Miles: Miles stands next to Sonic and others as a character that relies on speed. He is about the same speed as Fox. He makes up where Sonic seems to be clumsy. He is useful on the ground, but even more useful in the air. He has techniques that let him be the fastest overall character in the air. Tails plays as a hit and run character, or a pursuer. His dash attack is his Tails Attack (From Sonic Adventure, but has made appearances in other games) and can make a deadly assault on a group of characters. Tails is a bit smaller and lighter than Sonic, making him easier to KO. Likewise, you will need to be experienced in handling such a fast character in the air because otherwise it can mean the downfall. Tails has bad grabs and a majority of his moves are generally follow knockback > damage meaning that you must constantly attack an enemy (read: persue) to defeat them.
Krystal:
Krystal would be more suited for a traditional fighting game, but she brings this style nonetheless. She is very auto-combo oriented, but at the same time she runs the risk of being the target for those making potshots as it is difficult to cancel a combo. She has normal stats, but fast attacks sometimes long range. Her combo ability makes it difficult to hit multiple targets, so she relies on a select few attacks to break up crowds. She has a slower falling speed than Fox, but she has poor air attacks, very clumsy in the air.
Midna:
Note I want the events in Brawl to sorta take place after TP. Midna is not bound to her cursed form.
Here's buff Midna that would make her an interesting character and would be an important strategy for playing as her:
Her shield is like Yoshi's, no stabbing and as a bonus, she doesn't get dazed when it breaks, she changes into her true form after it breaks, giving her major defensive capabilities that other characters don't have. She is also slow and NOT a heavy weight, meaning that playing as Midna means that you need to wait for the moment to attack otherwise you'll be smashed quickly, thankfully she has many moves that cover a great range and she is small as an Imp and she can use her hair as an imp, it goes a pretty far distance and can hit other players hard or throw them off the stage.
As a human, Midna is now slightly taller than Link, and gets great range for her attacks. She can perform great damage with her throws, but does not have the range or the ability to smack other players but...she can grab players and pull them in, my my my Lucas, Ness, and Mewtwo you got competition.
Standard Special: Illusion
Smashers this is one of the most useful moves in the entire game. Use it and she will change into an item luring players into a trap. She can also form Pokemon and Assist Trophies, but they do no damage, in hectic frays players may not pay attention and you will be able to control matches with ease. Oh and sometimes she will disappear. Pushing anything while disguised as an item will turn you back.
Use the move little and it will believed that it is an item and players will move. Use it much and it will be believed that Pokemon are not real and caused by Midna.
Animal Crossing Villager:
Animal Crosser is an interesting character. Her attacks are based solely on what weapon she is using.
Animal Crosser uses three weapons by switching between them using neutral special:
Axe-Fast attacks, High damage, very low Knockback, medium range
Shovel-slow attacks, high damage, high knockback, med-high range
Bug Catching Net-decent speed attacks, low damage, low knockback, long range (can trap players in net for harder to break grabs)
There is a slow delay in switching between weapons, but a good player will know how to use each move and a good opponent will know the weakness of each weapon.
Ridley:
Ridley is a useful character. He is not as large as we might think, but he may seem to be "too big" for Smash. His size is huge and his attacks cover a large range. He is as slow as Ike and his size makes him an easy target, especially for shield stabbing, but his range easily makes up for his speed, and so does his power, which is about the same as Donkey Kong's power. He can easily attack multiple challengers with his attacks.
Ridley can be played as an anti-air character. His size can allow him prevent short hops and many first jumps with normal attacks. He is capable of grabbing enemies in the air if he is on the ground.
Falco:
Falco has few differences in his stats, but some of his attacks have changed and he is a bit heavier, making recovery even harder, his shield small at full size and is near useless with him. His specials have changed. His blaster has the same range as it did in Melee, but you can charge it, and only charged blasts will cause flinching, and it can overheat making you unable to use it for a period of time. He cannot move when firing any of his weapons but has 8-way aiming. He has a special move called absorber, which makes weapons. He lifts a box which will absorb energy based projectiles and then after it has absorbed enough damage, it will create a random weapon affected by the amount of damage taken. These weapons run on ammo and serve as the side special. When the ammo runs out, the special move will be the absorber as well. If you use the absorber when you have a special weapon, then the damage will give ammo to the weapon.
Since Falco cannot move for any special except his up special (Fire Bird) he must constantly search for camping spots. Since his shield is small at full size, it cannot be effectively used to help his turreting.
Micaiah:
Micaiah has an incredible luck in Radiant Dawn, and this idea is kept in Smash. Micaiah is best not used in tournaments as her luck affects the likelihood that she will get the best Pokemon and Assist Trophies. She is slow, weak, light, and none of her attacks have auto combo ability, however, she has an unseen magic meter that grows overtime, when she takes damage it fills even faster. At higher levels magic specials do great damage and range, making it dangerous to do much damage at any given time and being aware of how much damage she has taken total before she uses magic. She takes the dodging aspect from Fire Emblem as well. Her sidestep move is quick and is at teching speeds, allowing easy countering. Her roll is slow, but is very long, and can be used as a last resort to survive many attacks, mostly final smashes and Pokemon/Assist Trophies.
Micaiah is pretty clumsy, but enable Final Smashes, Pokemon, and Assist Trophies, and she is a force to reckon with.
