The title screen of "Sonic 2 and Knuckles."

When Sonic 2 was locked on to Sonic and Knuckles, Sonic was replaced in Sonic 2 by Knuckles.

This short article is in need of work. You can help Sonic Retro by adding to it.

With Knuckles's lower jump height, this makes it tough for him to defeat the boss in Metropolis Zone Act 3, as well as the final boss in Death Egg Zone.

When using a Pro Action Replay or Game Genie code to access Hidden Palace Zone, the level resets after passing the life, which in this game is ironically a Knuckles icon instead of a Tails one. Wood Zone is also much different and glitchy to go through, as parts stay stationary as the the rest of the level goes by.
