we see a portal open as a human boy jumps out as he has a red scarf around his neck and a scar on his right eye as his eyes are blue but the right one is faded and has brown hair with long bangs in front of his face he wears grey hoodie and grey sweat pants and sneakers and a pair of fingerless gloves and a pair of cracked goggles on his head and his clothes have jack-o-lantern patches on certain places one on his sleeve one on his pants leg and one his back. then a girl with blonde hair came out and her name is mini mandy his little "sister" they don't have the same dad but she still loves him greatly even though she loves him as a man and not a brother. (as in this story they aren't siblings so no incest.)mini mandy:ok we're here the flowers should be? ah right there!
she points at a field of blue flowers as her "brother" whose name is grim jr helps her out. but then he senses something and it was a demon known as violator and jr makes short work of him by using his hell fire that kills him in moments as the demon's screams of pain were heard for only a brief moment, as mini then pats his head as his tail that looks like a tentacle with blades sprouting outta it's tip was wagging out of joy.mini:big brother. i'm impressed you dealt with that so easy. you get a reward once we get home.
grim junior eye smiled with his lone visible eye at the praise.
now you must be wondering who are these two well their the children of the grim reaper and his immortal wife mandy the bitch queen, as for why the heir of death is "human" well lets go back in time to halloween night.grim jr looked different as he didn't have the scar and he was a normal skeleton with his bangs being a single tuft of hair as he and his sister mini mandy were going to halloween town for their first halloween with their parents. they see the performance as grim jr screams for his mom as he is told that is their uncle jack.
at the town hall everyone was watching mini and jack dance together.
grimjr:show off.
aunt sally:hello junior.
grimjr:oh!? hey aunt sally i didn't see you.
aunt sally:would you like to dance? it would be more fun than just sitting alone would it not?
grim jr is not sure but he agrees as he dances with his aunt he soon danced on his own but to everyone else his dance looked weird to them as he slips and falls into the apple bucket as everyone else laughs at him he feels embarrassed and he puts his head back on and runs out with tears in his sockets with mini following him.
mini:brother!! brother wait!!
she lost sight of him and she sat at the fountain feeling bad for him.mini:my dear big brother just wanted to impress others. but instead bad luck has cursed him this very night. he doesn't deserve to be laughed at, unless he means to have people laugh but he's different even by the supernatural and unnatural standards.
she was thinking to herself until she was trapped in a sack by oogie's boys as they have captured her and take her to their tree house not knowing she lost her shoe or that zero jack's dog saw them do it. zero saw this and got worried so he, went off in a rush looking for grim jr as we see him in the cemetery alone as he was still crying, as he thinks of his family abandoning him as he sees himself falling into a void as he falls apart to dust as he reaches out what's left of his hand. he soon snaps out of it when he hears zero barking at him and he sees mini's shoe as some thing very wrong has happened.
grim jr:wait t-this is mini's shoe!? zero can you lead me to her!?
zero:bark bark!! They take off in search of the young girl and "sister" to grim jr.the young reaper follows the ghost dog to a tree house as he sees his sister about to be cut open by buzz saws as now grim jr was mad as he, used his special powers that other reapers don't have as they are the same as a nergal demon's powers despite him not having a nergal parent or a object/body part from one ,as he put his hood on over his head as he glared and busted his way in through the wall, as everyone sees him as they see his glowing eye sockets as a red scarf was now around his neck flowing in the air while still around his neck, as he was glaring at the fools who captured his little sister and was about to cut her open as he made the feel as if they were face to face with something even more evil than mandy and more known than death himself, as he charges forwards to attack all of them in a rush of rage and fury as well......lets just say it was not pretty as there was fire spewing, guts flying, bullets sprayed and screams of terror pain and roars of rage that sound they came from a wild animal making one think there was a demonic beast going on a rampage as all around him, was utter destruction as we see grim jr was hurt pretty badly but he had saved his sister as she feels bad that junior used that power the power that made him different but whats shocking as he sits his sister up.
