Krax

Krax was a Ferengi male who lived in the 24th century. He is the son of former Grand Nagus Zek.

In 2369, Zek was hoping to retire but was unsure of whether Krax was suitable to succeed him. He named Quark as his successor and then faked his own death. Disappointed that Krax acted "like a Klingon" in his attempt to become Nagus, Zek stayed in his position as the Ferengi leader. 

Krax later became Rom's First Clerk when Rom became Nagus. As First Clerk, Krax was allowed to sit with the Economic Congress of Advisors. Krax helped to stop Brunt from unseating Rom.
