Tabu was discovered in the beta files  but ever since then he has been canceled. Thematic similarities suggest he might have been inspired by the Dota 2 Hero Zharvakko, the Witch Doctor, and visual and gameplay similarities seem to indicate he might have been reworked into who is now 20px Swain.
Confirmation of his cancelation came in the 2010 Harrowing map skin for Summoner's Rift, where a coffin containing Tabu (along with two others each containing 20px Averdrian and 20px Gavid) could be seen, effectively serving as the final 'nail in the coffin'.
