A couple of days after the rangers freed Kim from the spell, Zedd and Rita were sulking over their latest defeat and that the Machine Empire has a team of evil rangers They were trying to come up the next move.
The rangers, Billy, and Todd were at there usual hang out when Ernie was putting up fliers promoting a famous friend of his coming Saturday to sign autographs. Adam and Rocky were excited to find out that one of the best baseball players, of that time, was coming to Angel Grove. Neither Tommy, Kat, Billy, Todd or Tanya knew who this baseball player was. Kim only heard of him from her brother and dad, who are Oakland Athletics fans. Jason heard of the guy because some of his relatives talk about the A's when his family gets together.
"Hey Ernie, How do you know Mark McGwire?" Kim asked.
"We grew up together in the same neighborhood," he said.
"That's cool!" Jason and Kim said at the same time.
"My cousins are going to be so jealous when they find out that I get to meet Mark McGwire," Jason said.
"Well you know they can come meet him too, he will be here all weekend," Ernie said.
"They live in Sacramento, I doubt it that they will be able to make it," Jason said.
"So those pesky rangers are going to meet a famous baseball player," Zedd said.
"This gives me an excellent idea," Rita said.
"Does this idea involve a monster?' Zedd asked.
"Yes it does. We kidnap this baseball guy and turn him into a monster," she said.
"I was thinking the same thing," Rito said.
"Whatever you bag of bones of a brother," she said.
On Friday, while the rangers were in school, Mark McGwire showed up at the youth center to surprise his old friend.
"HEY MARK, YOUR ARE EARLY," Ernie said.
"Yea, well I am on my way up to my ex wife's to see my son. I don't get to see him very often during the season. Since I place my home game in Oakland and she doesn't live in the bay area," Mark said.
The two sat there talking for a while before Mark went on his way. Before he got in his car, Rito and Goldar attempted to capture him and take him back to Zedd and Rita. He gave them a tough battle but Goldar ended up winning the fight before they took him to see Zedd and Rita.
"Where the heck am I, and who the heck are you," Mark asked Rita and Zedd.
"Just two evil villains wanting to take over Earth," Rita said.
"I refuse to help you," he said.
"Ah but, you will have no choice in the matter," Zedd said pointing his staff at Mark turning him into a monster,
Mark now became a bulkier and taller version of himself with wooden baseball bats in each hand and baseball's that shoot laser beams for eyes. His red hair and goatee were bright red, he wore a red hat with a black Z on it, and he wore a black baseball jersey on with Zedd's name on the front and McMonster and the number 25 on the back and his cleats were red and black. The letters and numbers were red with grey outline. McMonster made his way back to Angel Grove wrecking havoc on the city until the rangers showed up.
As soon as school got out, the rangers teleported to the Power Chamber to learn about Zedd's latest creation.
"Rangers, behold the viewing globe. Zedd has unleash his latest monster, Mark McMonster, the baseball monster," Zordon said.
"Zedd has resulted to turning celebrities into monsters now?" Rocky asked.
"It appears so," Zordon said.
"It's time to take this monster down. IT'S MORPIN TIME!' Tommy said.
The rangers formed the Zeo Blaster and Jason used his Golden Power Staff on him. It worked until the monster grew. The rangers called for the Zeo Zords to form the Zeo Meagozord. Jason called for Pyramidas. The Megazord took on Mark McMonster The Megazord was doing pretty good against Mark McMonster as he was weakening.
"Sorry guys, sounds like you are on your own", Tommy said as Jason called on him for help which caused him to call for the Red Battlezord.
The rest of the rangers called on the Super Zeo Megazord. After a few shots from the Super Megazord Mark McGwire returned to normal.
"What happened? The last thing I remember is being on the moon, or some other planet being surrounded by some of the strangest looking creatures I have ever seen", he said.
"You were turned into a monster, but you should be ok now", Jason said.
Meanwhile King Mondo was making some adjustments to his team of rangers. He added zords and megazords to there arsenal.
The next day, Mark was at the youth center signing autographs when the rangers, Billy, and Todd, walked in. Kim came to get two autographs, one for her brother and one for her dad, as Jason went to get a picture with him. The others went along just to meet him.
"Hey, I know you, your Kimberly Hart who just won four gold medals in the Pan Goble Games", he said as Kim was surprised he knew who she is.
"Wow, I can not believe you know who I am. My brother and dad are just as big fans of the A's. These are my friends, Tommy, Jason, Rocky, Adam, Kat, Todd, Billy, and Tanya. We are also regular costumers of Ernie's", she said pointing to each one of them while she was shaking his hand with excitement.
When she calmed down, she asked him how he knew who she was. He told her his son told him about her as she was Marks ex wife's favorite at the games. Mark asked her if he could have a picture of her she said yes as Ernie got his camera to take it. Then, Jason asked Mark for his picture with him to show to his family at Thanksgiving and Christmas. Mark agreed.
