As the four other heroes watched in horror Betty started to grow larger before their very eyes. Her costume strained to cover her body which was expanding with powerful muscles as well as bigger tits.

When Betty had finished growing her stood seven feet tall, her outfit was little more than tatters on her body which was covered in thick powerful muscles. She flexed her huge arms the biceps bigger around than their heads.

"I'll give you each a free shot," Betty said. "Better make it count."

Pureheart and Captain Hero both stepped up simultaneously. They planned to knock Betty away so they could deal with Cheryl. However their punches had no effect, it was as if they were hitting a brickwall. Betty stood there as though she was waiting for something to happen.

"Sorry was that your best?" Betty asked.

Pureheart and Captain Hero had both held back, Betty was still their friend and they didn't want to hurt her. But now that had cost them. Betty wasn't their friend anymore and she grabbed each of them by the head in her huge hands and smashed their heads together before flinging them aside like rag dolls.

Miss Vanity stepped forward and used her Sonic Scream on Betty. Betty just stood their smiling even though she should have been holding her ears in pain from the high pitched noise. Betty then stepped forward and with one massive fist hit Miss Vanity with a huge uppercut sending her flying into the sky and out of sight.

"I've always wanted to do that," Betty said with satisfaction.

That left only Evilheart.

"Hey I know when to give up on a losing battle," Evilheart said holding up his hands in surrender. "I'll happily join you."

"Oh well isn't that nice," Cheryl said.

"I can help you defeat Pureheart and the rest of those losers," Evilheart said.

"If I had wanted you to join me I would have chosen you," Cheryl said. "But I picked Betty here."

Cheryl then nodded at Betty and Betty grabbed Evilheart by the back of his head and slammed him face first into the ground, his teeth shattering and pieces flying everywhere. She then proceeded to stomp on his head as hard as she could until his head was little more than paste.

"This one is dead how can I serve you my Goddess?" Betty asked kneeling before Cheryl.

Cheryl smiled as she considered what to do next.
