Leo rose to the throne of the Eastern Roman Empire in 457 after the death of Emperor [[Marcian]] ({{reign}}450–457).{{sfn|Jones|Martindale|Morris|1980|pp=714–715}} [[Aspar]], the {{lang|la|[[magister militum]]}}, selected him for this position, much as he had selected Marcian himself.{{sfn|Jones|Martindale|Morris|1980|pp=714–715}}{{sfn|Ostrogorsky|1956|p=61}} Despite being half-[[Alans|Alanic]] and half-[[Goths|Gothic]], Aspar held much influence in the empire since the mid fifth century,{{sfn|Nathan|1998}}{{sfn|Lee|2013|p=96}} and wielded significant power over Marcian and Leo.{{sfn|Ostrogorsky|1956|pp=61–62}} Basiliscus served as a military officer under Leo, and was made [[Roman consul|consul]] of the East for 465, with [[Flavius Hermenericus]] as consul of the West.{{sfn|Elton|1998}}{{sfn|Jones|Martindale|Morris|1980|p=212}} Basiliscus was granted the rank of {{lang|la|[[Magister militum#Per Thracias|magister militum per Thracias]]}} in {{circa}} 464, and held it till 467/468; during this period he won many victories in Thrace against the [[Huns]] and Goths. He led troops in a war against a mixed group of the two in 466/467, along with [[Anagast]], Aspar, and [[Ostrys]].{{sfn|Jones|Martindale|Morris|1980|p=212}} He was made a {{lang|la|[[Patrician (ancient Rome)|patricius]]}} at some point, first mentioned as such in 468.{{sfn|Jones|Martindale|Morris|1980|pp=212–213}}

Around 466, Leo attempted to free himself of Aspar's control. He utilized the support of the [[Isaurians]], marrying the Isaurian chieftain [[Zeno (emperor)|Zeno]] ({{reigned}}474–475, 476–491) to his daughter [[Ariadne (empress)|Ariadne]], in exchange for support. This resulted in a significant change to eastern imperial policy, notably ending the policy of ignoring the requests from the West for military aid.{{sfn|Ostrogorsky|1956|p=61}} After [[Anthemius]] ({{reign}}467–472), Marcian's son-in-law, was installed by Leo as Western emperor on 12 April 467, an embassy was sent to the [[Vandal]] King [[Gaiseric]], to inform him as well as warn him not to interfere in [[Italy]] or the Western Roman throne; Gaiseric accused them of violating a prior treaty, possibly enacted in 433, and prepared for war. Rumors may have spread in Constantinople that the Vandals were preparing an invasion of [[Alexandria]].{{sfn|Jones|Martindale|Morris|1980|p=498}}{{sfn|Bury|1923|p=335}} As a result of this, in 468 Basiliscus was given command of an expedition against the Vandals,{{sfn|Elton|1998}}{{sfn|Ostrogorsky|1956|p=61}}{{sfn|Jones|Martindale|Morris|1980|p=213}} and likely promoted to {{lang|la|[[magister militum praesentalis]]}} at that time.{{sfn|Jones|Martindale|Morris|1980|p=213}} It is said that the fleet consisted of 1,113 ships, with more than 100,000 men under the command of Basiliscus,{{efn|Historian [[Warren Treadgold]] argues for a figure of 400,000 total men, as given by Byzantine administrator [[John the Lydian]], arguing that Procopius' figure of 100,000 excludes the sailors and oarsmen.{{sfn|Treadgold|1995|pp=190–191}}}}{{sfn|Bury|1923|p=335}} including mercenaries from as far as [[Öland]], [[Sweden]].{{sfn|Kulikowski|2019|p=224}} According to Bury, Leo was influenced by both Verina and Aspar in his selection of Basiliscus, whom he describes as both "incompetent and untrustworthy"; he further states that Aspar intentionally chose a poor commander, to prevent Leo from becoming stronger by way of weakening the Vandals.{{sfn|Bury|1923|p=335}} Historians [[Gerard Friell]] and [[Stephen Williams (historian)|Stephen Williams]] dismiss this, but accept that Verina pushed for his appointment and that Aspar did not object.{{Sfn|Friell|Williams|2005|pp=178–179}} Historian [[Peter Heather]] points out that, at this point, Basiliscus had just returned from considerable success on the Balkan frontier of the empire.{{sfn|Heather|2007|p=401}}

[[Marcellinus (magister militum)|Marcellinus]], a West Roman commander, was sent to capture [[Sardinia]], and then to sail to link up with the Eastern armies near [[Carthage]], the Vandal capital. Basiliscus was to sail with the bulk of the forces directly to Carthage, and the Eastern {{lang|la|[[comes rei militaris]]}} [[Heraclius of Edessa]], was to gather up Eastern forces in [[Roman Egypt|Egypt]], disembark in [[Tripolitania]], and then to approach Carthage by land; forcing the Vandals to fight in three areas. Marcellinus seized Sardinia with little trouble, and Heraclius took the fortress of [[Tripoli, Libya]], and both headed to connect with Basiliscus' forces.{{sfn|Stewart|2020|p=106}}{{sfn|Bury|1923|p=336}} Basiliscus's [[galleys]] scattered the Vandal fleet near [[Sicily]], something said by [[Procopius]] to have caused Gaiseric to give all up for lost, fearing a decisive blow to capture Carthage. However, Basiliscus did not press his advantage and rested his forces in [[Cape Bon]], {{convert|60|km|mi}} from Carthage.{{sfn|Bury|1923|pp=336–337}}{{sfn|Heather|2007|p=402}} This was a strategic location as it was near the port of [[Utica, Tunisia|Utica]], which, unlike Carthage, was not blocked off with a chain, and the winds would push opposing ships into the coast.{{sfn|Heather|2007|p=402}} According to historians [[Michael Kulikowski]], Friell, and Williams, Gaiseric feigned interest in peace and proposed a five-day truce, in order to allow himself time to prepare.{{sfn|Kulikowski|2019|p=224}}{{Sfn|Friell|Williams|2005|pp=178–179}} Basiliscus accepted, possibly in favor of Aspar who opposed the war, in order to achieve a compromise with the Vandals.{{Sfn|Friell|Williams|2005|pp=261–262}} Heather notes that the Romans strongly intended to avoid a naval engagement,{{sfn|Heather|2007|pp=401–402}} and archaeologist [[George Bass (archaeologist)|George Bass]] suggests this might be the reason that Basiliscus hesitated to strike the Vandals.{{sfn|Heather|2007|p=310}}{{sfn|Bass|1972|p=134}}

