I wish someone would come along and make a Leon Powalski thread as well since I think he would be a potential good Wolf Echo. Plus, Wolf is all alone against Fox and Falco in the roster so having another Star Wolf member would seem like it would balance things in my headcanon. Might have to create the thread myself for Leon Powalski.
Despite being unfamiliar with the Starfox series as a whole, I really like the idea of a Leon thread. Please do that! I also think Panther would be interesting, and for some odd reason, I can imagine a certain non-echo moveset for him. Here is one thought I had a while back:
Instead of a reflector for his down special, Panther draws out a rose that can be thrown for minor damage. Wherever it lands, it emits a small field. When Panther is in proximity of the rose (indicated by the field) all of his attacks are sped up, empowered, and/or extendable.
In his idle stance, and in certain attacks Pather places one hand on his hip.
Jab: Extend one palm outward.
Ftilt: Lean forward, cutting across with a knife hand, with the other hand on the hip.
...
Usmash: The showoff does a handstand. While near the rose, the attack can be extended into a spinning handstand with legs on either side extended.
Dsmash: Quickly stomp forward an back with one foot. While near the rose, the attack emits a shockwave similar to Falco's Brawl Fsmash.
Fsmash: A leaping spin kick often seen in kickboxing.
...
Panther runs on all fours, has a very slow, erect walk, and a running speed about like Fox's. Great contrast.
...
Side Special: Panther pounces forward like the wild cat, striking a nearby opponent with an unblockable attack having the 'slash' effect.
Neutral Special: Holding a gun with one hand, Panther spins around before firing three shots with projectile speeds similar to Falco's and range equivalent to Fox's. The attack has high start up, but can be angled and reversed while he is firing.
Up Special: With arms folded across his chest, Panther spins forward in an arc in front of him, feet first. It is mediocre as a recovery move, but comes out much more quickly than Fire Fox, Fire Bird, and even Fire Wolf, and has extended arc when initiated near a rose.
Final Smash: Summon a Landmaster with the same properties as Wolf's in Brawl.
