The wolf because wolves have much more strength than otters and could probably eat the otter.
A badger would probably win. Badgers are generally larger and not as good natured as otters.
Probably the porcupine. While they are defensive creatures and their quills are not deadly, the curious otter would eventually go away.
Shadow would win in a fight, and is a better character.
Xena of course
well, if you've seen the anime movie, silver easily puts sonic to the ground using his powers, so i would think silver would win.
Sonic. He can turn invincible and fly around.
martian manhunter
Sonic, of course. Freddy only exists in your mind.....
Silver, becauseeven though he is slow,his telekinetic powers would easily keep her from attacking him. He was even able to counter Sonic the hedgehog's speed in Sonic 2006.
Otter vs Moose? Big mismatch the Moose.
giant otters eat huge animals so it is probably easy for otter to win this fight however they face few animals like this speared and speedy comet of the sea only growing to about a foot long however otters skin will protect it from a needlefish most likely its 50 50 but i think i will go with the otter for knockout win
Sonic the Hedgehog he has super speed and stuff Mario doesnt do anything except jump on turtles.
sonic
Sonic would win the fight, but sora would put in one hell of a fight.
