After defeating the Elite Four and finishing the main storyline, you will be able to start battling and catching the Ultra Beasts through the Looker Storyline. The second Ultra Beast you are set to capture is Buzzwole. Like all Ultra Beasts, Buzzwole has some pretty incredible Stats. It's more of a Physical Pokemon, with high stats in both Attack and Defense, but it's also bulky with nice HP. Luckily it's a Bug/Fighting Type, which means a player can disable it with paralysis.
Here Are Some Tips For Catching Buzzwole:
Like many of the other Ultra Beasts, you are set to catch more than one Buzzwole, two to be exact. It can be found randomly in the Wild Grasses of Melemele Meadow. Since it is at Level 65, a player can easily put a Level 60 Pokemon at the lead of their party and use a Repel to quickly find Buzzwole in this area. A player will know they are near this Ultra Beast by a change in the music and a not-so-far off cry from it.
Like most Legendary Pokemon, it's best to try to Paralyze Buzzwole first thing so you can always go first. Right as the Battle begins, Buzzwole's Defense will increase by two stages, so make sure to go after its weaker Special Defense with Special Attacks. From there, try to lower Buzzwole's HP as low as you possibly can. Moves like False Swipe and Hold Back work great when it has low HP, ensuring to leave at least one HP.
But keep track the more Pokemon Buzzwole knocks out on your team, as its Highest Stat will increase every Time it does so because of its Beast Boost Ability. Because of this, like all the other Ultra Beasts, it's best to try to capture it as quickly as possible with the Beast Ball, since it has a x5 Catch Rate with Ultra Beasts. But don't be afraid to use Ultra Balls or either Nest Balls on Buzzwole, as they both work well on it.
And don't forget to ALWAYS save before trying to find Buzzwole. It's a safety precaution, one that has worked since the first generation of Pokemon.
