June 23, 1991, which is when the first Sonic the Hedgehog game was released.
Tails wasn't introduced until the second (or arguably third) sonic the hedgehog game. Fans responded generally positively to him particularly in Sonic 3 where he introduced an alternate gameplay style to Sonic.
No, the First Doctor did not have a sonic screwdriver. The sonic screwdriver was first introduced as a tool for the Second Doctor in the classic series before becoming a staple for all subsequent Doctors.
First game was made in 1991
The US and EU birthday of Sonic is June 23, 1991. (the year he was introduced) However, his age is fixed at 15.
Unfortunately, Super Sonic was not introduced into Sonic the Hegehog 1 (Genisis and GameGear) until Sonic & Tails (Sonic the Hegehog 2). So, no, there is not. Unless, of course, that you hack it. I do not recommend hacking Genisis games. It can damage your system.
You don't, Tails isn't playable in Sonic 1 because he wasn't introduced until Sonic 2. I'm sure you can find hacks of Sonic 1 that let you play as Tails though.
Silver the Hedgehog is a fictional computer character first introduced in the Sonic the Hedgehog series. Games that Silver the Hedgehog has appeared in include: Sonic the Hedgehog, Sonic Rivals, Sonic Rivals 2, Sonic and the Secret Rings, Sonic and the Black Knight, Sonic Riders: Zero Gravity, Sonic Free Riders, Mario and Sonic at the Olympic Games and Sonic Generations.
In the real game no, because Tails wasn't introduced until Sonic 2. You can however use hacks people have created to play as Tails in Sonic 1. Try out this one on Sonic Retro, that allows you to do just that
The only Sonic anime that has run regularly since Silver or Blaze were introduced, and neither character was in the show.
This is not possible. Sonic collects the Time Stones, not the Chaos Emeralds. Besides, the concepts of Sonic CD were being drawn up before Sonic 2, the game which introduced the super form. So, like Sonic 1, the concept of Super Sonic hadn't even been invented when the game was being created.
Scourge he was known as evil sonic before he named himself scourge but all in all he was first Technically, Manic was introduced first if you are talking about Sonic's brother from Sonic Underground.
Sonic doesn't have a girlfriend however back in the 90s, the Sonic the Hedgehog manga(1992) introduced Amy Rose as Sonic's girlfriend. Amy was later introduced in Sonic CD, and Sonic Team changed her role from Sonic's girlfriend to Sonic's admirer. Sonic has been running away from her for 4 years until he stopped after the events of Sonic World Adventure(aka Sonic Unleashed) and has fealt comfortable with her ever since but not enough for him to accept her as his girlfriend. Note: Since some fans get the Archie canon confused for the main canon, they mistaken Sally Acorn as Sonic's girlfriend even though she doesn't exist in the games.
