Tiger accepts a solo challenge from his brother, Gray Wolf. They will duel to the death at a location of Gray Wolf's choosing. Smelling a trap, Genki and the others tag along, but find themselves holding off Gray Wolf's Cabalos troops.
Tiger attempts to reason with his brother, but Gray Wolf is beyond arguing—and when it's apparent they're tied, he resorts to blinding him. Viciously smacking Tiger around, Gray Wolf goes in for the kill, but pauses when Genki blocks his way. Gray Wolf goes to kill Genki as well... and Tiger charges, impaling Gray Wolf with his horn.
Gray Wolf dies wishing they could go back to when they were pups, and Tiger mourns his brother... and meanwhile, Moo has found his original, draconic body.
This episode contains examples of:
- Aloof Big Brother: Tiger acted this way towards Gray Wolf in hopes of toughening him up. Unfortunately for both, it's Deconstructed: rather than making Gray stronger, he developed an inferiority complex and came to believe his big brother looked down on him. Moo was able to twist that to his own ends.
- Berserk Button:
- Tiger hits Gray's when he suggests that he hasn't changed at all since they were pups, still trying to scheme his way out of trouble.
- Happens again when Tiger takes his temporary blinding in stride, calmly remarking that he was the one who taught Gray how to pull off that technique in the first place.
- And again when Tiger asks him to take his life if he wishes, but spare the rest of the Searchers.Gray Wolf: [snarling] That mangy group is so important—?!
- Big Damn Heroes: Golem shoulder-checks the Cabalos away when they try to dogpile Tiger, heralding the arrival of the reset of the team.

- Come Alone: Gray Wolf's challenge orders Tiger to do so.

- Manipulative Bastard:
- It's revealed that Moo told Gray Wolf that Tiger intentionally let him take him away, trading his little brother for his own freedom.
- Gray Wolf makes a bid for this by claiming Tiger offered to join him, betraying the Searchers and handing them over. It's such a blatant lie that Genki and Mocchi immediately burst out laughing at the sheer audacity of it while the rest shrug it off.
- Might Makes Right: After recovering some food that was stolen from his brother, Tiger claims it for himself, invoking this. He later relents while claiming he wasn't really hungry.
- Not Brainwashed: Gray Wolf insists that he isn't, despite how his eyes and personality have changed.
