Lelouch Free Lamperouge/vi Britannia/Batman

The Leader of the newly formed Justice League.

Adaptational Badass: As a result of being composited with the premier Badass Normal of the DC Universe, Lelouch is a far better fighter than he was in canon.
Adaptational Heroism: Lelouch inherits Batman's belief in Thou Shall Not Kill, which is leagues better than his canon self at his worst.
Bad Powers, Good People: Has a fragment of the Anti-Life Equation that works similar to his Geass, and he's the leader of the Justice League.
Green-Eyed Monster: While he doesn't outright go villain because of it, the encounter with the Seven Deadly Sins confirms that he is more than a little jealous of how everyone else on the team has superpowers while he doesn't.
Ship Tease: Gets a ton of moments with Kallen. Eventually leading to a Relationship Upgrade between them.
The Team Normal: The only member of the Justice League without superpowers. Initially.
Villain Respect: Multiple times Darkseid compliments Lelouch and his cunning, saying he would make the perfect heir to his kingdom.
