Because Batman, Flash, Green Arrow and their protégés interfered with the ritual, Kobra had to step up the rest of the procedure. He used a special dagger to prick his brother, acquiring a tiny amount of his blood, which he then fed to a snake. Kobra also drank cobra venom and some of the blood, and prepared to finish the ritual. Jason pleaded for his brother to stop, but it was to no avail. Dr. Burr was absorbed into the dagger, which gave Kobra snake powers. After the mutated Kobra was pricked with the dagger, the mutation was undone and Jason Burr was restored. His brother was nowhere to be seen.
