I'm having the same problem. Us Wolf mains really got shafted, huh?
Like I'm not seeing any characters that have quite the same kit. Significantly better air mobility than ground mobility, a good juggling up aerial, a powerful down smash, an interruption projectile, a get-off-me special (reflector), one throw (down throw) that is bizarrely much better than the other three, amazing poking aerial, fast normals in general, etc.
Robin and Jigglypuff possess some of these qualities, but not enough for it to feel the same to me. Robin has no air mobility and laggy attacks and Jigglypuff's lacking in the specials department. It might be a bit of a stretch to say it, but I think Palutena has some similarities to Wolf as well; Auto-Reticule halts foes at mid-range, Reflect can push away foes right in front of you, her forward aerial is as far as I can tell a great poke, her down throw is hella good and combos into forward aerial for free, up aerial is a good juggler, etc. She has one of the fastest running speeds however, which contrasts Wolf immensely and (most of?) her KO moves don't have fast startups. So again, I can't see a perfect match to Wolf.
