Typhlosion is the best starter (a walk through gen 2) (long)

[QuMus]

Starting out as a cyndaquil, It learns smokescreen 1 level after you get it, making leveling up easy as pie. Getting to Mr. Pokémon's house is a simple matter of smokescreen and tackle. Once your cyndaquil evolves at an earlier-than-normal level 14 you're likely about to challenge the first gym. Birds plus fire equals fried chicken. Bam, easy, done. Once you get to azalea town, your quilava's power is increased further by the charcoal item. Slowpoke well means team rocket means poison types and normal types means TRASH. The gym is kindling to your walking campfire of death. Going into the ilex forest, you are challenged by your rival. His gastly's hypnosis poses a small threat, but that threat is destroyed by smokescreen. As long as your rival's starter does not do too much damage, you should be fine. Moving on through the ilex forest, you very much should level up your quilava, for soon-evident reasons. Goldenrod city gym is easy.
Well...
MILTANK
One of the best-known threats of the second generation, this level 19 beast can lead to many losses. Rollout can destroy quilava easily, but not with the right strategy. Spamming smokescreen and super potions keeps your pokemon alive, and rollout locks away milk drink and stomp temporarily. If you find yourself unable to emerge from the goldenrod city gym victorius, grind up to a higher level in the conveniently-located Ilex forest.

That's all for now, I will update it later if I find the time. School makes me busy.
