With Kimo snug and captured inside Mercury's new Master Ball diaper, he told the brothers he was gonna test it on other pokemon as a field test.
Kimo didn't put up a fight inside the diaper as Mercury waddled around and found a Charizard nearby, wanting to test it on a bigger pokemon he called for the charizard. When the Charizard turned around, Mercury already pressed the button on his diaper and a beam shot out and it started capturing the helpless Charizard. Mercury watched as the Charizard started sinking into the diaper as Mercury watched, and even feeling the diaper get thicker.

Despite the attacks, the diaper didn't get damaged at all and now Kimo had some company inside the diaper.

Mercury belongs to Me
Pokemon belong to Game Freak
