Back Alley Mr. Mime is one of the requests you will have to complete in Pokémon Legends Arceus.
It appears fairly early in the game, but can only be done if you’ve already caught a Mr. Mime and also completed Request 14: Helpful Berry.
It will also be with Andra again, who thanks you for your Oran Berries, but has a new request regarding a Mr. Mime who is up to mischief.

How to complete Request 21 ‘Back Ally Mr. Mime’ in Pokémon Legends Arceus
To unlock Request 21, you would have needed to capture Mr Mime and complete Request 14: Helpful Berry.
Once you’ve picked up the quest from the blackboard in Professor Laventon’s office, you’ll need to go find Andra.
It’s just outside, across the small bridge and to the right. Make sure you set this mission to active as you will be running around the city a bit and that makes it a lot easier. After thanking you again for your previous helpful actions, he will get to the heart of the matter.
As far as Andra is concerned, there’s a Mr. Mime running around with bad intentions and he wants you to catch him. To start, you’ll see the creature between the houses, but you’ll actually have to go around the buildings to your right to get behind it in this part of the mission.
Once you’ve done this, you’ll have to follow Andra and the menacing mime again. Head to the new waypoint to the right of the Galaxy building and talk to Andra. Even though Mr. Mime looks closely, he has actually covered the area with invisible walls.
Then, you’ll have to go around the other side of the building and behind it to get to the Pokémon. There’s a bit of a sway to walk here, but the key is to stay close to the cliff on the left once you’re about halfway behind the building. Then you should be able to walk directly towards it.
However, this is a video game and the rule of 3 is absolute, so you must catch the monster again. Head to Andra once more and you’ll see that you’ve cornered this beastly thing. This time there is not much left to do, but a specific approach is needed.
Stand in front of Mr. Mime with the two trees to your right, walk diagonally towards the second tree past the first tree on the left and you should be able to get back to Mr. Mime easily.
Our Pokémon Legends Arceus walkthrough will help you choose a starter Pokémon and win the Kleavor boss fight. You are also tasked with filling Hisui’s Pokédex by obtaining new evolutions such as Kleavor by evolving into Scyther, Wyrdeer by evolving into Stantler, Sneasler by evolving into Hisui Sneasel, and Overquil by evolving into Hisui Qwilfish. There are a ton of new evolution methods, including some for Eevee evolutions. Take the time to complete Requests too, like The Sea’s Legend, Wurmple’s Evolved! and find Wisp locations. Don’t forget to track all Unown locations as well.
Back Ally Mr. Mime Reward
After once again capturing the threat, you will discover that Mr. Mime is actually a brother of sorts to one of the guards and regularly helps protect the village. He’s just vibrating as he creates all the invisible barriers around him, and Andra ends up feeling a little silly.
However, the good news is that this does not prevent you from getting your reward. You’ll be rewarded with two Aux Guards, which are items you can use to boost the defensive stats of one of your Pokémon during battle.
They are quite useful if you are fighting an Alpha, so there is nothing wrong with having them with you.
