Secretary General Lex Luthor hindering their efforts. Recognizing the restrictions, Batman, Green Arrow, their respective protégés on the Team, and other Justice Leaguers resign in a pre-planned move to operate as vigilantes again. Black Lightning also resigns, but only to recover from an incident on Rann weeks earlier. Days later, King Viktor and Queen Ilona of Markovia announce their plans to help end metahuman trafficking, as their only daughter Princess Tara was abducted two years ago; only to be later assassinated by a metahuman. Markovia is placed under martial law with Queen Ilona's power-mad brother, Baron Fredric DeLamb, serving as regent until the eldest son, Crown Prince Gregor, turns 18. His fraternal twin brother, Prince Brion, wants to form a team that can continue his late parents' mission and learns from royal physician Dr. Helga Jace that he tested positive for the meta-gene. Nightwing and Oracle learn that the traffickers' labs are using a tar-like substance from Markovia and recruit Superboy and Tigress to help infiltrate the country. Dick also asks Jefferson to join, but he is hesitant due to his guilt over his actions and fluctuating abilities. Despite these, he ultimately agrees to join.
