A couple of weeks after the fire, Neckrox was training with Krennick and Rusty.
"I can't believe how fast you are," said Krennick as he chased after Neckrox who was dodging each of his swings.
"Then let's see what he can do against my new body," said Rusty, whose body had been switched with a slicker model.
"Please," said Neckrox as he dodged all of Rusty's punches.
"I'm already at thirty percent of my max speed," said Rusty.
"Funny, I only figured myself at twenty percent," said Neckrox before punching Rusty in the gut, sending him flying.
"What the?!" asked Krennick as he jumped out of Rusty's path, letting his crash into a far off wall that shattered on impact.
"Your turn bro," said Neckrox as he easily closed the gap before kneeing Krennick in the gut, causing him to collapse to the floor while holding his stomach.
"I see that you have grown stronger," said Zephyr as she entered the room.
"Yeah, and I'm sorry if I hurt you guys," said Neckrox as he helped Krennick up.
"You dented my suit, but everything else is fine," said Rusty.
"I think you broke a few ribs, I'll need Doc to fix them," Krennick as he held his stomach.
"Sorry about that, I need to manage my strength more, especially before I can go up against human criminals," said Neckrox as he supported him. Later, the two were in Doc's lab.
"You'll need to stay in this regeneration chamber for a few hours to get those ribs healed faster," said Dock as Krennick sat in a pod.
"Alright," said Krennick before a lid closed over his head.
"I can't believe I hurt him this bad," said Neckrox as he sat on a chair nearby.
"You're still young, it makes sense that you don't know your full strength yet, and especially so if you haven't even trained till recently," said Doc.
"But how can I be a hero if I hurt someone just by training?" asked Neckrox with a worried expression.
"Why don't you take a few days and just relax, then try training by yourself for a while,"said Doc.
"Okay," said Neckrox before getting up to leave the room.
