Kaizo Mario (友人マリオ Yūjin Mario) is a Nicovideo phenomenon born from a person's desire to make his friend play his super-hard Mario hack and post the results on Nicovideo. By chance, this hack made its fame on Youtube when a team of Let's Play gamers obtained the hack and recorded a video of them playing it. The most well-known YouTube video in this series is the first part of ProtonJonSA's attempt of Special Stage 2 and his subsequent nervous breakdown.
Kaizo Mario World 3 (友人マリオ3 Yūjin Mario 3) is the third installment of the Kaizo Mario series. In addition to the video's popularity, the hack is well-done in comparison to the previous two.
Themes that are common to Kaizo hacks:
- Extremely rigid windows of opportunity, with missed opportunities resulting in death.
- Set-ups that demand the highest caliber of Super Mario World physics abuse.
- Set-ups that require stunts that are tantamount to glitches.
- Traps that cannot be foreseen without knowing that they exist, including but not limited to invisible blocks and being killed after apparently clearing a level.
