Frank was an alias adopted by one of the so-called "Travelers" from Tau Alpha C. Since Tau Alphan names proved unpronounceable by humanoid tongues, he went by the alias, coined for uncertain reasons by an unidentified \Federation individual. While some postulated an allusion to "Frankenstein" (due to Frank's extreme height, a natural physical trait of most Tau Alphans), it was more likely derived after Earth physicist Frank J. Tipler.
In 2382, Frank joined the UFS Arcadia's time-traveling mission to the future via the Nexus, and helped Neria April to resolve a temporal paradox involving Tolian Soran. (Star Trek: Arcadia)
