As with the original cataphracts, the Leonian/Nikephorian units seemed to have fallen out of favour and use with their handlers, making their last, recorded appearance in battle in 970 and the last record of their existence in 1001, referred to as being posted to garrison duty. If they had indeed disappeared, then it is possible that they were revived once again during the Komnenian restoration, a period of thorough financial, territorial and military reform that changed the Byzantine army of previous ages, which is referred to separately as the Komnenian army after the 12th century. Emperor Alexios I Komnenos (1081–1118) established a new military force from the ground up, which was directly responsible for transforming the aging Byzantine Empire from one of the weakest periods in its existence into a major economic and military power, akin to its existence during the golden age of Justinian I. However, even in this case, it seems that the cataphract was eventually superseded by other types of heavy cavalry.
