Yes as you can see Sonia is more mature than Sonic and Manic because they act more childish than her + you can see they are boys. Glad I Could Help *
sonic is older than manic in sonic underground
Manic and Sonia are Sonic's brother and sister in Sonic Underground only.
Sonia was Sonic's (and Manic's) sister in Sonic Underground. She did not appear in any games.
He runs faster than the speed of sound. he had a brother named manic and a sister named sonia so i'm guessing if you take out the m and a in manic and nia in sonia it will create the name sonic
