The 2005 General Grievous was the monster cyborg General of the Confederacy of Independent Systems. He was trained under Count Dooku and soon killed various Jedi for no known reason. He was genoicidal across the galaxy and became the greatest villains.

If the 2005 ever met the heroic 2008 GG, the 2005 would be a match for the younger GG 2008 and kill him saying: "Your lightsabers will make a fine addition to my collection, 2008!"
