the s in super to me looks wrong

@HyphenK: Just now seeing this reply, and you were right, Knuckles does not have jump off screen like Sonic does in his endings.

@MilesPrower88: The ending sprites shown at the bottom are the only ones that Knuckles has and are only seen when you get all the Chaos/Super Emeralds.

The giant sprite when you get the good ending as sonic. It doesn't show up as knuckles because knuckles doesn't jump off screen.
Or maybe he does idk

@MilesPrower88: Can you be a little more specific, please?

where's the sprite that shows up when beating the game as super/hyper knuckles

I'll see if I've got some spare time to put them in tomorrow. It's already late where I am to get started with a revision today.

where are knuckles' chilling sprite, from the mushroom hill intro ?

Where are the blue sphere knuckles sprites?

Palette limitations. Basically, the palette works like this:

Line 1 - Sonic/Tails (or Knuckles if playing as him), Robotnik, most General Objects and Monitor Screens
Line 2 - Rings & Ring Screens, Badniks, Knuckles, Boss Units
Line 3 - Foreground
Line 4 - Background

Each line has 16 colors, with one of those being the transparency. As Sonic's blue shades occupied a key part of the line, and the rest of it taken up with objects or the other colors on Sonic, there was no room for Knuckles' palette on the same line. So it went to the second line, where the green was affected by the gold color of the ring. This is much more pronounced when fighting him in Hidden Palace Zone.

Why was Knuckles the wrong colour in S3 alone?

Spoiler:I'M HARD AS NAILS, IT AIN'T HARD TO TELL, I BREAK EM' DOWN WHETHER THEY SOLID, OR FRAIL

This sheet lacks raw colors, and on top of that doesn't use consistent RGB values, I'm sending in a fix.

EDIT: I just sent a revision that's color corrected

& Knuckles

@NARbluebird_YT Mister Man ripped everything and edward2005new ripped the horizontal pole spin sprites because they were missing. (It also has a startup sprite)

"ripped by Mister Man"
"Ripped by edward2005new"
Well, which is it?

@Dolphman horizontal poll where visited ripped by edward2005new.

Missing horizontal poll sprites were added, which have a unique starting frame.

So... what's new on this sheet ?

unlike sonk he no chukl

It's BLOW thrower, not "bloat" thrower. "Bloat" thrower doesn't even mean anything.
