Ben, Gwen, and Grandpa Max we're walking through Washington newest Mega Mart to gather some food. When Ben saw that Sumo Slammer cereal had Sumo Slammer cards in them and if he was lucky he could get the legendary gold card. "Grandpa, can I get some Sumo Slammer cereal?" Ben asked.
"Sorry Ben but people who do dangerous stunts don't get rewards." Grandpa responded as Ben smile turned to a frown, "And beside it's bad for you. Maybe you could pick out a more healthier cieral."
"No thank Grandpa." Ben said with is a fake smile.
"Grandpa! Grandpa!" Gwen screamed as she rush over to them "Can I get the latest Grimoire Girls book."
"Sure thing Gwen," Grandpa Max said.
"Why does she get something?" Ben asked with anger.
"Maybe because I saved people from a burning building." Gwen said arrogantly.
"Now, Gwen that's not why your getting the book." said Grandpa Max.
"Then why Grandpa?" Ben asked. His question was met with silence form his Grandfather. "So she's right she saves people from a burning building and gets a rewarded. I stop robbers form stealing people's money from a bank a can't even get a box of cereal. It's just not fair." Ben said whale he stormed off into the cereal aisle.
Ben stood in the cereal aisle his anger welling up inside he looked at one of the boxes of Sumo Slammer cereal then all of a sudden the boxes of cereal began to explode open. Miss Perfect decided to show up and began to scream her head off.
"Grandpa! Bens trashing the cereal aisle!" Gwen screamed at the top of her lungs.
Ben closed his eyes and wish he could vanish before Grandpa got there. When he opened his eyes he was standing in a different aisle. "How did I...?" Ben said to himself. He could hear Grandpa in the next aisle try to defend Gwen from to a employee the must have showed up from all of her yelling.
"Look what your granddaughter did." said the employee.
"I sure my grandson would be happy to pay for the damages." He heard his Grandpa say turning the blame on to him and off of Miss Perfect. Ben could not believe it Gwen made him angry and loss control and he was the one paying for it.
Ben left the aisle an continued to explore the store and try to clear his head. He was in the electronics aisle when all of a sudden a giant mutant frog with a guy with a weird hat came crashing through the wall. Then the Mega Marts two security gardens showed up looking shocked and afraid.
The strange man grabbed the component he needed and climbed back on his frog and hopped towards the pet aisle.
Ben wanted to prove to his Grandpa that he could be as much of a hero as Gwen, but first a change of clothes. He rush over to the boys clothing department and grabbed a black leather hoodie, some black skinny jeans and a green handkerchief to hide his identity.
Ben rushed over to the pet aisle just in time to watch Grey Matter get her but whooped. Gwen was try spell after spell but nothing seemed to be happening apparently she couldn't use her anodite powers in the Omnitrix alien forms. Before Gwen could get squashed by the giant frog Ben sent of a mana blast.
Knocking off the strange man, he said "I am Dr. Animo and a child will not stop me." then his wired hat let out a beam of light cause a hamster and bird to morph into monsters.
The bird and Dr. Animo flew off with the frog on their heels whale the monsters hamster tried to make a snack out of Grey Matter and Grandpa. Grandpa was holding Gwen and running for their lives that's when Ben decided to show himself. When the giant hamster was between two aisles Ben created mana beam to grab one off the shelves and pulled. Like dominos the fell right on top of the hamster monster trapping it.
"Thank you mysterious boy how can I ever repay you." said the store manager.
"Well..." Ben began spotting a display of the full collection of Sumo Slammer Cards. That when Grandpa Max grabbed Ben and started to leave the store. "Grandpa I was going to score the full Sumo Slammer card set." Ben said.
"The only thing your scoring is a grounding." said a very angry Max.
