On top of the whole fact that it's Screw Attack recognizing ponies are more awesome then Transformers, they feature a lot of fan content in there like:
-NACP's Sonic Ranboom
-Infinity Dash's Fluttershy's Fashion Show
-I think I hear the metal version of For the New Lunar Republic at one point, but that may just be a guitar riff that sounds kinda similar
-All the Rainbow Dash sprites are from Desktop Ponies
-Voice acting from Friends of Dream Valley
-Tons of fanart
-etc. etc.
