Super Smash Bros. Lore!

This is not official, it's some weird stuff made up by me and my friends

The Defenders

The Defenders are commanded by General Ike and fight to keep the forces of the Heavens and Hells out of the Subspace. Ike's second-in-command, Shulk, has been pushing Ike to invade the Heavens and Hells to get vengeance. However, Ike knows this would lead to the Defenders being wiped out. The Defenders possess a magical portal that goes between the world of the living and the spirit realm, allowing Defenders killed in battle to re-enter the Subspace. Ike has realized that there was no way to stop themselves from being sabotaged and simply stopped trying to set up anything, leaving both Snake and Ike with less work.
