After Helena Bertinelli came to Sicily, she met Silvio, sleeping with him numerous times and gaining his trust. He began training Helena in a number of disciplines, before she left to avenge her father in Starling City.
- Peak of human physical condition: As a high-ranking member of La Morte Sussurrata, Silvio had to have been in peak physical condition. This is especially apparent in his ability to train Helena Bertinelli.
- Expert hand-to-hand combatant: While training Helena, Silvio was shown to be able to overpower her, a skill likely honed due to his high-ranking status as part of La Morte Sussurrata.
