Twilight Saga Wiki

Marcus: the relationship identifier.

"He can see the relationships or connections people have to one another. For example, in a group situation he can easily pick out the leader, or sense the strength of the bond between mates or friends. He can also see where those bonds are weak."
―Entry on Marcus's gift[src]

Relationship identification is Marcus's power to sense relationships, or connections, between people.


Marcus uses this ability to sense the relationships of those around him (lovers, friends, family, etc.), along with the intensity of the ties that bind them, allowing him to see each individual's level of devotion to one another, and determine who would willingly die for another or turn traitor, given incentive. This power enables him to detect several different emotional links at the same time, be they ten, twenty or a hundred. He also uses it to sense how someone feels about the Volturi if they refuse physical contact with Aro.

When utilizing this skill on a battlefield, Marcus is quite dangerous, as he can identify both the strong and weak links of the enemy ranks, potentially ending the battle in the most efficient way possible.

This gift is unaffected by Bella Swan's mental shield, as he is able to read the intensity of her and Edward's relationship in New Moon.

"Marcus's gift is actually quite valuable in the hands of someone who knows how to use it. For example, imagine Marcus on the battle field. He sees the binding ties between the enemy the guard faces. He can tell who the leader is just by watching the way the others are tied to him/her. He can see how to destroy the resistance simply by picking off a few key people. He doesn't just see romantic relationships, but also ties of family and friends, loyalty and devotion. He can tell if any given person would die for another. Off the field of battle (as the Volturi rarely leave their home), Marcus's gift is valuable politically (for lack of a better word). It's an amazing gift in a diplomatic situation. Plus, when you're sitting on an empire, it's nice to be able to see when someone's loyalty starts wavering. Or if anyone is getting too fond of anyone else. Can you see the potential now? Marcus didn't get where he is with some fluff skill."
―Stephenie Meyer's description of Marcus's gift.


Aro found Marcus's power useful in detecting the emotional bonds of their enemies and how to use those bonds to their advantage. His power was so useful to the coven that Aro sacrificed his own sister to keep Marcus from leaving.

New Moon

"Marcus sees relationships. He's surprised by the intensity of ours."
―Edward, on Marcus's power.[src]

In New Moon, Marcus senses the intense bond shared by Bella Swan and Edward Cullen, presumably recognizing it as the one he once had with Didyme. Aro comments that it takes a lot to surprise Marcus, though Bella doesn't see any emotion on his face.

Breaking Dawn

In Breaking Dawn, Marcus uses his power to detect the bonds between the Cullens' allies and shares his information with Aro.

Similar abilities

  • Chelsea's ability to manipulate relationships bears a resemblance to Marcus's power, though she can also influence the emotional bonds between people while Marcus can only recognize them. It is presumed that Marcus can identify several emotional links at the same time while Chelsea can only detect those she wants to alter.
  • Eleazar

    Eleazar can identify the type and strength of another individual's gift in his presence, similarly to how Marcus can sense the strength of emotional bonds.
  • Edward Cullen

    Edward Cullen can read the minds of those around him. While a completely different kind of power, it also allows him to recognize the emotional bonds between people through their thoughts.
