---Chat, 19, she/they. She ended up on the Surface and because of her potential (communication) she can find shortcuts in no time, she can "talk" with the environment near her to know tips and facts. She knew Demise was distracted by bug nets for example, or that Goddess walls give different items depending on what's drawn. She ended up there when Sky was still looking for Sun so she helped him during his quest, not always following him but "appearing out of nowhere" from time to time.
---Thun, 17, she/her. Thun can be found in Hyrule Town when Four is 16 to 17, some time before going into LU. She has a little tailor shop in town, and she sews clothes for both people and minish! When she arrived there, she couldn't see the minish. She was once picking mushrooms and Four stopped her right before she could destroy a minish house. That's how they met! Then Four told her everything about the minish and she offered to make them some tiny clothes. Because of this, after some time she was gifted the ability to see the little creatures and she started working with them at her shop. Her potential is "order", that stands for tidiness, but also for mental order, and this makes her sew clothes in record time
---Ami, 15, she/her. She ended in Lon Lon, but Time and Malon were already living together and they were about 30 years old! Ami's potential is "nature", she's an awesome gardener, she can heal plants, and she's a farmer too. So, she spent her time there helping Time, Malon and Talon with the ranch, doing some errands around Hyrule, and helping Time in ((an headcanon adventure I have for him))
---Piff, 13, she/her. What a cool time to end in Twi's era... Twi is in the middle of his quest, he's sleep deprived, and he has just been conditioned by the crystal ((like in the manga)) and saved by Time. Her potential is "sleep", and she can easily create potions for relaxing/sleeping, and also she creates some magic keychain and charms! She wandered a bit before going to Castle Town, where she met Twi!
---Diggi, 11, they/she. They're just a kid but already a pretty good fighter! In HW (Legends, more specifically) they use their potential "electricity" to fight, along with bombs, rods, a boomerang, and their loyal skateboard. They can't use a sword, nor crossbows, nor arrows though. They often travel with Linkle and then together with Wars and Artemis!
---Locky, 9, she/they. She's the youngest and she ended in botw! Her design is kinda similiar to the kids in the stables, but with an Hateno style tshirt! Her potential is "key": she can find lost or hidden things like a sixth sense, she can create a "magical key" from time to time, and she can create some portals to known locations! In botw the last ability is kinda useless but let's say they use that to go to high places!
