Pokemon Go has its fair share of formidable challenges, from 5-star raids against powerful Mythical Pokemon to a Battle League filled with Trainers seeking glory in Pokemon battles. Looking in the shadows however is Team Go Rocket--the Pokemon Go version of the longtime Pokemon antagonists--and their four leaders Arlo, Cliff, Sierra, and Giovanni himself. This guide will tell you everything you need to defeat Arlo, the former Team Valor member and friend of its leader Candela.

Arlo's Pokemon

Arlo will always use Shadow Venonat in the starting position. This will not change no matter how many times you face him. Phases 2 and 3 of the battle, however, will be a different experience every time. Each phase sees Arlo choose one of three randomized Shadow Pokemon, as listed below

Best Arlo Counters

Fire Pokemon are key to victory against Arlo, as both his lead Shadow Venonat and his Phase 3 Pokemon--no matter who he chooses--can't take the heat. Your most powerful Fire Pokemon will need to be ready to bookend the battle, and we have a few suggestions:

With these you have not only plenty of fire-power, but also a few moves of other types that can help with other weaknesses. Putting Counter on Blaziken can give him an edge against Shadow Ursaring in a pinch, and Ho-oh's Brave Bird should be able to knock out Venonat after peppering it with Incinerate.

Phase 2 is going to give a lot of trainers fits, as two of the three Pokemon only have a single weakness. Manectric's Ground and Ursaring's Fighting weakness can be exploited, but it will take some Pokemon shuffling mid-match to pull off. It also doesn't help that Crobat, the third Phase 2 option, doesn't share either of these weaknesses. As such you'll need some varied movesets, so here's who we recommend:

Tyranitar is your Crobat killer, with two Rock moves that should make quick work of Arlo's flying terror. Excadrill and Machamp both have Charge Move that can deal with Crobat, but main moves that focus on one of the other two choices. No matter who comes out in Phase 2, you'll be ready.

Rewards for defeating Arlo

After Arlo is defeated, you will receive 1000 Stardust and two out of the six items listed below:
