King of Fighters RX Project '00 (拳皇RX) is a three-volume manhua series that was officially sponsored by SNK-Playmore Hong Kong. These books are a part of the KOF RX series (RX standing for "Remix") with two more books that take place during the Orochi saga.
The NESTS saga version was illustrated by Ricky (力奇, which translates to "Lucky") who also did a manhua series for The King of Fighters R-2. It covers the entire NESTS chapter with the first two volumes primarily focusing on the Zero Project. Kula and both forms of Zero are shown somewhat earlier than their premiere in the series. Most events remain relatively the same until the final volume.
