The Protector from Etrian Odyssey aka Shisho
Overview: If any character from EO would be choosen, it'd have to be her, being the mascot of the series and all.
There have been others(Gunner, Sovereign, Fortress and Fencer, all white blue-eyed blonde girls. I think I'm seeing a pattern here) and even Medic(or Medi-Ko as she's known in the Explorer's Log) but Shisho was the cover girl for the first two games, is constantly chosen for merch and even has a DLC portrait in EOV.
The Protectors play the role of tanks in the games they appear, so naturally, she'd have a more defensive based moveset.
Costumes:
Shisho might be the main one but there are other Protectors so they deserve some recognition
For the other four, there are many choices, they could either be based on the Etrian Mystery Dungeon skins for the first two
(Unfortunately, the other two don't show up in EMD)
Or be skins based off the other tank classes:
Hoplite
Fortress
Dragoon
(For the sake of consistency, the shield would always be the same format as Shisho's)
Stats:
Speed: Slow(slower than Robin)
Weight: Heavyweight
Fall speed: Fast(about the same as Ganondorf)
Jump: Low(a little more than Little Mac's)
Passive traits: much like Link's Shield, the Protector's will block projectiles if they're standing still. Also, their shield will receive less damage if they're attacked from the front.
All attacks that use the shield will act like Palutena's and will block any ajd all hitboxes
Moveset:
Normals
Jab: two horizontal slashes followed by a vertical one
S-Tilt: a sword stab
D-Tilt: stabs the tip of the shield downwards
U-Tilt: bashes the shield upwards
Dash Attack: Shield Rush-using the tip of the shield, she does a punching motion with it while sliding forward a bit
Aerials
NAir: puts the shield in front of her creating a sex kick hitbox
FAir: slashes in a vertical arch forward
BAir: bashes the shield backwards
DAir: performs an overhead slash while entering a stall-then-fall state
UAir: performs a slow circular half-moon slash over her
Smash Attacks
Side Smash: Shield Smite-Tackles while bashing her shield in front of her.
Down Smash: smashes the shield downwards in front of her using both hands
Up Smash: stabs upwards with her sword
Grab: grabs using her right hand
Pummel: knees with her right leg
FThrow: kicks the opponent with her right leg
BThrow: holds them with both hands before turning back and throwing them away
DThrow: falls with her shield over the opponent
UThrow: stabs them before throwing them upwards
Specials
Neutral Special: Fire/Ice/Volt Jar-Releases one of the items in front of her, always following that order. Once released, they'll go diagonally down like Robin's Arcfire.
Fire Jar will launch a fireball and explode once touching the ground or an opponent, releasing smaller fire balls around randomly. Ice Jar will release an icicle spear that'll freeze at higher percentages and keep going even after connecting. Volt Jar will release a thunderbolt that stays for a split second, stunning anyone hit by it.
Side Special: Elemental Wall-The Protector will put her shield forward and reflect or block any projectile that has Fire, Ice or Electric properties. Projectiles like Lucas's PK Freeze will simply be blocked while ones Mario'a Fireballs will be reflected.
Down Special: Parry-It's a counter, do I have to explain it in detail?
Up Special: Ariadne Thread-While grounded, marks a spot in the ground. In the air, warps her back to the spot marked. The mark will disappear after the move is used again.
Final Smash: F.O.E.!
A giant "!" appears in the middle of the stage and a fomidable orange enemy...
...which will move around the stage and pursue the closest enemy, trapping them and anyone near them inside it before damaging and launching them away
