Dog Brother #1's debut in the tournament was less than spectacular. After Bride of Nine Spiders unleashed a swarm of spiders on him, Dog Brother #1 took the fight to her, and the two were tossed from the Heart of Heaven for unknown arenas. What took place after that was mystery to all, but once his pack began to howl, all in attendance knew that Dog Brother #1 had been defeated. Dog Brother #1's next appearance at the tournament was to announce the contest between Fat Cobra and the Prince of Orphans. However, the Prince wanted to face Davos instead. At that night’s festivities, Dog Brother #1 and Iron Fist asked the Prince of Orphans to sit with them at their table, and he had to be restrained by Iron Fist when the Prince ignored them. However, it wasn’t long before the Prince of Orphans returned and asked to sit with the other Immortal Weapons just as Dog Brother #1 was spinning a tale of a past conquest. The Prince asked the prankster-assassin to stand by his side as a group of terrorists known as Hydra was about to demolish the fabled city of K'un-Lun. Dog Brother #1, always ready for a fight, may have decided to aid the Prince anyway, but the added threat to his city definitely made him an ally. After the conflict left Hydra beaten, Dog Brother #1 decided to stay on Earth with the rest of the combatants of the other seven cities.

Dog Brother #1 was on hand when the villain, Zhou Cheng, came to kill Iron Fist. His wolf pack assisted in rescuing the children that were being used as hostages in order to lure Rand out in the open, and he was there when a bomb exploded in Cheng's apartment, almost killing him and his teammates. Dog Brother #1 also went on the journey with the Immortal Weapons to the Eighth Capital City of Heaven.
