BEST BOLD NATURE POKEMON
Walls that use status or special moves love Bold. 10% more Defense and Attack goes down, which doesn't matter if you're not clicking physical attacks. Over in Ruby & Sapphire, Lugia is one of the most popular Bold users, alongside Clefable and Zapdos. Synchronize is your best bet for Bold in Ruby & Sapphire. Lead with a Synchronize Pokemon that already has it.
