Is Treecko Good in Ruby & Sapphire Playthrough?

The speedy Grass starter. Treecko handles Roxanne and gets through Brawly with Speed. The mid-game stretch against Flannery and Norman is where Grass coverage doesn't help. Sceptile at 36 is one of the fastest fully evolved starters. Pick Treecko if you want Roxanne handled and Wallace trivial.

Shiny Odds

Both methods here share the same odds, about 1 in 8,192 on each try. Pick whichever fits how you play.

Step 1 · Encounter Method2 in Ruby & Sapphire

Soft Reset: Save in front of a static, gift, or legendary encounter, then reset until it sparkles.

Breeding: Hatch eggs of this line; each egg rolls at the base shiny rate (no Masuda before Gen IV).

How many you have done, or plan to do.

ChanceEncountersTime
10%lucky few864----
25%one in four2,357----
50%coin flip5,678----
90%very likely18,862----
How is this calculated?

Every encounter has the same shiny chance, the Shiny Odds Per Try shown above. Each one is a separate roll that does not care how many you have already done, so the more you hunt, the higher your overall chance of at least one shiny. The formula below turns your odds and your number of tries into that combined chance.

chance after N tries = 1 − (1 − p)^N,  where  p = 1 / odds per try

Example at 1 in 8,192 (classic full odds): about 864 encounters for a 10 percent chance, 5,678 for 50 percent, and 18,862 for 90 percent.

The table above flips that around: it shows how many encounters it takes to reach a 10, 25, 50, and 90 percent chance at your current odds. Turning on boosts like the Shiny Charm, sandwiches, or chains improves your odds, so the encounter numbers drop.

These are estimates, not promises. Most games have no pity counter, meaning no guaranteed shiny no matter how many you hunt, so even Very Likely is not guaranteed: some hunters find one early, others go well past that point.

Where these shiny odds come from: Read our full methodology

Planning a longer hunt? Set up Treecko in the Ruby & Sapphire Shiny Odds Calculator to compare every method side by side.

Treecko Weakness

Treecko is weak to Fire, Ice, Poison, Flying, and Bug. It resists 4 types, giving it decent defensive coverage. That's a lot of weak spots to cover so team support is important.

Pokedex Entry

TREECKO has small hooks on the bottom of its feet that enable it to scale vertical walls. This POKéMON attacks by slamming foes with its thick tail.

TREECKO is cool, calm, and collected - it never panics under any situation. If a bigger foe were to glare at this POKéMON, it would glare right back without conceding an inch of ground.

Treecko Ruby & Sapphire Guide

  • Sceptile gives the Treecko line the highest Speed of any Ruby and Sapphire starter, but that comes with a cost. The line is the frailest of the three and works with a thin movepool until late, so most players rate it behind Mudkip and Torchic for a first run. Choose it when speed is the priority.

Game Availability

Treecko first appeared in Ruby & Sapphire and has been available in 16 games across 7 generations. Obtainable through catching or hatching as a base form in most titles where it appears.
