Anyone who thinks Lucina has a better chance than Roy is a full on fanboy. Plain and simple.
Also, Chrom and Ike won't both be playable. I keep saying they are too similar, others keep saying they are too similar. I think even Sakurai will realize that Marth, Ike, and Chrom would be too redundant.
Its either going to be Marth and Chrom or Marth, Ike, and Roy.
The argument that Chrom and Ike are too similar is biased and weak.
Ike is a heavyweight and could easily be expanded to further represent the archetype.
For Ike, give him Axes, such as the Tomohawk/Hand Axe as a 5B for some mid/long range zoning. It's a lot like Link's Boomerang but with more of a "slashy" multi-hit ability.
His 2B is now Eruption rather than Counter, it's got strong resistance to hit-stun making it a good defensive move. His 4/6B is modified, giving him less range, but more speed. It also takes much less to charge.
All of his defenses are upped so he has less hitstun, takes less damage, and less knockback from hits, thus making him more of a heavyweight, like he should. His running speed is the same, but his fall speed is faster, this is both a buff and a restriction. His jump height is reduced a bit. His attack range stays the same
His tilts and aerials are all given less delay, thus making them faster. His 4/6A is replaced to be an Anti Air attack, it is an angled hit that hits at 45 degrees above him, the range and speed on his 2A is dramatically increased to compensate for the lack of a horizontal poke. Lastly, like all characters, he's given the ability to chain and string moves together, so a standard combo for him would look like this 5A>5A>2A>8A>8Smash. All of his Smash attacks remain the same in speed, range and power, they are meant to be slow killing moves, and the best way to use them is in combos. Well, his 2Smash can be changed to be a faster move with a little less power, horizontal knockback maybe?
Overall Ike is meant to be a slow defensive character, he has deadly range and good pokes a la Sagat, his Anti Air is very fast and very lethal, his 5B Axe makes for a good defensive poke/zoning move. Due to his poor jump, his air game is terrible however, it is only good defensively, however, Aether makes up for it by giving him a good mix up move and a great recovery attack. Some of his A attacks and Aerials have replaced Ragnell with his dad's Axe, giving them different hitboxes. Likewise, his 4/6 Smash is Ragnell in one hand and his Dad's Axe in the other, thus justifying its power. Obviously he gets his FE10 getup.
Also, all of his stupid "I fight for my friends" taunts and attitude, has been changed to make him a more honorable and heroic figure. However, his personality is more Ruthless and Brutal (think Simon in Gurren Lagann), the kinda guy who get's **** done and counts on his will power to do so. Also, his ruthlessness reflect his vindictive, yet respectful demeanor from his games (he fought to avenge his father, yet still had compassion for his rival).
Chrom
4/6B is Aether, since he too has Aether, he gets it as well, but as a SideB, the only similarity with Ike's Aether here is the name. This Aether steals health from foes on impact, not much, but it still does it (a la Ragna in BB, his drive steals health), it is a Two-hit rush move, and a great combo opener.
His 2B is Holy Shield (I think it was you who suggested this), it is a temporary Ability that increases Chroms frail defenses for a while, while also increasing the power of all his SPECIAL attacks. After being used, it must be recharged before her can use it again. It recharges faster the more hits Chrom lands.
Somewhere in his tilts he has a Javelin as a weapon (Fair? or 4/6A), he throws it but it has a chain attached to it so it returns to him, it hits opponents twice. If you hit with the tip (at peak range) it hits once, but has much greater knockback, a decent killing move.
The rest of the moves will have to wait till I play FE13.
Chrom's general playstyle is a nice contrast between Marth's offence and Ike's defense. He's a very well rounded character, with a lot of diverse abilities, his specials have mediocre power, but once he powers them up with Holy Shield they become very powerful (think Tsubaki in BlazBlue with her specials and power up ability). He's got good ground and air attacks, but has less aerial range than Marth, he's also slower than Marth, his defensive game is good as far as defensive moves, unlike Marth, but like Marth, he's in trouble once takes high damage and can be knocked around easily. UNLESS, he has Holy Shield activated which lets him be more reckless (doesn't make him as tough as Ike, but still better than Marth), however, at high damages, Holy Shield lasts less time.
A far as personality, he inherits that "I fight for my friends" attitude Ike had in Brawl.
As for Marth, he's buffed to be more like in Melee, and his 4/6B is improved to be more like the Astral abillity in FE (what it's based off of), in fact I would make Marth's 4/6B like Noel's Drive in BB, where activating it changes his specials and allows combos to be stung more easlily.
With this, I no longer find them being similar at all. All 3 of them have very unique and diverse moves, playstyles and personlities.
To me, Pac-man would be a very tricky character to tame.
His movements would be very erratic from a very potent dash dance to high mobility in the air, moves having abnormally high priority and range, very potent dodges, resilience to combos and chain grabs, and a great utility move in the form of his Munch attack (can eat projectiles, good approach option, has super armor properties etc.). Pac-man as a whole would play a hit and run strategy that is designed to fake out or halt the opponents actions, but his power and weight would be below average.
He's in a sense the opposite of Mega Man. Mega Man would be more like a tank while Pac-man is more like a weasel, if that makes any sense. Mege Man would be slow, heavy, with a reliance of powerful ranged projectile, while Pac-man would be much more light on his feet with a general metagame involving suckering the opponent with varies approach options.
I'd like to see a moveset for this.
So far that Hit-and-Run approach would be ideal for Sonic, who's in dire need of a revamp.
Also, speaking about being able to eat projectiles... What if Yoshi got this?
