Because they like to be seen and be diffrent from everyone else. so they do that to make them stand out.
Jules and Bernie Hedgehog are Sonic's parents.
Sonic the hedgehog
There was kinda because Amy used to have spikey hair like sonic. Yes, Sonia the Hedgehog from Sonic Underground she was sonics sister NN96
From Sonic Underground, his brother and sister are Manic and Sonia. -CNCOMICS His brother, Manic the Hedgehog, likes to steal things and although he and Sonic look alike, his hair is more wild and his fur is green. His sister, Sonia the hedgehog, is the most responsible among the three siblings. Her fur has a reddish shade and her hair has a purplish-pink color. She appears to be crushing on Knuckles the Echidna.
Sonic > Goku Super Sonic = Super Saiyan which version of sonic?
No. His hair sure does look like it though huh? When Sonic the Hedgehog collects the seven legendary jewels of HUGE power called Choas Emeralds. He uses their power to turn into Supersonic and defeat the most evil of creatures such as Perfect Chaos, Biolizard, Dark Gaia, Metal Sonic, and many more. Some say that SEGA, the makers of Sonic the Hedgehog, copied some ideas from Dragon Ball Z. I say that all of Sonic's ideas are original.
Dye your hair blue and spike it - or get a blue wig and spike that. Get a long-sleeved blue shirt and blue pants. Cut out a peach-colored circle and sew or glue it to the "belly" of the shirt. Get some red and white sneakers and some white gloves. Finally, get some blue cat-ears to wear on your head.
You could be thinking of Nazo, he was a dropped character n Sonic X
A Sonic character I made, but not on games. He's a sweet, love and caring red Hedgehog too. I make stories with him in it and also with a girlfriend name Sonia The Hedgehog (Another Sonic character I made plus she looks like Sonic, but with a flower on her hair and prom like gloves, she wears a jacket with two hearts on the front of left and right, wears jeans also with two hearts left and right. She's a beautiful Hedgehog). So that's who Sky is. There you have it;)
No the chao gets sonic hair.
Regular Form: Blue hedgehog with two spikes on each side of head (top spike pointed up w/ red streak, bottom pointed down), red eye irises, eyes pointed at top edges, has Shadow's white chest hair, base of shoes is Sonic's, bottom part of shoes has Shadow's shoe bottoms. Super Form: Golden Yellow Hedgehog, two spikes on each side of head (both pointed up but bottom spikes have red streaks), eyes still pointed at top edges w/ red eye irises, still has Shadow's white chest hair, shoes' bases still belong to Sonic's shoes, bottoms to Shadow's. Hyper Form: White Hedgehog with four spikes on each side of head pointed up (bottom 2 with red streaks), eyes still the same as mentioned, back spikes are pointed up, still has Shadow's chest hair, shoes still same w/ Sonic's bases and Shadow's bottoms
He would probably cut sonic's hair off then.
