Twilight was at the library as per usual, and was with Fluttershy when Rainbow Dash came in, carrying an injured Boss. "Fluttershy, here you are. We got an issue here." Rainbow Dash said.
"What happened to Boss?" Twilight asked as Fluttershy got out an animal first aid kit. "...Wait, you carry a first aid kit for animals around?" Twilight asked Fluttershy.
"It's in case I ever come across a very injured animal while I'm away from my cottage." Fluttershy said.
"...You know what, I'm not even going to bother." Rainbow Dash said.
"So what happened with Boss?" Twilight asked.
"Saw him get injured trying to help a foal dodge an incoming food vender's food cart. The foal was fine, but Boss got his paw pretty injured." Rainbow Dash said.
"Oh yeah, this is bad." Fluttershy said.
"Do you wanna tell his friends?" Rainbow Dash asked Twilight.
"Going to have to. But I doubt they'll be happy about this." Twilight said.
"I can't believe Boss is still on his hero complex." Hamtaro said.
"This really needs to stop." Bijou said.
"But what can we do? Boss has never really been like this before." Panda said.
"Yeah. And it's serious." Stan said.
"If only we knew someone who could help." Bijou said, dejected.
"We could ask Twilight and her friends." Hamtaro said.
"Wait, what did you just say?" Bijou asked.
"I said we could ask Twilight and her friends." Hamtaro repeated.
"Hamtaro, you're a genius!" Bijou kissed him on the cheek, causing Hamtaro to blush.
"You want us to help you solve Boss's issues?" Twilight asked. The Ham Hams had gathered the entire main six together.
"This hero complex of Boss's has gotten really out of hand." Panda said.
"We honestly don't know what to do." Pepper said.
"But, Hamtaro suggested asking you girls." Bijou said.
"Well, it's worth a try at least." Twilight said.
"I think I may have a couple of ideas myself." Rainbow Dash said.
"You do?!" Applejack exclaimed.
"Yeah. I do." Rainbow Dash said, smiling.
Over the course of the next few days, a mysterious masked pony known as "The Mysterious Mare Do Well" suddenly appeared and started saving a bunch of ponies that were often in trouble. This was making Boss really get upset over this, as he had a feeling that the Ham Hams were behind this.
"Seriously, I know I got injured during that foal saving thing, but what was I supposed to do there? Let it get hit?" Boss asked. "I just happened to be in the area when that occured. It could've easily been Rainbow Dash that could've saved that foal, and then all of you would be doing this Mare Do Well thing to her."
"What do you mean us?" Hamtaro asked.
"Oh don't even try to hide it Hamtaro. You and the other Ham Hams are behind the Mysterious Mare Do Well. Admit it, and I might avoid exposing the truth to the media." Boss said.
"Actually, it's not us." Panda said.
"Yeah right. Like you expect me to believe that." Boss said.
"Then believe what's behind you." Bijou pointed out.
"Huh?" Boss asked, turning around, only to see the Mysterious Mare Do Well in question. "...Okay so...your not the Ham Hams..." He said to the Mysterious Mare Do Well before he turned around. "And you're not The Mysterious Mare Do Well..." Boss said to the Ham Hams.
That's when five more of the same hero showed up. "I think he's learnt his lesson now." Hamtaro said.
That's when it was revealed that it was the Main Six; Rainbow Dash included. "Yeah, if you ask me, better to be safe than sorry." Rainbow Dash said. "I know a thing or two about ego. Trust me on that."
Boss had fainted. "...Why does part of me think he didn't learn the lesson we were hoping for?" Twilight said.
