I can't sleep so have a list of Metalocalypse OCs that I haven't fleshed out but think about all the time. Lot of sibling/extended family coded. I don't have romantic OCs, so sorry.
+ Anja and Aslaug have another miracle baby in their old age and hide it from Toki (Post "Dethfam"). After a year or so, Toki finds out about the baby. He freaks out because he knows the torment that she will endure if no one intervenes, so he files for custody of the child based on past child abuse allegations. Toki ends up having to go through a very long and intimate court session that make him reveal personal and horrific details of his own abuse. He has to go through the trials gaslit by lawyer, facing conflicted fans, and the press all asking for more. The case becomes the case of the century, with every eye watching. Toki ends up winning custody after all of it and gains full custody of a little girl. He ends up raising her with the rest of Dethklok.
+ Toki was a twin. Toki and his sister were separated around 7/8ish when their parents realized they couldn't keep feeding her. She gets sent to the extended family commune to work and eventually become a wife. The parents keep Toki because he is their sole labor force for the mill. When Toki escapes, he goes the commune first to rescue his sister but only finds a grave with her name. He flees from the grave, and goes to America. His sister faked her death at the commune, and once in the grave, dug herself out and went back to her house to get Toki. She found no one and could only assume he died. They don't find each other until 2 decades later when Toki's DNA is matched accidently to a crime scene in Norway, which reveals his sister. They reunited.
+ Toki was a twin. Same as above, except Toki never went to the commune and she never faked her death. Decades go by, Toki fully believes that his sister lost to the cult and will never come back, plus he is afraid of being rejected by her after all this time. He starts getting mysterious letters one day from her, pleading to come to the commune to get her and their cousins out. The head of the family (Grandfather) has gone more insane than usual and is making threats of harming all of them, including the children. Toki, without telling anyone, disguises himself as a parishioner from another sector of the cult to enter into the commune. Charles and the band are worried when Toki disappears and tracks him down the commune. By then, Toki and his siter have executed a plan where they lead the cousins out of the commune and into the woods, where at the edge of it is a boat that they get them into Denmark. Charles and the band meet Toki at the lake, astonished, and help lead the family to Denmark. Unknowingly, the grandfather tracks them in the woods and before all of them go on the boat, he took Toki's sister and threatened to kill her if they all didn't come back. Stuck on what to do, Toki was willing to trade his life for hers, until his grandfather was struck on the back of the head. His mother, Anja, had knocked him out cold, releasing her daughter. She leaves, looking over her children and her nieces and nephews on the boat. Toki and his sister rejoice on the boat, free at least and finally together again.
+ Toki adopts his cousin, thus becoming his daughter. One day, Toki is sent to Charles office. Charles is comber and breaks the bad news to Toki that his entire family, those on the commune, had been the victims of a massacre. His whole family was gone. Obviously distraught, Toki breaks down in tears. Charles consoles him and tells him that the Norwegian police are asking him to come identify the bodies for their records. He agrees to go. He arrives in Norway the next day, and lead to the police station. There, he meticulously identifies each body of his family, including his own mother. At the end, Toki talks to the police, and shares with him details of the event. In one detail, they tell him that they checked all over the commune and show him a labeled map. Toki corrects it, saying that they missed a room. A nursery under the main hall meant to keep young children close when the women were doing their daily chores. The police freak out that they missed and place and go back to the commune, Toki rides along because he wants to see the commune. Once there, they all head into the nursery, and there, alone in a corner, is a baby. No more than a few months old, it's a little girl. She is the sole survivor of the massacre. Once identified by a birth certificate found in a bible in her mother's room, she is brough tot he hospital to be examined. Other than a little hungry, thirsty, and dirty, she was perfectly fine. Toki is then asked if he wants her, as he is the only next of kin. After much deliberation, and a conversation with Charles and the band, he agrees and takes the little girl. He adopts her shortly after and she is known as the only legitimate child of Dethklok.
+ Toki is actually the youngest sibling out of 12, not the only child. Before birth certificates, birth records were written in the family bible. When Toki's mother dies, all of the possessions in the house are inherited to him. At first, he wants to burn it all, but decides against it because he desperately wants answers to his treatment. So slowly, he goes through everything until he comes across the bible and his mother's few diaries. He also comes across a few items that he does not recognize like some old girls clothes and tools with names on them that he didn't know. Looking through the bible revealed that Toki was the last of 12 children and that his siblings before him had all died due to the abuse of his parents. The diary corresponded with the death dates along with names, their duties, and their looks. The items he didn't recognize were theirs. Toki is considered Anja's and Aslaug's miracle child at first, then described as a curse from the devil later on. Toki has the whole plot of his property in Norway searched for the missing 11 children. Once found, all in different areas of the property, Toki rests in the house to process his discoveries. He ends up falling asleep and in his sleep, he meets with his siblings, all of which are grateful for being found and hopefully properly buried soon. Toki wakes up somber but happy.
+ Murderface has a younger cousin that he absolutely adores. She's the only one in the family that he has a good connection to and genuinely gets along with. He gets an invite to her wedding, after never knowing she was seeing someone. He spends the whole day frantically trying to figure out what to wear and what to buy her. The band helps out in comedic fashion with varying results, but they are all just as excited for him. They've never met this girl but they know how much she means to Murderface. After a lot of work, Murderface pulls together a stunning outfit (I'm thinking tight jeans, low buttoned shirt, hairy chest on top, actually groomed hair, and boots. He's a southern man, this is going to be a southern wedding, god damnit.) for the wedding and a perfect gift. (This is where Knubbler and him accidently run into each other and Knubbler is hella attracted to him because holy moly.) He goes to the wedding, expecting to meet the groom and low and behold, his cousin is marrying a woman. Turns out, no one in the family knew about her and the wedding doubled as a coming out party. A majority of Murderface's family left once they realized, but Murderface did not leave. He was having an internal struggle the entire night but he could not deny his cousin his presence. He spends the rest of the night getting plastered with her and his new wife, along with the wife's family. The next morning, Murderface comes stumbling back home, looking a wreck, but ultimately very happy for his cousin. (This is also where Knubbler finds him stumbling along in the hallway and is even more attracted to him.)
+ Murderface had a older sister type neighbor that tragically died at the hands of her father. When Murderface was little, he would often sneak over to his neighbors house to spend time with the older, teenage girl that lived there. She loved Murderface very much and treated him like family. Murderface adored her to his very core. Stella and Thunderbolt considered the girl to be part of their family, as she came over frequently to help Murderface with homework and babysit. This girl has plans of leaving town after high school to become a traveling musician, specifically a bass player. One night, when Murderface is upset and won't just sleep, she ends up taking him to his first ever concert. From there, Murderface wants to play music as well and wants to learn the bass like her, so that when she leaves, she can take him with her. Problem is that the girl lives with her abusive and acholic father that doesn't want her to leave. On the night of her 18th birthday, Murderface sneaks over to deliver her a present along with his bag and bass to leave. She tells him that she can't take him, he has to stay. They get into a huge fight, with Murderface leaving. About halfway home, he feels bad and turns around to apologize. Back at the house, he climbs into her window to find her missing. From the window, he can see her father carrying something large into the fields behind the house. It's her body. He freaks, leaves, and goes home, immediately calling the police. After a lot of confrontation, the police find her and her father. Murderface has to play witness at his trail to get him convicted, which he does. After the trial, he dedicates himself to playing bass professionally, in memory of her and her dream.
