S2·E24 The Great Gathering of Legendary Heroes! The Digimon All-Stars Showdown!!

The Old Clock Store Owner explains that to defeat Quartzmon one of the Digimon Hunters must prove him/herself stronger than all the others to obtain the Brave Snatcher, what remained of Bagramon, and infuse it with the powers of Taiki and the five Legendary Heroes from other time-space universes who saved their respective Digital Worlds. Before sending Tagiru, Ryouma and Noboru's teams, and a few other hunters to a separate dimension, the Old Clock Store Owner gives Akari and Zenjirou their own Xros Loaders so they and the reformed Xros Heart United Army can help keep Quartzmon at bay. Finding themselves fighting an army of Myotismon clones which emerged from Quartzmon, Xros Heart forms Shoutmon DX, XrosUpBallistamon with Deputymon, XrosUpDorulumon with PawnChessmon, XrosUpTsuwamon with SuperStarmon and XrosUpMervamon with Beelzemon. The fight takes turn for the worse when some of the Myotismon digivolve into MaloMyotismon and a group of VenomMyotismon.
