When Shoutmon hears MetalGreymon's melody still responding, he allows himself to be DigiXrossed by NeoVamdemon, along with Lopmon, both of them try to convince MetalGreymon not to give up. Lopmon then summons all the captive Lopmon to form as white Lopmon which then enables Shoutmon and MetalGreymon to digivolving into OmegaShoutmon and ZeekGreymon. However, they are still in the disadvantages stage until Lopmon sacrifices himself to give Taiki and Kiriha the ability to perform a Double Xros, allowing OmegaShoutmon and ZeekGreymon to become Shoutmon DX.
