Lyle first came to prominence as penciler on DC Comics' Starman vol. 1 where he worked with writer Roger Stern.

He went on to work on the first Robin limited series with writer Chuck Dixon. The series was an enormous surprise hit, prompting many reprintings of the first few issues as well as two sequel miniseries ... Robin II: Joker's Wild and Robin III: Cry of the Huntress ... both of which reunited the creative team of Dixon and Lyle.

Lyle's next project was The Comet for DC Comics' Impact Comics imprint, which he pencilled and plotted with writer Mark Waid contributing the scripts.

Lyle then moved to Marvel Comics where he worked on Spider-Man (with writer Howard Mackie), The Punisher vol. 3 (with writer John Ostrander), and Warlock (which he wrote himself).

He is also the artist on the comic Chickasaw Adventures.

He currently teaches sequential art at the Savannah College of Art and Design.
