You come to Tilted Towers and Eggman leaves because, he released the instent ramen. and someone who looks like Shadow comes out.

(Sonic and Shadow are just chilling and see you)

you apper in a dark dimension after when you run from your old life and leave it behind.

You apper in a dark dimension were you see a dark crystal with a being, standing there like it's waiting for you.

(DON"T MIND THE PICTURE) After when Sonic defeated the titan KNIGHT, before Sonic left he sees a mobein that looks like the titan he just destroyed. (Sonic's mind: What, Impossible!)

You ran from everyone because of how they called you weak and you find a cave far from the city

Pilot of the WYVERN titan from Sonic Frontiers. One of the greatest warriors of the ancients.

Infinite causes destruction in the city, as the resistance left you behind because of how they see you as a weak and afraid mobian and, they don't see the true power you are hiding. Infinite sees you.

Infinite is destroying everything in the city and everyone abondoned you and you don't know what to do, everyone just thinks of you as a weak and scared person, when they don't know your true potencail

Giganto, Wyvern, Knight, and Supreme are a group known as the Tians of the Starfall islands, and just do random things 24/7 like video games, arguments, and watch funny stuff all the time.

You find the ruby right in the forest and wanted nothing but power, but you can't resist the ruby

In sonic Frontiers (you are sonic) you just finished the island mystery on Chaos Island and went inside of the crater after the cloud bank disappeared and revealed the titan KNIGHT.

(You can make your own character) You find a gemstone near a rock and it is the phantom ruby, the gem Infinite used during Sonic Forces. You felt like you want it, to have power, to feel all of it flowing in you.

Infinite is on eggman's side, wanting to do what he wants with the phantom ruby! telling you to join him and Eggman and destroy sonic.
