The Internet is filled with crossovers about MLP and TF2: Drawings, fanfics, videos... This is just another one.
I wanted to show how the mane six would work together with the class they're always paired (Rainbow Dash with Scout, Pinkie Pie with Pyro, Applejack with Engineer, Rarity with Spy, Fluttershy with Medic, Twilight Sparkle with Sniper...) by adding weapons and hats with skins and mods of My Little Pony, along with showing how the ponies would help. In this video the only rule is that the ponies are with the RED team, and that the BLU team hates them because... Well, because they hate multi color talking ponies (Choose your own reasons. I'm not here for that).
There's some mistakes and weird movements, but since it was very hard to finish this video because of a lot of problems with Source Film Maker, I don't care. I accept constructive criticism about things that I could improve.
My Little Pony belongs to Hasbro. Team Fortress 2 and Source Film Maker belongs to Valve. The models of MLP belong to whoever made them in the first place. The skins were downloaded from this place: http://www.mlptf2mods.com/
