That is true and I do agree that Wolf is the farthest thing from a clone. One time I was talking with a friend about Wolf possibly coming back and he said that Wolf is too much like Fox and Falco to even come back. Being a Wolf main, this got me pretty salty and I played Wolf, Fox, and Falco a lot during the Brawl days and I knew really well how each of them were different from each other (Wolf being the most unique imo) so I had no trouble explaining their differences but you have to spend some time with each of the Star Fox trio to really get to know them and how they work.
A little while ago(during the pre-Smash 4 era)I might've been slightly irritated whenever someone said anything of the sort because, you know, there was a clear difference between
and the other two(with
being quite similar to
as opposed to the relationship between
and
). Nowadays I just kinda laugh at the idea of someone thinking
is anything like them. Though I suppose he is, but not in any significant way. I didn't really use
or
, but a friend of mine would commonly fight me using
, with which I was able to make a rough estimation of the differences between the two. But really, the differences between all of them are very obvious and more so if one has at least tried them all. The similar specials and FS isn't really much to go by, ESPECIALLY for
.
