Nero L (ネロ・L Nero L?) is a boss from Rockman Xover that appears in World 12 and the Battle Tower. He is the leader of Blu D, Rosso M, Oro S, and Verde R. He has two attacks, one where he jumps in the player's direction and quickly falls with his sword for a strong impact slash, and other starting with him dashing to stab the opponent and following with a rising slash. When all main worlds are complete and all their bosses reach level 8, Nero L appears and decides to help OVER-1 by giving him a Portal Charger (ポータルチャージャー) so he can rescue the missing Mega Man heroes.
