Shoutmon X4

Shoutmon X4 is a Composition Digimon. It is a miraculous form called the "Victory Mode" (ヴィクトリー形態), born from Shoutmon, Ballistamon, Dorulumon, and the Starmons' powerful desire to gain absolute victory. Its raison d'être is nothing but enforcing this conviction. That power is tremendous, and it isn't a mistake to count it as one of the strongest Digimon. Its main specialty is in battling on the ground, and it wields the "Star Sword DX".
