10 Video Game Bosses You Had ONE CHANCE To Fight

10. Jade - Mortal Kombat II

Jade first served as a playable kombatant in Ultimate Mortal Kombat 3. However, the Edenian warrior debuted as a secret opponent in Mortal Kombat II.

While playing the main campaign, the player must defeat the fighter before Shang Tsung with Low Kicks to encounter Jade. If the player presses any other button during the bout (including block,) they lost their chance to fight the emerald-robed assassin.

Despite the fact the player only needs to beat Jade in one round, winning is no easy task, since she moves at double-speed. On top of that, Jade performs input reading, meaning she reads her rival's attacks while they're executed, allowing her to counter any move with ease. Spamming projectiles and sweeping are effective against other enemies, but using tactics like these against this masked minx is a guaranteed death sentence.

If the player loses (which is extremely likely,) fighting Jade will no longer be an option, since they move onto the next challenger, without being offered a rematch. Defeating Jade bares no reward, but it's still a highly coveted title, since she's provides such a merciless challenge.
