Alienated

January 5: Bumblebee, Blue Beetle and Bibbo Bibbowski try to detain a Kroletean but it escapes.

January 6: Miss Martian shares what she has learned about the Justice League's attack on Rimbor during the missing 16 hours with Nightwing and several Leaguers. Later, she forcefully probes the mind of a captured Kroletean and uncovers the location of their base. Members of the Team and the League investigate the island but are discovered and a fight ensues, during which the enemy is revealed to be Aqualad, who left the team in anger after Aquagirl died when they were unable to save her, as well as discovering that Black Manta is his father. Aqualad escapes, and a bomb planted by the enemy seemingly obliterates the island and most of the Kroloteans present.

January 7: He reports to Black Manta, who in turn reports to the Light as Ocean-Master's replacement.

January 26: The six Leaguers accused of attacking Rimbor, along with Hawkman and Icon, leave Earth with the captured Krolotean to try and resolve the dispute peacefully, bidding a temporary farewell to their proteges in the process.
