The attack of the cyberponys

"WOOO HOOO!"yelled derpy as she held on to the TARDIS."DERPY GET BACK INSIDE!"yelled Dr.whooves. Derpy was currently holding on to the top of the TARDIS as they flew threw space and that always made Dr.whooves angry because even though she was protected she would always get injured from the fact that she always slammed her body on the door when she began to lose her grip. Derpy flew back inside as fast as she could."that was fun!"she said as she fell on the floor of the TARDIS. Dr.Wooves chuckled and helped her up. The TARDIS landed."were are we now?"asked derpy."i dont know"Dr.whooves replied."i think were back at ponyville because the tardis isnt saying were we are and that usually means were in ponyville."."YAYYYYY!"screamed derpy and she dashed through the tardis doors."DERPY WAIT!"Dr.whooves yelled. When he got out of the tardis they were in a small hut with lots of creepy decorations. There were tiki masks and candels and on the ground a zebra cowering in the corner."oh hi zecora!"derpy said cheerfully."ah its you in my room.for a second i was scared and tried to keep out of veiw."zecora said getting off the floor."hi im the doctor!"said Dr.whooves looking around the room."well hello doctor welcome to my hut,but howd you get here in a cloud of dust?" zecora was curious."magic.okay now were are we." said Dr.whooves starting to take intrest in the room."you are in the everfree forest on the outside of ponyville.before you go i must warn you its dangerous there.". Dr.whooves and derpy raised there eyebrows."what kind of danger?"he and derpy asked curiousily."there is silver ponies all over ponyville.the ponies are going down in numbers and the silver ones,there are more and more.im afraid if someyone dosent stop them soon all the ponies will be consumed." That was enough to send derpy and the doctor galloping back to pony ville.zecora ran after them.when they got to ponyville derpy and Dr.whooves stoped dead in there tracks. There were cyberponies everywere.they were chasing the few regular ponies that were left. Derpy looked in horror as she saw one with lyras cutie mark on the flank. It came towards them."Derpy you have the sonic screwdriver,right?"asked Dr.whooves."y-es"replied derpy pointed the screwdriver at the approching pony.zecora backed up.the cyberpony lunged and, pulled off her mask."LYRA!"screamed all three ponies with joy."yeah its me!"she said happily."but how did you..what!"asked Dr.whooves completly confused for once."rarity sewed some armor for us once we discovered what was happening.thank celstia i found that iron mine."lyra said smiling."well that is wonderful news but how many others are as lucky as you?"zecora asked concerned for the other ponies."twilight rarity applejack and apple bloom."she replied."wait then that means the other ponies are in danger!"lyra stopped smiling and ran to fluttershys house,zecora ran to sugercube corner and derpy and doctor whooves went to cloudsdale.
