This article contains plot details from the latest book.
Lex Dizznee is the younger brother of Dex Dizznee and is triplets with Rex and Bex Dizznee. The triplets are the subject of much controversy in the Lost Cities, as twins are rare and triplets are even more so. Rumors state that the triplets are a result of a bad match between Kesler (a talentless Elf) and Juline. They are the niece and nephews of both Grady and Edaline Ruewen and Kesler's multiple unnamed brothers and sisters. He enjoys teasing Dex, along with Bex and Rex. In Lodestar, he is seen at the sleepover implying that Dex has a crush on Sophie, and he loves to embarrass Dex in front of others, such as Fitz. Even though they tease each other a lot, he is inseparable from his brother and sister and is almost always seen with them. He was a level one at Foxfire in the second book of the series, Exile. Meanwhile, in the latest books, he and the triplets are in the middle of being a level two. This would set their ages at about twelve or thirteen. His mother is Juline Dizznee, who goes by Squall when she's with the Black Swan.
Much like Bex and Rex, Lex is a troublemaker. Dex says that Lex, Bex, and Rex once snuck into his closet and cut out the backsides to all his pants, and Lex's fellow triplets swung him off a chandelier using some ribbon.
The triplets are fraternal and are described as looking like two "mini-Dexes and a red-haired girl." They all share their father's strawberry blonde hair except Bex, and it is typically described as wild.
- Lex, Bex, and Rex are the reason Juline joined the Black Swan a few weeks after their birth.
- Lex is still learning to keep his hands to himself from girls in Lodestar.
