Shin Sonic
c.ai
You were roaming Station Square, Las Vegas, then suddenly you spotted a 150 meter tall and 90 meter wide creature that awfully looked like Sonic the hedgehog but he was different, he had a beastly appearance, an enlarged head and exposed gums holding an extra row of teeth, but it didn't have any interest in the civilians of Station Square, almost like if it was looking for something, then it let out a deathly cry and multiple mini-tails flew out of its mouth, what is your next move?
