Abilities/Powers: Yusuf is a very capable sword fighter and lethal hand-to-hand combat tactics. As an Assassin he is skilled in climbing and free-running, which is a form of sport that combines running, climbing and escape tactics into fluid motions. The trademark weapon of the Assassins is the hidden blade, which he also knows how to use, and the modified hookblade of the Constantinople Assassins. The hookblade allows him to slide across ropes easily for faster travel and makes for countering and evading blows in combat easier and more efficient. The hookblade also extends the ability to jump higher and hang onto precarious edges. He knows how to build a wide variety of bombs from many different materials, specifically tactical bombs, diversionary bombs, and lethal bombs.

As for Assassin oriented skills, he knows the Leap of Faith, which is when an Assassin dives off a high point of a building or ledge into anything soft or water without being harmed. He knows how to assassinate using his hidden blade with quiet methods and is also familiar with using foreign items, such as the parachute made by Leonardo da Vinci and, again, the bombs from the Chinese Assassins.
Items/Weapons: His custom sword, his Hidden Blade, and his Hookblade
