I don't own cells at work and RWBY

Chapter 5

Inside the human body, roughly 37.2 trillions cells work energetically all days. 24 hours and 365 days. They are all working very hard to keep the body healthy.We are again in the area were the immune cells and virus fighting each other but our favorite red blood cell; Ruby deliver something to them making the immune cells stop as they watched the ball spilt in half and inside the ball is a ginger-haired girl with a bow.

"Initiate PENNY" the girl said.

"I think her name is Penny" Ruby said.

"Utilizing weapon" Penny said.

Penny transform her right arm to a gatling gun and he left arm turn to a plasma rifle, in here back turn to a missile launcher. The immune cell and Ruby stare blankly to Penny.

"Ehhh!" they said.

"Firing now" Penny said.

Their eyes got wide and scream in fear.

"AAAAAHHHHH!!!" they said.

Penny start firing bullets, lasers and missile infront on her, the immune cell and Ruby quickly dodge Penny's attack but the virus are unlucky killing them in the process. Jaune in other hand revert back to his small body running and screaming like a little girl.

"AAAHHH" Jaune scream.

"Come back here you" Yang shout while dodging.

Penny then walk to Velvet's office, Velvet is surprise to see Penny but she fire her making Velvet run away out of her office.

"I'm sorry" Velvet said crying comically.

Velvet keep running until she bump someone, none other than Coco.

"YOU! Thanks to you we almost drown to our death" Coco said.

"It's your fault, you use to much antibiotic" Velvet said.

Both of then start to argue, they did not notice Penny was beside them.

"Lifeform detected" Penny said.

Both of them see Penny ready to fire. They start running far away to Penny. The immune cells see Coco and Velvet running to them and they see Penny chasing them they start running away to them. Above to the same building we're the macrophages and May standing, they watching the scene where Penny shooting the cells.

"Are you sure they are okay miss Glynda" May said.

"Ara-ara you must not watch violence young one" Glynda said.

"Sorry miss Glynda" May said.

"*giggled* Don't worry I'm not mad" Glynda said while hugging her.

Back to the cells who being chase by Penny, everyone is now panicking and dodging. Oobleck mumbling while running that Ruby is the plague. Then Karma strike to Oobleck a lone missile hit him blasting off out in the sky.

"Karma is a b*" Oobleck shout flying out of nowhere.

Penny suddenly stop making the cells stop too.

"Is that thing stop" Yang ask.

"I don't know" Weiss answered.

"I hope so" Ruby said.

"I never run this long before" Velvet said.

"That what you get setting around Fat cell" Coco said.

"WHAT DID YOU SAY!!!" Velvet shout.

Both of them start arguing again, the other cell sweatdropped to the scene. Yang then poke Penny's head then a she suddenly speak.

"Self-destruct sequence activate in T-minus 10 second" Penny said.

"AAAAAHHHHH!!!" they shout again.

Both the cells take cover but the other two cell that argue did hear the warning, when the timer go to zero it exploded making the area destroyed. When the explode stop they see the surrounding was completely destroyed but the funny thing they see is that Coco and Velvet cover in black ash head to toe, both of them widen their eyes. The immune cells and Ruby laughing out loud of the scene that they never forget. In the office of Ironwood, Winter still working in her laptop suddenly the rooftop burst open making Winter stop working and investigate what is it. Ironwood running to his office.

"Winter what is happening in here" Ironwood ask.

"I think I know sir" Winter said pointing something (or someone).

They see Oobleck face plant in the concrete floor, both Ironwood and Winter sweatdropped to see the Memory cell.

"*sigh* Winter bring the cleanup crew" Ironwood order.

"Yes sir" Winter said.
