New to Skullgirls here and need some help!

Just remember I'm not a pro player & this is my opinion, although I have been playing a very long time (in relation to sg) & I've tried each character a substantial amount.

A tier Accessible Characters: characters very easy to pickup & super-straightforward. Not too many (if any) unorthodox moves

• Filia: she's the first one to pickup honestly. Very very straight forward character, has a fast air dash, dragon punch move & super...crazy mixups & incredibly easy to learn or even pickup. Assists are slightly above average.
• Fukua: filia's clone from the April fools joke that got made into an actual character. To be honest I feel Fukua is even MORE beginner-friendly, simple and just as deadly. However since filias been around longer, I include Filia first. Assist-wise...soooo many options.
• Big Band: he's actually a pretty deep character & if someone learns to parry with him well just forget about it. Taunt enables level 3 damage worthy supers with just 1 meter...assists are some of the best in-game, solid supers, solid damage...big band is an incredibly complete character & works well with any team. I just wish he wasn't so damn big lol...I hate massive characters but I'm even thinking about changing my mind.
• Cerebella: while Filia is arguably the main character of skullgirls, actually Cerebella is just as loved. With the only abstract thing being the 360 motion super, Cerebella is a strong grappler character who's actually pretty mobile & not that gigantic contrary to most grappler archetypes. Has a grab for every situation & most fearful level 3 you don't wanna get caught by lol. Super incredible assist options with her too.

B tier Accessible Characters: great overall characters, but often have little quirks to learn (usually very simple quirks)

• squigly: wow I've been seeing so much of her lately it's crazy. Squigs is unusual because she requires patience when playing. She primarily waits and reacts rather than proactively going after people. but this is good because player don't necessarily have to have a plan with her. A huge plus is that her combo structure is among the simplest in the game. However, big big damage and high level play requires mastery of a stance cancel mechanic which allows you to link chains most other characters wouldn't be able to. Actually though, this isn't the main reason she's B-tier...(in my opinion). her defence is quite horrid. If you get stuck with squigs...prepare to get stomped considerably. Despite this, she's very easy to use even ignoring cancels.
• Eliza: even more than squigs I see eliza. While I personally feel sekhmet is lacking a lot, they did the most they could with her budget-wise. Eliza is a blast to play and very satisfying. Moves are simple, but often situational. Her bnbs are pretty universal only requiring slight changes easy to remember for swaggy ones. Only real reason I feel Eliza's B tier is because she doesn't have invincible supers (but an ok DP) & this requires you to have good defence (which she has many great tools) & thus a decent grasp on elementary/intermediate skills. Despite being annoyed with this and how her taunt hardly does anything, she can be a BEAST if you use sekhmet at the perfect times. Her sekhmet mode has HYPER armour, which means it can go through any move. Only thing you gotta watch out for are throws & hit-grab attacks along with snapbacks. But again, if used pre-emotively, you'll make a lot of people paranoid. Oh & her tag-in is GODLIKE. You can even get full damage combos off it :) Or even combo INTO her tag-in with all characters. So yeah. Also has a healthy assist-game.
• Parasol: I don't know incredibly much about parasol but from playing her, she seems super transparent in regards to moves. What you see is what you get. She IS a charge character meaning you'll have to get in the habit of learning to hold back a lot, but aside from that, she is a well-balanced character with a plethora of tools. One of the most annoying dp's in the game aside from big band & lots of command normals for beginners to randomly play with and confuse opponents.
• Peacock: while easy to spam projectiles with peacock, you actually have to know what you're doing as a solo one. With an assist, the difficulty level goes down dramatically, but as a solo, she has limited tools to get in besides trying to use falling items to keep opponents locked in block animation so you can decide to go low or throw right as they try to do something. Many like peacock & she's actually pretty simple and might actually be argued an A-tier, but in terms of accessibility many of her moves require you to get used to unique spacing, mindgames, and timing.
• Valentine: an incredibly solid character & famous for being point & building meter quickly, Valentine is the fast rush down character. He reason she's B-tier is because she actually doesn't have a normal air dash. It's at an angle. Also many of her combos require specific timing and often needs to adjust combos specifically from character to character. Most normals aside from her lights aren't to be used outside of combos & can make getting in with her hard for new players. Her grab is pretty infamous, but it scales damage and makes you do more work in the end having to reset or settle for half damage. Assists are TERRIBLE though...tag-in however, not too bad.

