NOOOOOOOOOOOOOOOO-
-OOOH-kay... I don't like echo fighters very much but if they can have the properties of their normals and specials changed like the Melee clones then that's good. It's the reason why I don't hate Ken as an echo fighter. I'd give each echo fighter some different knockback angles and have their attacks deal more or less damage than their base counterparts. Too lazy to list them though so I'll just go over their specials and whatever else.
:
; Exactly the same as he was in Melee so he'd be exactly the same as... Link... He's an exception since he arrived in Smash first.
: Dry Bowser; Essentially a smaller Giga Bowser with nerfs given to stop them being boss tier attacks.
: Sceptile; Replace the water swords with it's Leaf Blades. Up Special would be Leaf Tornado which would be cloned from Hero instead, Neutral Special would be Energy Ball which is cloned from Mewtwo's Shadow Ball (Kind of silly how you cannot store Greninja's water shuriken), Side Special would be Pursuit where instead of controlling where Sceptile will go, Sceptile will automatically try to attack the opponent and deals more damage if they are facing away from it. Finally Down special would still be Substitute.
: Dr. Luigi; Ran out of characters I wanted at this point. Contrary to Dr. Mario, Dr. Luigi would be a faster but weaker version of Luigi. He would have his slippery traction and a higher jump than Luigi. His Up special is strongest at the height of the move, Down special being Dr. Cyclone with it back to being a recovery move, Side Special (Which I call the Air Ambulance) travelling faster than Green Missile and Neutral Special being Fast Capsule taken from Dr. Mario's custom special from Smash 4 (I would change Dr. Mario's neutral special to the Mega Capsule just to match it)
: Dixie Kong; Up special would be changed to the hair copter, Neutral special would be a Bubble gum pop gun, Monkey Flip grab would have Dixie jump and kick off from her opponent and Down Special would be bubble gum toss which Dixie would toss away like Diddy Kong's Banana Peel but the gum has a gooey effect instead of slip effect.
: Yooka & Laylee; Instead of a third jump, Holding jump while in the air will allow Yooka and Laylee to glide, Neutral B would be Sonar shot which has a subtle wind hit box. Holding down the button does not give them their own version of the breegull blaster, Up Special would be Lizard Leap, Side Special would be Reptile Rush. While it doesn't grant them super armour like wonder wing, Yooka and Laylee's attack is non committal allowing for follow up attacks. Finally their down special is unique being Sonars splosion. Charge up the attack to release a sonic wave that stuns nearby opponents and grants them super armour, this move can only be used 5 times per stock.
You had me with Melee Link but then you had to say modern moveset.
So it's basically a fighters pass?
