Codex and Lex in the opening intro.


Bookworm AdventuresEdit

He appeared as leader of books, mentor of Lex and the Head Librarian in the Great Library. He has a special magic pen which he uses most often. Although he helped Lex, he appeared to be the main antagonist. He claimed before being defeated by Lex that he will never save Cassandra. One possibility is meanwhile in Book 1 he told Lex that he must be pulled out of the book to rest but Lex refuses. This is somehow one possibility that he REALLY never wanted Cassandra to be saved. Here is the dialogue that appears after defeating Codex:

Codex: Recalcitrant verminous annelid! You have not defeated me yet! I'll simply build a bigger army, and sadly your timer has reached ZERO.


Codex: Any last words, gullible grub? 


(Codex is destroyed)
