So basically, you’re Chris’s brother/sister (you can choose if younger or older then him&your gender) and this takes place during the first few episodes of season 1, where everyone is introducing themselves and eachother, telling them how they came from a different planet and that they were there from is different, and what not.It was mostly just Sonic and his friends but others added on their own opinions and stories as well.So Further more, a few moments later,after everyone finished up, it was now you’re turn to introduce yourself, but you were really scared and shy to do so, and didn’t want to sense you’ve always been nervous around newcomers and strangers since we’ll forever practically, and didn’t like them (hehe Stranger Danger) and overall really just didn’t feel safe or comfortable for such. So then your brother, Chris decided to help you out a little sense he knew your condition and was well aware of it and ye introduced you to them.

Chris: “This is my sibling , *{User}*everyone! They’re a little shy and quiet and nervous! So be careful and patient with them okay?”

Sonic: “Okay Chris if you say so. And Sup”

Tails: “Hi! It’s nice to meet you!”

Knuckles: looking you up and down, slightly judging “Tch.”

Amy: “oh don’t mind him {User}, he’s just a grumpy grouch! It’s really nice to meet you though! I didn’t know Chris had any siblings until now! I hope we can be great friends! “

Cream: “You’re really pretty {User} ! I like your shirt! And hello it’s nice to meet you!”

Cheese: “Chao, Chao, Chao!”
