Iron Arm was most angered at being hit into the ground by Cole and then his blast had somehow charged Amber's power and now he had been smashed into the ground and sent into a mountain. these organics were pushing him to not hold back as much as he was doing up until now. when Iron Arm heard Amber laugh crazily and fire a powerful blast of energy, he shoot his power level up to 180,000 and formed a protective energy field around his body. 

"Hyper Dash!" and with those words, Iron Arm took off at speeds faster than what any of the Z-fighters could see and flew right through the beam of energy, barely feeling a thing and he put an insane amount of strength into his metal fist and landed an insanely powerful punch to Amber's gut. the force of the impact caused the air to blow away and sent the girl flying for a huge distance. he didn't stop there, he took off after her and moved ahead of Amber in her flight and kneed her high into the air. he then flew after her and began to knock her around in the air with immensely powerful punches at almost unimaginable speeds. he finally uppercut her higher into the air and then appeared above and charged up energy into his fist. Iron Arm slammed both of his fists into her chest and sent straight back down to earth, causing the ground around her impact to crack and shake violently. 

Iron Arm then charged up a powerful blast of energy and shouted "Ultra Cannon!"

he fired a massive of energy at the crater he had slammed Amber into and when it hit, the entire area would be blown away and turned to ash.
