GAK IS BACK EVERYPONYYYYYYYYYYYYYYYYY!!!
For anyone who watched the season 3 premiere live (or recorded it), you know who the TRUE villain was... and it wasn't that namby pamby pony king! It was GAKKKKKKK!
But yeah! Instead of crystals getting on Shining Armor's horn and fudging up his magic, it should have been GAAAAKKK! In fact, get rid of the Crystal Ponies and replace them with GAK PONIESSS!
Just imagine it: Shining Armor throwing Cadence like a javelin only to have her miss Spike and the heart... BUT WAIT! Cadence bounces off of a GAK building and off of the GAK castle, saving the day! Woo hoo! GAK makes everything totally RADIGAK AND GAK-XTREME!
