Hello. My name is John, I'm Greek and I am a huge Sonic fan! I've been making content related to Sonic since 2017. I admire Sonic from a very young age and that's what made me start this youtube channel. Here's the content that you'll find on my channel: Sonic Content (Fangames, mods, etc) Sprite Animations (I have been animating since 2021 and I enjoy the process of it. I'm trying to get better by the time to offer you the best sprite animations!) Sonic.exe Content (Not as often as I used to) Off-topic videos (On streams only) If you enjoy my content, consider subscribing and turning on the notifications bell! Profile picture by: Ri_red03
