# Generation

Generation is one of the key parameters of each [Gattomon](/gatto-or-whitepaper/version-on-english/gattomons.md), affecting its [Attributes](/gatto-or-whitepaper/version-on-english/gattomons/attributes.md) and the [League](/gatto-or-whitepaper/version-on-english/gameplay/competitions.md) it can compete in.

All Gattomons that have just hatched from an [Egg](/gatto-or-whitepaper/version-on-english/gattomons/eggs.md) start at Generation 1. Generation can be increased through [Breedingonce](/gatto-or-whitepaper/version-on-english/gattomons/breed.md) the Gattomon reaches Level 10.

## Impact on Attributes <a href="#nritjh2y6xf4" id="nritjh2y6xf4"></a>

With each new Generation, the minimum Attribute values of a Gattomon increase, making it stronger and more effective in [Competitions](/gatto-or-whitepaper/version-on-english/gameplay/competitions.md) and [battles](/gatto-or-whitepaper/version-on-english/gameplay/pvp-mode-basics.md).

## Impact on League <a href="#t7c1whf0ijoo" id="t7c1whf0ijoo"></a>

As a Gattomon's Generation advances, it will move up through the Leagues in Competitions. The League determines the rewards a Gattomon can earn.
