BASIC INFORMATIONSome of the following information is based off of Leafeon's "official" profile and other books from Pokemon, while the rest I have gathered from playing Pokemon. Some information may be based off of the manga version as well if stated other wise.
SP. ATK: 60
SP. DEF: 65
A Base Stat is the unofficial name for the general outline of statistics for a specific Pokemon species. Base stats usually give a general idea of the strengths and weaknesses a specific Pokemon will have. Pokemon often focus on some stats more than others. Base Stats range from 1 - 255
➾ Leafeon is one of 16 Pokemon that has a total of 525 for their base stat. This means that it averages at an 87.5 for each stat, which is decent.
TYPICAL GRASS STATSTo show a comparison on how Leafeon is to other grass type Pokemon, here is an overall average of Base Stat for Grass-Type Pokemon who are fully evolved:
SP. ATK: 89.45
SP. DEF: 83.97
Based on this, you can see that Leafeon has relatively low HP, SP. Attack, and Sp. Def, but high Attack, Defense, and Speed. Leafeon is a decent grass-type Pokemon to use based on these stats shown.