C Tier Accessible Characters: usually have uncanny ways of moving or 2 quite different forms or modes of fighting. If not that, they might have very limited tools for getting in.

• Fortune: Fortune is a character that's kinda weird. You can play with her in 2 modes: head on or head off. Head on is more powerful, but neutral is much harder. Head off is easier to get in, but weaker and often needs meter. Learning to switch gracefully between the 2 &/or use both masterfully is key. You COULD just learn to use one mode...then work on the other & in that capacity I suppose she'd be A or B tier, but assuming you wanna have her as one of your mains, it wouldn't be good to limit yourself like that. Great character, but much to learn.
• Beowulf: I LOVE Beowulf and he's probably the most fun character in the game to be honest, buttttt the way he moves around requires a bit of forethought. He has a tiny little hop which opens up many options to confuse foes on their wake up. But when trying to get through zoning...if you don't have a handle on him, it won't work. Also, he, like fortune has 2 modes: chair & no chair. Combos starting with the chair will do the most damage, but you often need to throw it as a projectile to get in. This COMPLETELY changes most of his fierce strength moves, thus changing his combos drastically. Beowulfs damage is AMAZING & honestly doesn't really need meter to do damage as his bnbs are often comfortably above 7k -- what some characters struggle to reach even with meter. Has a very cool taunt mechanic and increases damage to some supers with it. Assists are meh...but his wake up options are pretty good with & w/out chair. If mastered, this character will RUIN anyone he gets his hands on (literally). One of the most complete characters but quite a learning curve needed.
• Double: double is weird in that she borrows moves or forgotten moves from the rest of the cast and makes combos putting them together. She's incredibly damaging, but if an opponents defence is good, it could be hard to get in with her. She has one of the best j.hps in the game & is one of the best anchors...but you really need to be solid with her & have a bit of an idea of how the cast works before getting to her. Also a very annoying DP assist.
• Robo-Fortune: the newest DLC character & in my opinion one of the most creative & flavourful characters in the game if not the most. Unfortunately though it doesn't negate the fact she has a bit of an abstract move set....so Fukua & peacock are zoners through & through with at least 6 types of long distances moves each. But robo-fortune...yeah, she has 3 strengths of lasers which are very effective & REALLY REALLY annoying if done right. They reach the fastest of any zoning move too, but her remaining moves are HIGHLY situational. In fact 3 require her to create floating head drones (c.hk). Unless in the corner, they're not comboable either. And her wake up is simply atrocious. Probably the worst in the game. No invincible supers & her tag-in is one level above atrocious. Combos require precise timing & her assists are meh...try her out by all means but in my opinion I feel she's not a great character. Don't get me wrong, all characters can kick ass at this game but her tools are limited to this half-zoning thing & half..idk. Anyways, I'd rate her at tier D if I could.
• Painwheel: actually not really a hard character per se...but you need to master flight cancelling & as a squigly player I NEVER was able to get it despite only being the opposite motion. Just need more time with her I suppose. Know this: if you see a Painwheel player, WATCH OUT. This character strikes fear into the hearts of many including myself. Painwheel can fly around the screen & knowing when to hover is something you gotta learn. Also half of her normals can be held down to give her armour. Whatever attacks she absorbs is inflicted back on the enemy from these attacks to my knowledge. Not sure if it's 100% retribution but it's enough. She's a very deep character & a pain (haha) to fight against but satisfying to use. If you want a challenge & a good character I'd pick her. Assists are good enough and wake up game is alright I suppose. Been thinking about potentially picking her up myself.

Remember this is just an accessibility tier list. I tried to figure in actual tier a little too, but I think it's pretty accurate. In short, my recommendation...: Filia is a great character to learn basic mechanics of the game. Parasol or Eliza if you think you want a medium challenge from the jump & Double if you wanna sizeable challenge.
