FAQ
What does Koffing’s number mean?
No. 0109 is this species’ stable position in the National Pokédex. It is the route key used on this site, even when a localized URL slug changes.
How are the comparisons calculated?
Height, weight and base-stat total are ranked against all 1,025 base species and again within the Pokémon’s own generation. Higher values rank first; ties are ordered by National Pokédex number.
Why can an evolution have more than one condition?
Some evolution paths have alternative known triggers, often varying by game. Each listed condition is kept separate so the page does not collapse different requirements into one inaccurate sentence.
