I know some people were saying Medusa doesn't have a shield, which would limit her echo-ness, but Palutena only uses her shield for 2 attacks. Her dash attack, and her back air. Those could easily be replaced or slightly altered. Take Palutenia's dash attack
For medusa it would be just forming a dark energy shield or barrier at that spot. not hard to do.
Her back smash could work very similar as well, just formin g a dark energy where the shield would be during the hitbox of the attack.
As for the 2 smash attacks that involve ethereal wings, as was stated. she can use summoned ethereal snakes or her snakes in her hair instead.
I was thinking with the forward smash, Medusa could event animate the same, but the snakes come from her hair, first leaning back, then lunging forward with the same hitbox. As you can see the wings already form close to her head already, so replacing them with the snakes from her hair would be easy
Her downsmash could also work with her snake hair. Once again the wings form at her shoulder blads, and thats close to where the snakes on medusa reach., so having them grown out the strike to each side should be simple.
I did want to say something about the Up smash. while nothing needs to be changed... I kinda like the idea of changing the animation slightly. Instead of just raising her staff, I like the idea of Medusa doing that decapitating Upercut she did to Hades at the end of Upraising., as shown in ancienttobacco's post)
Keep the beam of light and the same hitbox, but also have the point of medusa's fist connecting with the beam would be the sweetspot and do massive damage. In general I see Medusa having a few"sweet spots" in her attacks to differentiate a bit from Palutena.
The up air I see can be replaced with medusa's symbol for the underworld army instead of Paluetenas light symbol.
Also, I should I said this earlier, but Palutena is right handed, and Medusa is left handed.
I don't think this would mess with the rig and attack animations too much. simply flipping the original model should work well enough. hit boxes should still have the same size and reach.
As for B moves. As everyone said Warp would stay the same. As would explosive blast. no need to edit these at all. Maybe change some of the effects a bit, like dark sparks during medusa's ward and maybe a black fire ball for explosive blast.
Autoretical I think could stay the same, just have the symbol be a dark purple, and the blast come from Medusa's snakes, as it does during her fights. she could still move her rod out but the light comes from the snake hairs, which move up a bit before shooting the attack. Could add a slow/heavy effect to the target thats hit by all 3 shots, implying a sort of petrification.
While down b could work as the counter/reflect, I think it being a modified heavenly light would be better and more fitting. make the attack dark light of course. The light is around her as she uses teleport, so we know she can summon dark light.
Final smash would have to be her Gorgon head. could work a bit like snakes final smash mixed with bowsers. The giant head flighs in the back ground, and she can pick multiple spots that fire a strong petrifying laser. anyone hit by it takes massive damage and then is turned to stone, stuck in place for 5 seconds, and then gets launched away. and other damage hit to them while they are stoned deals extra damage and adds to the launch distance.
Every other attack Medusa has can be a direct copy of Palutena's, with just added dark effects to her staff. these I feel would be the ones that would need changing. And this is not counting anything else, like frame data or speed or damage of attacks that make her an echo(like Lucina's no sweet spot or dark pits slightly slower attacks)
