It is highly implied that Elise did indeed love Sonic throughout the storyline of Sonic the Hedgehog. Shown through Sonic's Trial of Love, a cutscene where Amy confronts Elise about her liking someone, and most controversially, a scene which Elise revives Sonic through the use of a kiss, telling Sonic to come back to "us".
Sonic is not currently in love with anyone, at least in the official canon. Amy Rose has had a major crush on Sonic since Sonic CD, but Sonic does not return the favour at all. In the Archie comics and 90's cartoons, Sonic was in love with an original character called Sally Acorn. In Sonic 2006, there is an implied relationship with Princess Elise.
I think Sonic remembers Elise, because at the end of the game he arrives at the festival and tries to see her
Yes.
In the Xbox game... Sonic dies and Elise kisses him to bring him back What happened was that a mysterious hedgehog, Mephiles, was trying to get the new characer, Silver, to destroy Sonic. With the help of Shadow, Silver discovers the truth and spares Sonic to help him out. Then, Mephiles impaled Sonic with a laser to destroy him. That made Elise cry, which was to realease the Flames of Disaster, which was Mephiles's whole objective and interest. Elise then gathers with the others to revive Sonic with help of the Chaos Emeralds. Elise then kisses him, making Sonic turn into Super Sonic. Then, Sonic shared his Form with Silver and Shadow to destroy Solaris. Once destroyed, Solaris's true flame appears. Elise blows out the flame, setting back time as if Solaris never existed. At the celebration remade, Sonic rushes through the crowd, and Elise rememebered who Sonic was. Then, it was all a happy ending! Dude! Sonic Didnt Kiss Elise! Elsie Just had to do it. But its not true they love each other.SONIC WAS NOT DEAD! The Blow pushed sonics soul out but his soul was still in the air trying to go back. HEAR CAREFULLY! Elise said " I Can feel his soul."
Mephiles "killed" Sonic, so he could release the Flames of Disaster which were sealed inside Elise. The Flames were unleashed due to Elise crying.
yes
you dont see her but elise does say that she died when she was a child
(Event) Elise's Tears
Tha depends on your opinion.
Sonic died in Sonic the Hedgehog 2006 when Mephiles impaled him with an attack from behind. But Sonic was brought back to life by Princess Elise and her wish on the Chaos Emeralds.
Elise and Maria are humans.
