Chapter 297 - 297: The Crow’s Mouth
Judging by this person's appearance, he's probably not one of the elite Officers' subordinates.
Otherwise, Cain wouldn't have had such an easy fight against him.
Although Cain didn't use his full strength in the previous battle, he didn't even mention that the Haunter hidden in the shadows didn't intervene.
Part of the reason is that he couldn't be certain the opponent was alone, so he needed to maintain some response capability. Another reason is that the opponent's two Pokémon didn't pose a significant threat to him.
Although the opponent's Pokémon had considerable power, they didn't pressure Cain too much.
If he had really been willing to risk taking damage, Slowpoke could have defeated the opponent on its own.
The reason he didn't pursue the opponent was that he couldn't be sure if he was alone. In this unknown forest, although the opponent appeared suddenly and it's unlikely he had companions, popular wisdom says not to pursue a cornered enemy.
Cain had Slowpoke and Miltank work together to defeat Machoke and then took the Poké Ball Murkrow had delivered, trapping the still-furious Primeape who was trying to attack.
This high-quality Primeape, if evaluated by its value alone, could be worth close to a million Pokédollars.
Furthermore, the opponent had trained Primeape quite well, which could further increase its value.
Cain had Murkrow and Slowpoke clean up the scene and then released a Grimer to absorb the remains of Machoke.
