Grondious | Cuphead - Wally Warbles in 47.17s - Version 1.1.5 - Charmless @Grondious | Uploaded April 2023 | Updated October 2024, 1 hour ago.
Was so happy to finally get the first ever 47 (in this patch/charmless) and while a few hours before getting this I was able to get a 47.9, I felt I could do slightly better but did not expect this low of a 47 so feeling really good about it :D

DISCLAIMER: Some of this is not new but I will detail some of the things I am going for during this fight. Also I want to say before that, that I am using a mod to see the hitboxes and bosses HP and an accurate In-game timer, this video is meant to show the strategy and what's possible as a human player (the input display does not work because for plane levels I play on keyboard and haven't set up a keyboard input display), and not meant to be a serious IL submission to speedrun.com or anything of the sort.

So right off the bat, I keep myself far away from Wally while shooting bullets to get as many bullets on screen as I can, ready to hit him as soon as the fight truly starts and he becomes vulnerable, then Wally can do several things but for this specific pattern, he goes low and does a gun which leads me to some new strategy I implemented for this RNG.

After doing a mini-bomb (and letting the mini-bomb cooldown very slightly refresh itself before switching back to bullet for some later dps optimizations which I'll explain in a second) and after the finger gun attack is done, I actually do a Luigi swapped mini-bomb EX. A Luigi swap allows you to continually shoot the equipped weapon even while in the startup animation to use an EX move and is performed by pressing weapon swap and the EX button at the exact same time.

Now while this lets you continue shooting, the EX actually coming out counts in the games code as shooting a bullet, so it sets that weapon to full cooldown, so ideally I want to have it timed so my mini-bomb cooldown is refreshed just barely enough that a mini-bomb comes out right before my EX does, so that I essentially waste as little cooldown time as possible since the EX is gonna set the cooldown (or delay until next bullet) to the max.

Doing this optimal mini-bomb Luigi Swap at this timing on this RNG actually does enough damage to progress Wally into his second sub phase where his patterns can be a little different. In this clip I get the best outcome of luck where he spits 1 more egg and then does another set of finger guns, lining up the positioning of the boss in a very advantageous way for me so I can do more Luigi Swapped mini-bomb EX's without the little birds getting in the way while still parrying birds for EX cards without losing DPS.

When reaching the main phase 2 (feather hell) I am able to damage boost and get off some more Luigi Swapped mini-bomb EX's. It is worth noting I am opting for mini-bomb EX's because Wally's hitbox is very thin and so bullet EX's do not get many ticks and thus don't do much damage. However, there is rare cases where you can get pretty good ticks in this phase 2 with Bullet EX's, but it is incredibly finnicky and so mini-bomb EX's that land in full are just way more DPS on average if you are willing to take this damage boost (don't damage boost here if you've already taken a hit).

The really good positioning I was able to set up from earlier, allows me to not have the little birds get in my way at all, fully hit the boss, and have the parry bird after phase 2 dies be in a nice spot. Then I distance myself from the boss while shooting bullets so as soon as the main phase 3 starts (baby bird) then I have a bunch of bullets already on screen ready to hit him, I also make sure to refresh my mini-bomb when going to parry the bird before the phase starts to have it ready and to have made use of the downtime while I wait for main phase 3 to start.

The baby bird phase I just get in there let out a mini-bomb and hover on it a little bit to set up for more luigi swaps and go for 2 Luigi Swap mini-bomb EX's, careful as with all of them to be close enough so that all the particles from the EX hit.

I then damage boost once the eggs get in close, stay in there shooting him with all the bullets, grabbing the parry then I finish the phase. Instantly after that I pause because pausing/unpausing here causes the last phase to spawn sooner, then when I unpause I shoot the lingering hitbox of the baby bird a tiny bit but quickly switch to mini-bombs to get a little more damage on the final phase as I get into position in the bottom left.

Here you can abuse Wally's wide hitbox by blowing him up with Luigi Swapped bullet EX's (especially with this optimal RNG that I had here), then as I unload all my EX's and he's almost dead, I let out my last mini-bomb that had been prepped from having to swap briefly to mini-bomb to set up the Luigi swap for the bullet EX's and that finished the fight off.

In theory a high 46 is barely possible which is pretty crazy to me because a 47 seemed so out of reach in the past, but I am very happy with this time for now and hope you enjoy!
