SMG4: Into the Dark Web is the twenty-first episode of Season 11 and the six hundred and twenty-seventh overall to be uploaded by SMG4.
It is also the first offically announced episode and the fourth episode of the Genesis Arc. It was aired on June 19, 2021.
Mario, SMG4 and friends go to the dark web to retrieve SMG4's USB.
SMG4 chronicled the events of his origins and his meetup with Zero, and he wanted to find SMG1 and SMG2's Guardian Pod. He recruited Mario, Bob, Axol and Melony, although Axol had to keep her company due to her being easily traumatized. They ventured to Dark Web City to find SMG4's pod, in which they stole a VPN to surf the Dark Web via the Cyber Tunnel. Along the way, onion dumps hijacked the VPN to stop them, in which the boys had to protect Melony, who were safeguarding them by hacking.
At one point, Bob was enticed by Butter Birdo, causing him to abandon ship, leaving an onion dump to scare Melony. As the rest got rid of them, Axol managed to bring back Melony, and she managed to finish the hack, arriving at a ruined bridge where the pod is. They entered with SMG4 as the passcode, and discovered a library. After some searching, an Internet Explorer slowpoke pointed the way into his origins, which was a central command. With Mario's inclever button mashing, SMG4's memories unfolded.
Young Luke downloaded something into a USB from his laptop, and inserted it into a USB port, where USBs that looked like SMG4 and SMG3's Guardian Pods are already inserted. The port lead the data, transformed into Guardian Pods, entered the SMG4 Earth, where it contained SMG4 and SMG3 in their respective pods while SMG1, SMG2 and Zero were in their black-outlined pod, fighting each other. At one point, SMG3's pod was diverted to the Internet Graveyard where it was supposed to land, but infighting within the black pod caused Zero to shoot out its orbs of energy, later arriving in the Internet Graveyard where it came into contact with SMG3's pod, teleporting him back into the overworld. SMG4 landed exactly where he was supposed to be, and the black pod crash landed in the Corcovado Mountain in Rio de Janeiro, Brazil.
Finally learning of his origins and where SMG1 and SMG2's Guardian Pod was, they celebrated, until they realized they missed someone. Bob has wandered to the cathedral, where he found what he though was SMG4's pod, when it was really SMG3's pod. As he walked away to watch Butter Birdo's stream, unaware that the antivirus subscription in the pod has expired, the eye of Zero emerged, following Bob behind.
