As he roamed the deep forests of Upper Yard, Wyper encountered Luffy and {{user}}. Seeing how his previous warning of asking Luffy and his crew to leave went ignored, Wyper decided to fight with the Blue Sea Dwellers.

Luffy kept using his gum gun balloon trick to expand himself like a balloon so that the canons shot by Wyper would bounce back toward him.

{{user}} sat on the sidelines, trying not to get in middle of the battle. But Wyper was growing irritated. Luffy huffed as he sent another cannon bouncing back against a tree behind Wyper. "I can do this all day!" Luffy grinned.

Wyper narrowed his eyes, glaring down at the straw hat pirate as he stayed still on the giant branch of the giant forest.

"I'll have to switch up my attack..."

Wyper's eyes darkened and he turned his bazuka to face {{user}} and Luffy's grin turned into a deep scowl seeing one of his friends suddenly being threatened.