Gaiseric assembled a new fleet with a number of [[fire ships]] and, aided by good winds, attacked the Roman fleet at the [[Battle of Cape Bon (468)|Battle of Cape Bon]]. The Roman fleet was routed by the combination of the fire ships, bad winds, and surprise, with half of it being destroyed. Basiliscus fled with the remainder of the fleet to Sicily, to consolidate with Marcellinus's forces; their morale and supply might have brought a victory, but Marcellinus was assassinated, possibly on [[Ricimer]]'s orders. Heraclius, who had not yet reached Carthage, returned to the Eastern Roman Empire by the path he came, and Basiliscus returned to Constantinople.{{sfn|Kulikowski|2019|p=224}}{{sfn|Bury|1923|pp=336–337}} The total cost of the armaments for the fleet was {{convert|130000|lb}} of gold,{{efn|Procopius gives this figure of {{convert|130000|lb}} of gold, whereas John the Lydian gives a figure of {{convert|65000|lb}} of gold and {{convert|700000|lb}} of silver, which, using the 1:18 ratio of gold to silver, would equal roughly {{convert|104000|lb}}; John seems to derive this from Candidus, who states that the treasuries of the [[Praetorian Prefect]]s, both east and west, contributed {{convert|47000|lb}} of gold, the coffers of the [[Sacred Largess]] {{convert|17000|lb}} of gold, 700,000 of silver partially from the Private Estates, largely made up of confiscated property, and partly from the reserves of Anthemius.{{sfn|Bury|1923|loc=Chapter X fn. 95}}}}{{sfn|Ostrogorsky|1956|p=61}}{{sfn|Bury|1923|p=337}} more than the entire treasury of the Eastern Empire, causing the Eastern Empire to waver above bankruptcy for more than 30 years.{{sfn|Bury|1923|p=337}}

Upon his return to Constantinople, Basiliscus sought refuge in the [[Hagia Sophia|Church of St. Sophia]], before Verina interceded on his behalf to have him pardoned by Leo. He may have remained {{lang|la|magister militum praesentalis}} after this,{{sfn|Jones|Martindale|Morris|1980|p=213}}{{sfn|Kulikowski|2019|p=241}} but largely lived a life of retirement at [[Neapolis (Thracian Chersonese)|Heraclea]] on the [[Propontis]].{{sfn|Bury|1923|p=337}} Aspar was suspected of inducing Basiliscus to betray the expedition, sympathizing with the Vandals, and promising to make him emperor in place of Leo.{{sfn|Jones|Martindale|Morris|1980|p=167}}{{sfn|Bury|1923|p=318}} Friell and Williams also reject this, commenting that the need to find a scapegoat is common in such disasters and that the accusation is implausible.{{Sfn|Friell|Williams|2005|pp=178–179}} One source, [[Hydatius]], states that Aspar was stripped of his rank for voicing his suspicions, but historians [[A. H. M. Jones]], [[John Robert Martindale]], and [[John Morris (historian)|John Morris]] state that this is almost certainly a confusion relating to the disgrace of [[Ardabur (consul 447)|Ardabur]], his son, who had informed the [[Sassanid Empire]] of Roman military weakness.{{sfn|Jones|Martindale|Morris|1980|pp=136 & 167}}

Aspar regained power after the failure of the African invasion, and his son [[Patricius (Caesar)|Patricius]] became the presumptive heir to the throne by marrying Leo's daughter [[Leontia Porphyrogenita]] in 470.{{sfn|Ostrogorsky|1956|p=62}} Historian [[L. M. Whitby]] suggests this may have been a ploy to lull Aspar into a sense of security.{{sfn|Whitby|2015}} When anti-German sentiment rose up, Leo first quarreled with Aspar and then had him assassinated over suspicions of conspiracy.{{sfn|Ostrogorsky|1956|p=62}}{{sfn|Jones|Martindale|Morris|1980|p=168}} Basiliscus supported Leo in his power struggle against Aspar, and subsequently [[Theodoric Strabo]], in 471/472.{{sfn|Elton|1998}}{{sfn|Jones|Martindale|Morris|1980|p=213}} Aspar and Ardabur were killed in 471, and Patricius, severely wounded, was stripped of his position as {{lang|la|caesar}} and divorced from Leontia. After this, Zeno gained more power over the court.{{sfn|Ostrogorsky|1956|p=62}} Theodoric Strabo attempted to avenge Aspar and marched against Constantinople, but was pushed back by Basiliscus and Zeno. A little later, he sent a series of demands to Leo in the capital and attacked [[Arcadiopolis]] and [[Philippopolis (Thrace)|Philipopolis]], but was forced to negotiate soon after due the lack of supplies.{{sfn|Jones|Martindale|Morris|1980|pp=1073–1074}}
