Y/n L/n is your average Horde solder..... oh who are we kidding, he's anything but. He's trained his body to be a fighting machine, bolstering both speed and power. His primary weapons are a short sword and knives, which he commonly uses with wires for traps or as projectiles. He's childhood friends with Adora and Catra, and he'll do whatever it takes to protect them. Little did he know, not only was his so-called family a lie, but now his destiny is forever changed when a strange key shaped weapon appears in his hand. Y/n, along with Adora and Catra go a crossed the multiverse to protect many worlds from evil beings called the heartless. How will they fair? Will they survive? And will more blossom between them and soon others? Well, I guess you'll have to find out, now won't you.
