* ThatOneLevel: For the 8-bit version, Aqua Lake Zone Act 2 could very well contend for the title. For starters, it's completely underwater, and any Sonic fan would know what underwater means in this context: drowning. To make matters worse, it has patches of fake walls in rather nasty spots that you can accidentally fall in, and at least four big bubble dispensers you climb into to float upwards. The worst of these is near the end, which can fortunately be avoided by going through a fake wall, but if your speed is not maintained, you fall down and have to do that horrible "dodge the spikes + enemies hoping your bubble doesn't pop" section.

** Thought the infamous drowning music only plays when you're about to drown or hit the 10-minute time limit? Well, in 2-player mode, when one player finishes, the other player has 60 seconds to finish the stage or it's TIME OVER for them. So the time limit ticks down to 11 seconds and...yeah, have fun playing 2-player with someone significantly slower or faster than you now.

* DemonicSpiders: ALL the badniks in Metropolis Zone are GoddamnedBats, but the Slicer (mantis) badniks stand out the most as ''[[GoddamnedBats Motherfucking Bats]]''. Shellcrackers can be avoided by jumping over the large claw. While Asterons explode at the worst of times, they have spikes that fly out straight in a star pattern and thus can be avoided. Slicer's claws, however, are quite large, and have the annoying ability to home in on Sonic. Needless to say, they '''''WILL''''' get you at least once unless you are [[SuperMode Super Sonic]]. Small wonder why many considered it the most hated badnik in the game, if not the most hated badnik in the Genesis-era SonicTheHedgehog games, and would you like to guess who's back in the [[SonicTheHedgehog4 fourth game]]?

* ThatOneBoss: From the Genesis version: Silver Sonic and Metal Robotnik, the penultimate and final bosses respectively, which are fought aboard the Death Egg. [[OneHitPointWonder Without rings]]. Silver Sonic has a hitbox that's very small and you get no bounceback from spindashing into it, resulting in a lost life. Towards the end of the fight, it starts to shoot spikes during its spindash. Metal Robotnik protects its weak point with its spiked fists, leaving only a small opportunity to successfully hit the weak point. Touching the fists or legs results in death, and you'll have to fight Silver Sonic once again if death occurs. The latter (along with other bosses) is made even harder when playing as Knuckles (made playable with locking ''Sonic 2'' onto the ''Sonic And Knuckles'' cartridge) due to his lower jump height.
*** That is why you attack Metal Robotnik from the rear. This is done by going all the way to the right as you enter the room before the robot rises (it won't hurt you as it rises and you'll be in a safe zone once it does). You can attack the robot in its jetpack (but don't touch the flames!) His attack from this position is just by dropping mini bombs which are easily avoidable. This turned the boss from hugely frustrating to pretty easy.
** The Underground Zone boss in the Game Gear version is considered tougher due to the smaller resolution mentioned above, making it harder to avoid the bouncing balls. And that's the FIRST BOSS IN THE GAME. Every boss afterward is, comparatively, a pushover.
*** Unless you jump right on top of the boss just as the fight begins, thus leaving you bouncing in a safe zone while the robot takes damage.
