The End Toby (Paranormal activity), Bloody Mary (Also Paranormal Activity), and Slenderman vs. the Ghostbusters.
MechaGodzilla vs. Megatron? Hmmm... this is going to be a difficult decisi--ALL HAIL MEGATRON The Last Airbender (M. Night Shyamalan movie) vs. Dragon Ball Evolution in a contest to see which is a worse film adaptation of their respective source material.
Dragon Ball Evolution, but only slightly Avatar the last Airbender vs. Dragon Ball What cartoon was better.
EXPELLIARMUS!!!!!!!!! (That means Harry.) Chong Li (Bloodsport) Vs. Tong Po (Kickboxer) (Please don't say neither.)
I haven't seen either movie, but based on what I could find about the actors and characters, I'm going to say Chong Li. Liu Kang (Mortal Kombat) vs. Ryu (Street Fighter)
Even though I like both Mortal Kombat and Street Fighter I've always liked Mortal Kombat more so Liu Kang MLP Cerberus vs. Greek Mythology Cerberus.
The Cerberus of Greek mythology is favorite Hellhound of Hades and the son of Typhon and Echidna. The Cerberus of MLP is an overgrown puppy with extra heads. I'm going to say that the original would win this fight. Tirek with Alicorn magic vs. Cthulhu
Discord. God of Chaos, remember? Richard Petty vs. Dale Earnhardt Sr. in a twenty lap race at Daytona.
Darrell Waltrip........ eesh. Adrian V. or Batman? (Best to not answer if you don't know my character Adrian Vogelcheuche. You can check it out on the finished Fatherland RP in the RP forums.)
