Le'noir (松 黒蔵 Matsu kuro zō) is an enemy that only appears in the Stories of Legend (since Sub-chapter 23, Dead End Night)
Black variant of Le'boin, has slightly longer attack range than its White counterpart, with higher health and attack damage.
Using Ururun and Bahamut with good meatshielding is the general way to deal with Le'Noir, but it is very tedious.
However, an extremely strategic method to defeat Le'Noir has been found, involving Major Leaguer Cat and other enemies. If Le'Noir is protected by other bulky enemies that do not get easily knocked back, do not send out any attackers other than Major Leaguer Cat, though you still need to meatshield well. He will be able to consistently chip off health from Le'Noir, with the other bulky enemies still intact. Thus, you'll be able to defeat Le'Noir by cleverly making use of other enemies. Works extremely well in late-game stages like Leadfoot Drive and Angry Fighting.
