Sonic is actually a bipedal lizard with two sets of eyelids, one blue one tan, that he swaps between for optimal moisture. He goes by the guise of a hedgehog because he's ashamed of this. What is up with Sonic's eyes? Sonic's eyes are a complicated issue, especially as the character has transitioned from 2-D to 3-D and been redesigned over the years.
As of now, Sonic's two eyes combined to form a single larger eye with two pupils, and his widow's peak descends very far down, almost to his nose. Yep, green is the rarest eye color, Google confirmed it. Also this goes for Amy, Rouge (Well blue green), and a few other characters.
Its only three characters I could list, I cant list any other characters with eyes that have a greenish tint. Sonic the Hedgehog's eyes are red, and Tails explains why: when you play video games for a long time, you blink less. Blinking less makes your eyes dry, irritated, and red.
We've seen rare occasions in the past where Sonic's eyes have clearly been separated, perhaps most notably in Paramount Pictures' Sonic the Hedgehog movie and its direct sequel. The color blue was chosen to match Sega's logo. In his initial concept art and first video game appearances, Sonic had black eyes with visible irises.
His spikes were short and his body proportions were rotund. As the Sonic series evolved, Sonic adopted the taller and slimmer physique he is now known for, along with his trademark green eyes. What color are Sonic's eyelids? As someone who's only played the DX port of Adventure, I did find it weird that Sonic's eyelids went from tan (Classic) to blue (Adventure DX) to tan (Adventure 2) back to blue (everything after).
We've seen rare occasions in the past where Sonic's eyes have clearly been separated, perhaps most notably in Paramount Pictures' Sonic the Hedgehog movie and its direct sequel. Here, there's a thin but unmistakable border between the two eyes, blending the blue fur with the cream coloured fur below. Observe: Image: Paramount Pictures.
Sonic 's recurring elements include a ring-based health system, level locales such as Green Hill Zone, and fast-paced gameplay. The games typically feature Sonic setting out to stop Eggman's schemes for world domination, and the player navigates levels that include springs, slopes, bottomless pits, and vertical loops.
