Yo-Criminals

(also known as Wanted Yo-kai) are a group of Yo-kai which cannot be befriended, and instead must be fought and captured for a crime they committed, which mostly all revolve around vandalism. They are notable for being all color variations of normal Yo-kai.

When they spot the player, they run off, and the player has to chase them down enough to talk to them; Staminums and Bikes are perfectly acceptable to chase them down.

In the first game, once they have been talk to thrice, the Yo-Criminal will concede defeat and give up a letter/number passcode for a password, then disappears to give themselves up. Once the password is completed, the player must go to the Lambert Post Office to turn it in, which gives them get a Trophy and an additional reward.

In Yo-kai Watch 2, there are quests for capturing Yo-Criminals that become open on a set date. The player must talk with Detective Holdit on his post to acquire these quests. Once you find and catch up to a Yo-Criminal, the player will now have to fight them. Upon defeating/capturing the Yo-Criminal, the player is then awarded items as rewards.
