I think its totodile by far.
Chimchar
i suggest getting a totodile or cyndaquil
cindaquil because it evolves at an early level. =)
you should choose torchic because fire and fighting is good at most hoenn gyms
yes the best Pokemon is the fire type
You can't catch Treecko, because it's a starter pokemon. There's only one in the whole game and if you didn't choose it as your starter in Littleroot you can't catch it later.
All of the starter Pokemon are the best
Three of them is the best. But the onnly thing you should know is: Their Moves. It is important to teach them TM/HM Because If you choose the wrong TM/HM your Pokemon will eventually become weak.
Tepig
