Super Smash Bros. Lore!
This is not official, it's some weird stuff made up by me and my friends
Ryu
Ryu was created by Jigglypuff using dark magic in an attempt to create the ultimate warrior and turn the tide of the war. After realizing he failed miserably, he cast Ryu out of the Nine Hells (into the Outer Wilds) and created Terry instead. Ryu was pretty mad about being rejected and abandoned by Jigglypuff, who he thought of as his father, so he decided to go on a training journey. His goal was to become strong enough to fight his way through the Nine Hells and prove himself to Jigglypuff. Sadly, Little Mac didn't respond to his e-mail, so his only opponent was Ken (who always loses). Ryu eventually realized his training journey wasn't going anywhere, so he decided it was time to return to his father's domain and prove himself worthy. Ryu had heard rumors of a powerful magic hermit that could help him get to the Nine Hells. He journeyed across the Outer Wilds and eventually found him. Ryu was very surprised when he found out that the powerful hermit was a 7-year-old named Ness, so he bullied him a little but then asked for help getting to the Nine Hells. Ness refused, because he was mad at this rando who had just broken into his house and bullied him. Ryu threatened him because Ness was just a 7-year-old, but Ness had strong magical powers. Ness said, 'Ok, fine. You want to go to hell? Then GO TO HELL!' and psychically threw Ryu to hell. Ryu lost consciousness from the G-force of being thrown to hell at over 8.5 million Sephiroths per hour, and when he woke up, he didn't know where he was. He saw bright pink girders, and heard retro music playing. Then, a springlike object fell towards him. He tried to dodge it, but he was trapped in 2 dimensions so it didn't work. As the spring hit him, so did the realization: He was in the 7.5th layer of Hell, also known as 75m.
