touch and her Friends Rarity, Fluttershy, Spike, Pinkie Pie, and
cidre fort, applejack had escaped to avoid transformed par
Grandfather.Twilight Sparkle realized that in order to defeat Grandfather, she had to rely on the help of Luna and Celestia to do so.Later with Celestia, both her and Twilight arrived at the house of Luna to warn Luna of Grandfather's arrival.After some careful convicing, Luna and Celestia went out to fight Grandfather.I AM VERY VERY VERY VERY ANGRY!!!!snapped Luna at Grandfather, surprising the dark black villain, however he was not intimidated par her temper.After this, she went back inside, leaving Celestia to fight Grandfather on her own.However, like Luna and Twilight, she too was immune to being infected par Grandfather's touch.Do toi really think toi can defeat me?asked Grandfather.At that very moment, Twilight was setting a course for a moonbase to crash directly into Grandfather, but not before fighting off some senior citi zombified versions of Spike, Fluttershy, arc en ciel Dash, Pinkie Pie, Rarity, and Applejack.Before they could attack Twilight, a dark blue blast of magic made them back up slowly.Luna!said a surprised Twilight.You don't think I'd let toi fight these guys par yourself, did you?asked Luna.Dost thou want a piece of me?asked Luna, challenging them to a six on one fight.Pinkie Pie and Fluttershy charged from two different angles, however Luna tricked them into running into each other.Rarity was ready to jump at Luna, only to be blasted away par Luna.Applejack, arc en ciel Dash, and Spike had seen enough, but they too got knocked out when they all ran into each other.After they saw how powerful Luna was when facing six opponents, they retreated, allowing Twilight to defeat Grandfather par crushing with the moonbase.On earth, Celestia's hooves were getting wrinkly due to her ongoing fight with Grandfather.I just hope we can make it.said Twilight as the moonbase sped towards earth.Suddenly before he knew what was going on, the giant moonbase crushed Grandfather.Did we defeat him?asked Twilight.Nope!said Grandfather emerging from the rubble without a scratch.Twilight, Celestia, are thou ready to defeat Grandfather?asked Luna.Yes!they replied at the same time.Good.Then let's get to work finishing something I never finished.said Luna as all three of them used their magic to defeat the powerful dark villain, who although he was all powerful wasn't feeling so powerful when he got overpowered par the combined efforts of Celestia, Luna, and Twilight's magic.
