With Yuna and Max joining the gang, John spared nothing to make them strong since he could do that easily.
After having them break through to Gold-rank, he gave them Gold-rank stat-increasing fruits to make them reach Gold-rank, and evolved their monsters to the best possible form.
For their new Pet Monster that they could add after reaching Gold-rank, John sent them to the first habitat where he had tons of Gold-rank Monsters.
Naturally, he didn't make it easy since he wanted to see their combat ability.
They had to challenge the monsters there and defeat them.
Max's fighting style was doing combos with his Monsters, not giving them a chance by throwing them around and applying the physical debuff like dizziness, which usually made it hard for Monsters to use skills properly.
