All of the punks that surrounded Lin Fan's group were in the Platinum Realm.
That was considered quite powerful in the outer ring, it was just too bad they chose the wrong target to rob.
The reason why Lin Fan released Brainy was because Brainy was the best pet he had to deal with this situation.
In truth, since he had broken through, he rarely took out Brainy to fight anymore. The only times that he took out Brainy was to use its puppets to scout out an area or to find something.
Because of this lack of combat, Brainy now didn't have as many strong puppets that it could use.
While these Platinum Realm puppets wouldn't be much, Brainy would still have a use for them because of their appearances. They had the right appearances for certain uses, so Brainy didn't mind keeping them.
