The following children have been born to Imperator Caesar Flavius Valerius Felix Leo Theodoros Basiliscus Marcellus Pius Invictus Augustus and Imperatrix Caesarissa Flavia Valeria Nousha Sasan Augusta over the past several years:

• Caesar Flavius Valerius Zeno Basiliscus Marcellus, born in AD 534;

• Caesarissa Flavia Valeria Ariadne Basilisca Marcella, born in AD 536;

• Despótēs Caesar Flavius Valerius Leo Basiliscus Marcellus Porphyrogenitus, born in AD 542;

• Caesarissa Flavia Valeria Theodora Basilisca Marcella Porphyrogenita, born in AD 542.

Of those, Zeno and Ariadne were born while Felix was still Exarch of Egypt, while the twins Leo and Theodora were born after Felix reconquered Constantinople. As such, Leo formally ranks above Zeno in the line of succession, despite being younger.
