The Malebranche is an enemy in Final Fantasy XIII-2.
Malebranche at plain sight is a stronger version of Wladislaus. It always appears alone. At first Malebranche's attacks can deal approximately 1000 HP damage to a single member. As his HP goes down Malebranche will start switching swords with Unrelenting Blade at first and then with Peerless Blade when he has lost about 2/3 HP, increasing his power even more.
With a fairly leveled party the player should be able to beat it. It is a good idea to start the battle with Cerberus paradigm to establish the chain gauge and then switch to Tri-disaster and start barraging Malebranche with spells to build up his chain gauge.
The party can use a Sentinel along with a Medic or two to recover lost HP from Malebranche's initial attacks. The party should switch between Cerberus and Tri-disaster to keep the attacks going and eventually Malebranche will fall before unleashing any of his powered attacks.
The Malebranche were a group of demons that guarded the fifth section of the Eighth Circle of Hell, the Malebolge, in Dante's Inferno. The name translates to "Evil Claws", which is quite fitting for the claw-like Cie'th. Many of the individual Malebranche have been used elsewhere in the series, including Scarmiglione, Cagnazzo, Barbariccia, and Rubicante.
