In Constantinople, the Almogavars mainly appeared in Byzantine-controlled districts. Roughly comparable to Italian Brutes and Colonial Grenadiers, they fought with heavy weapons and wore thick armor; they could not freerun and were significantly slower in combat than other classes of soldiers. Like the Varangians, the Almogavars were employed by the Byzantines. Due to their thick armor, they could not be killed with a single bullet or crossbow bolt.
- Historically, the Almogavars were soldiers of Aragonese and Catalan origin. They were known to have worked as mercenaries for the Byzantine Empire.
- In reality, the Almogavars were light troops, rather than heavily armored axe-wielders. The in-game Almogavars' design actually more resemble the historical Varangians, and vice versa.
- The Almogavars, like the Janissaries – except in some missions – were always found carrying the same weapon: the Almogavar Axe.
- The Almogavar Axe could also be used as a weapon, after completing "The Champion, Part 1" memory, or taking the axe from a dead Almogavar.
- Unlike Brutes in Assassin's Creed II and Assassin's Creed: Brotherhood, Almogavars could be killed with a counter if their attack was not the overhead smash while using a medium weapon or short blade.
- Almogavars appeared to have a unique weakness to Datura bombs, as evidenced by both the memory "Piri Reis: Datura" and usual gameplay; the poison killed them about twice as fast.
- The etymology of Almogavar is likely to lie in Arabic, with both al-maghāwīr ("scout") and al-muqafir ("raider" or "devastator") as suggested sources.
