YES!!!! Id ask for him to transport Shadow, Sonic and Silver to my house to hang out for a day! :D (Im not a weird fã like *COUGH*CRAZYFANGIRLS*COUGH* -3- )
If por "scientist" you mean Dr. Gerald making a dimensionla portal that wasn't necessary because Sonic aparently according to the games already lives on Earth, then yeah, it'd be pretty cool.
Nonetheless, in my real reaction to SOnic and Co., I doubt I'll be able to see them, apart from being freaked out at first. Sonic would be fairly famous, and have plenty of fangirl crowded around him in some sort of an attempt to at least get the smallest breath on their hands.
So, I'd probably just balanço by, say high, and leave, because I'd most probably still be freaked out at that point.
it would be nice, but better if WE could go in sonics world, either animal or human. anyways, teleport shadow, sonic, and silver to my house, they all don't get along well, do they?
