Venusaur is the first starter line ever printed, and the only one that turns into a plant: four weaknesses, five resistances, and 100 in both special stats.

Abilities: Overgrow · Chlorophyll (hidden) · Evolution stage: final
Both columns follow the standard 18-type grid on the Pokemon Type Chart has them.

Water Electric Grass 0.25x Fighting Fairy
Mewtwo and Squirtle bracket the other end of the Kanto dex, one legendary and one starter line.
The original Grass starter
Number 3 is the last stage of the Bulbasaur line and one of the three Kanto starters, which makes it the first Grass-type starter in the series. The typing is Grass and Poison, the abilities are Overgrow and Chlorophyll, and it arrives from an Ivysaur with nothing after it.
The design carries the theme: a flower that grows on the back and opens in sunlight. It is the only starter line that becomes part plant rather than staying purely animal, which is the reason it stands out in a trio of otherwise straightforward elemental designs.
Four types do extra damage: Fire, Ice, Flying and Psychic. Five come back reduced: Water, Electric, Grass, Fighting and Fairy. There is no immunity on either side of the chart.
That is a lot of exposure, and two of the four weaknesses are common attacking types. Psychic is the odd one out and the most dangerous, because it is rarely the move an opponent uses casually, and it lands on a Pokemon that has no way to answer it.
The spread is 80 HP, 82 Attack, 83 Defense, 100 Special Attack, 100 Special Defense and 80 Speed. Both special columns reach triple digits, which makes it a mixed attacker that leans special and can still absorb a special hit.
The physical side is thinner and the speed is average. Venusaur is not fast, not especially bulky on the physical side, and not a Pokemon that wins a damage race. It works by staying in fights longer than it should be able to and grinding out the result. Nothing about the spread is a wasted investment, and nothing about it is going to surprise an opponent either.
Overgrow boosts Grass-type moves once health drops below a third, which means the Pokemon becomes more dangerous exactly as it looks finished. It is the standard ability and it rewards playing Venusaur on the edge rather than switching out at the first sign of trouble.
Chlorophyll doubles its Speed while the sun is out, taking an average 80 up to something that moves before almost everything. It needs a sun setter on the team to be worth anything, but on a sun squad it changes the Pokemon completely.
Bulbasaur becomes Ivysaur at 16 and Ivysaur becomes Venusaur at 32. No stones, no trades and no friendship counters, which makes it the most predictable of the three Kanto starter lines.
The middle stage is short by the standards of the era, so a run that picks Bulbasaur gets to the final form earlier than the Charmander or Squirtle paths do. For a challenge run with a level cap, that timing is often worth more than the stat differences between the three.
Plan the six in the Pokemon Team Picker, set run rules in the Nuzlocke Team Builder when a faint ends the attempt, and use the Random Pokemon Picker to fill any remaining slot.
The numbers live on two other pages: the Pokemon Nature Chart for the nature and the Pokemon IV Calculator for the spread, with the Pokemon Wheel Spinner for choices that need neither.
For everything else there is Random Shiny Pokemon Generator and Pokemon Shiny Odds on the collection side, plus the Random Mega Pokemon Generator and Who's That Pokemon.
Venusaur does not want to be brought in blind. Fire, Ice, Flying and Psychic are all common enough that a careless switch ends badly, and the usual entry point is a Water, Electric or Grass move that it can completely ignore.
Once it is on the field it can stay there. 100 Special Defense on 80 HP lets it sit in front of special attackers, and Overgrow means the opponent has to finish it quickly or deal with a boosted Grass move.
The stats have been outclassed many times since Generation 1, and the four weaknesses have not gone away. What keeps Venusaur relevant is the role: a Grass type that can take special hits and a Poison type that ignores poison status, on a body that grinds rather than races.
As the first starter in the series it also carries a certain expectation. A trainer who picks it is choosing the option that does not have an obvious plan, just a lot of patience and a stat line that rewards it. That has been true since the very first cartridge, and nothing in the later games has really changed it.
Venusaur has a mega evolution that adds Thick Fat, halving the damage from Fire and Ice moves. Two of its four weaknesses are cut in half on the spot, which turns a fragile defensive profile into a solid one.
That is the single biggest change available to this Pokemon, and it is the reason the older write-ups on Venusaur often read as if it were a wall. In its standard form it is a patient attacker; with the mega in play it becomes something considerably harder to move.
FAQ
Venusaur is a Grass and Poison type. That gives it four weaknesses, five resistances and no immunities at all, which is one of the busier charts in the dex.
Fire, Ice, Flying and Psychic all hit it for double damage. Water, Electric, Grass, Fighting and Fairy come back reduced, and nothing is immune in either direction.
Bulbasaur becomes Ivysaur at level 16, and Ivysaur becomes Venusaur at level 32. There is no item and no trade in the line, just the two level requirements.
Overgrow is the standard ability and Chlorophyll is the hidden one. Overgrow boosts Grass moves once health drops below a third, while Chlorophyll doubles its Speed while the sun is shining.
Three stages in a straight line: Bulbasaur, Ivysaur, Venusaur. Nothing evolves out of Venusaur, so the chart stops at the final form.
Grinding out long fights. 100 Special Attack and 100 Special Defense on 80 HP let it trade with special attackers, and Overgrow makes it more dangerous as the fight goes on rather than less.
