Cyborg Justice was great. I only learned recently that no, pits were not just a death sentence if you didn’t have the pneumatic legs, you can transition out of a jump into a forward lunge to get the distance you need.
Pulling robot pieces off and attaching them to yourself was an amazing mechanic. Same as kicking legs back upright and slamming torsos on to resurrect enemies (and possibly allies?)
And the music is peak Genesis music.
Confirmation from the Sega Genesis Sonic 2 manual:

Two images, one of the front cover of the instruction manual for Sonic the Hedgehog 2 (giant shadowed Doctor Robotnik head and arm in the background, reaching for and clutching a giant checkered numeral 2 in the middle ground, with Sonic and Tails in the foreground, with game title and the text INSTRUCTION MANUAL below them, with the console logo at the top with stylized text reading SEGA GENESIS / 16 BIT CARTRIDGE.
Second photo: the manual opened to page 10 (greyscale), title text Super Items, description text: Spin, bash or bounce to break open monitors any way you can – to get the Super Items inside.
Five square pixelated images are arrayed in a row beneath the text: a shoe, a ring, Sonic’s face, three four-pointed stars, and a circle with a horizontal gradient.
Beneath these is a bulleted list of names and descriptions:
Under this list is a cropped screenshot of Sonic in a shield sphere, with Tails behind him and a mechanical preying mantis in front, the latter of which has launched small curved blades at Sonic’s shield.
The following page is visible in the photo but is outside of the scope of this post. It’s about Star Posts.
