Don't feel bad if none of this convinces you or even flies over your head again. The write up took a while, but I'll just refine what I wrote down the road for future DLC character questions, so it won't end up being a waste.
I've got MvC2, but I havent really played since Dreamcast (I didnt play the rerelease on 360 much at all), and even when I did play it, I pretty much stuck to the same 3 characters
Now I just play KI casually, haha.
Squigly
*She can charge her stances and enhance her six specials in damage or function greatly
*She can create corners midstage as a point character or assist
*Her Squigly Battle Opera super has three different variations for all sorts of combo and defense purposes. Her daisy pusher super doesn't get much use, but it beats a lot of seemingly invulnerable supers/moves at times
*Not very fast, but she has large multi hitting normals and divekicks for quick mixups or direction change shenanigans. Overall she has pretty good screen carry
Kinda gimmicky, but one of my favorite characters.
Big Band
*Has three different rush punches with the heaviest having armored 75% screen coverage
*Has an air super, a cool level 3 and a juggernaut rush super. Taunting buffs damage on his rush super
*Has an unblockable ground shockwave move ala Hsien-Ko's (see avatar) Tenrai-Ha super. Other versions up close are overheads
*Has very fast horizontal grabs with one version being an AA grab on top of his regular grab
*Pretty great air superiority with a certain cymbal based air special move
*He has 3S parries
A shitton of instrument based moves makes him unlike anything in most modern or classic fighting games. His Big Body makes defense paramount.
Eliza
*Air dominance out the wazoo. She has a ton of great air normals on top her great dash and an level 1 air super
*The most damaging level 3 in the game and a great level 1 super that easily connects for new players
*Cool specials where she summons her egyptian themed bodygaurds for command grabs, projectiles or overheads
*Interesting 3 tiered dragon punch
*Projectile armored boat move that covers a ton of space and can be special canceled
*Her skeleton mode (sehkmet or segman for stream monsters) has hyper armor on everything except grabs because why not?
The most Darkstalkers character in the cast with a metric ton of BS at her disposal and an amazing array of unique Egyptian themed moves and transformations. She was probably a pain in the ass to make, but it was worthwile because she is one of the better characters for sure.
Beowulf
*Three levels of hype, each level slightly buffing his super damage
*Sasquatch (Darktalkers) based shorthop combos/resets up close and a jumping heavy punch crossup move everyone gets caught by lol
*A command grab with many professional wrestling based grapples
*Beowulf can toss his chair in different ways and use it to set up novel grab specials for slightly more damage and hype
*A level 1 with tons of invul frames, a hit based level 3, a grab based level 3 that is crazy strong if you have full hype levels and an Anti Air super
*Jon Talbain's beast cannon which lets him shoot towards his opponents in any direction he pleases. Extremely good and he can use it to position himself extremely safely even if blocked.
A heavily reset based character who can still do tons of combo damage and will easily ruin your day if you let him pressure too much.
Robo Fortune
*Beams of all flavors that range from fast and sligthly stunning to full Mahvel styled blockstun inducing beams for chip
*A beam super with three versions that does pretty good damage on each level and looks totally cool
*Not the best normals but her jumping medium punch sets up tick grabs the easiest of any normal I've ever encountered
*A magnetic level 1 that draws opponents in air hitstun back to her
*A timebomb super that lets you combo until Robo blows herself up and damages any enemies nearby
*She can create forward rushing missiles, mines or Doom's hidden missiles (overhead) by detaching her head up to three times and commanding them.
*The coolest standing heavy punch in the game that turns her into an armored buzz saw
*A very unique and possibly strong closeup game with her jumping air normals (especially air heavy punch)
She is still new, so I can't really say what her gameplan is exactly. She has certainly got a lot of tools and her beams are hell on earth as assists.
It's really not that much different from her old sprites:
And her various movements have her low to the ground in XIII, that's just the kind of movement style they went with. Even her run is low to the ground:
Think it's a great sprite personally but the haters are in luck I guess since XIV is supposedly ditching the 2D sprites.
You are seeing what you want to see in regards to her stance, but I certainly don't hate it. She and a lot of other KOF character look and animate pretty awesomely.
