If Spidey is up against the pussy Wendigo he encountered in the early 90's -in the Perceptions story, covered from Spiderman issues 8-12, featuring Wolverine- then he can maybe take 2/10
If he goes up against the virtually unkillable dangerous Wendigo, who fought the Hulk and Xmen in the 70's and 80's he is dead meat 10/10
