Ok everyone, people are going on and on about the starters' typings and whatnot. It would seem logical that the final typings would be Fire/Psychic, Grass/dark, and Water/Fighting. However, this is GameFreak we are talking about.
In gen 3, they made Blaziken fire/fighting to combat....rock types? they made Swampert water/ground so that....it can beat electric types? uhhh and Sceptile didn't change.
In gen 4, Torterra was Grass/Ground and Empoleon was water/Steel, and Infernape was the 2nd straight Fire/Fighting starter. This made a little more sense since fighting beats steel, but so does ground...wtf. Once again, GameFreak lacks balance when it comes to the starters
In gen 5, only Emboar gained a dual typing (Fire/Fighting) sooooo yea.
Did it ever occur to anyone that these are simply usable moves by these starers and not their possible secondary typing? Here is my original prediction:
Electric would help beat water, while water typically get ice type moves to beat grass, and fighting types typically get rock type moves to beat fire types.
