As the teamup with the strawhat pirate, Tony Tony Chopper, and the Mane 6 come to a close in defeating the Ram Warlock Grogar. Seeing his plans falling apart, he summon enough power to shoot at an unguarded Fluttershy in which Chopper used his Heavy Point body to shield her unaware that the reindeer was the true target. The evil overlord used his endgame to dart Chopper with an overdose of his Rubble Ball formula and allow his Monster from to rampage and crush Fluttershy underneath. The other ponies were horridly stunned as Chopper grew into an enormous behemoth with his howl echoes throughout the caverns of Grogar’s fortress. Grogar’s malicious grin however was short-lived as Chopper’s howl turns into laughter as he reveals Fluttershy is his palm, unharmed.
 
“Fluttershy!” Twilight and the other exclaimed.
 
“Surprised, Old Goat?” Chopper inquired Grogar.
 
“Impossible! How? How is it possible you have control?” Grogar demanded.
 
“All this time, you had try to take anything from me and make me as heartless as you, Grogar. All of my resentment and pain from my past was bottled up in this form. Thanks to Fluttershy, I had learned to let that pain go and become stronger. For her, for Luffy and my all friends!” Chopper confidently smiled.
 
“I will never admit defeat by an outcast runt like you!” Grogar yelled as he launched himself in his own version of Chopper’s old jump/horn point to attack.
 
“Grogar, you’d used my formula, my own forms and set most of Ponyville against me but now, you are done, your plans all ruined and your time as the Hito-Hito fruit user has long since past…” Chopper calmly responded as he lifted his left arm.
 
“CARVING HOOF: PALM!!!” The Monster Chopper swatted down Grogar effortlessly to the ground.
 
“…and as far as I am concerned, I have long since surpassed you…”
