Justice League (Justice League Vol. 3 #33)

BATS OUT OF HELL, FINALE

The Justice League is defeated and carried by Murder Machine to the Cosmic Tuning Fork, where many other heroes have already been tied up. Cyborg, dismembered, has his Mother Box flooded with energy from the Dark Multiverse by The Batman Who Laughs, who's trying to extract out of him something called "Element X": this results in Victor seeing over and over again ways in which he could lose and his worst nightmares could win over him. Suddenly, an intermittent sound from inside him stops, and a voice announces: "You are ready, Victor Stone".

Victor finds himself floating in his own mind, with his Mother Box in front of him. It explains to him that he's ready for his true programming, which comes from the Element X at its core, "the purest, brightest metal in the cosmos, from the World Forge itself". It tells Victor that there are many like him (i.e. many creatures who connected to a Mother Box), but he's the only one who resisted from achieving his perfect form, which would delete his original programming: in other words, it would cancel his own identity to get him to his fullest potential. To convince him it is the right choice, Mother Box shows Victor the Multiverse, with its 52 Universes and countless life-forms, who would die if he didn't do anything. Only if he becomes one with the Multiverse will he be able to defeat Barbatos and his Dark Knights. Victor is almost convinced, when a faraway voice stops him. In the form of a glowing Raven, she tells him she's been watching him and that his heart is what's special in him, not his Mother Box, so he shouldn't leave his consciousness. Victor seems persuaded to do what Mother Box says, though, so he starts making an intermittent sound, merging with it.
