fowl after Artemis II departed to Limbo to help save the Demon fairy family with Qwan, No. 1, and Holly Short in The Lost Colony. Artemis first learns of his younger siblings' existence upon his return from Limbo. In the scene, Butler alludes to the fact that Artemis is now the eldest Fowl child. Both are briefly mentioned in The Atlantis Complex and are now four years of age.
