## 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.
