Stats & Training
Speed and Attack carry most of Rattata's stat budget. Sp. Atk's the obvious dump stat. Easy to catch and yields 1 Speed EV. Follows a medium-fast 1M XP curve.
A RATTATA is cautious in the extreme. Even while it is asleep, it constantly moves its ears and listens for danger. It will make its nest anywhere.
Rattata Weakness
Rattata's Normal typing leaves it vulnerable to Fighting. It shrugs off Ghost-type attacks completely. Just 1 weak spot to worry about, which keeps teambuilding straightforward.
| Damage | Types |
