Diana gave Bruce a silver talisman shaped like the mark of Hecate in the Absolute Universe. It functions like a summoning token, letting Bruce call on her when needed.

Quick context

  • Some writeups describe it as a flash drive or USB in shorthand, but the more specific comic description is the Hecate talisman.
  • The gift is sometimes called her Hiketeia , a nod to both the ancient custom of supplication and the Batman/Wonder Woman story reference.

In plain terms

It is not just any thumb drive; it’s a magical token tied to Diana’s power and their alliance.

TL;DR: Diana gave Bruce a Hecate-shaped silver talisman, not an ordinary drive, in the Absolute Universe.
