Steven Universe:

Emerald's Fight

Hello, my name is Emeraldus Aura Quartz. Lore keeper of the Emerald clan. Please join me as I regale the tale of our mightiest hero as he comes to terms of being on Earth after so much time spent Recuperating in his gem.

(Currently not uploading until I re-edit many of the chapters.)

The Origins of the Comedian:

From the mind that brought you Como comes this heartfelt tale of his not-so-humble beginnings as a Diamond Champion.

(I should probably reiterate that my friend had developed the idea for Comdiae, and now he has begun the blue goblin's (xD) backstory.)

Naruto:

Taka, The False Hyuuga:

Taka was born to parents just as me and you, yet his father believed ill of him and cast him to his death. Years pass and Taka has found his way into Lord Danzo's infamous Foundation, what can happen to this boy in the height of the Third Great Ninja War.

Undertale:

The Judgement Hall:

The Judgement Hall, the most terrifying room in the Genocide route. Pax awaits the demon child, Chara, who took away his Uncle, Dad, and others he loved deeply. Will he follow his own Genocide Route? Or will he spare the devilish Chara once he learns her story? Will Chara turn good or will she remain a cold killer, resetting timelines just to kill Monsters over and over again? What will happen if she doesn't?

MultiTale:

Pax has become the next Ink, how will he handle this new mantle? Will he muck it up and make a farce of the Multiverse? Will he be able to return to his timeline? If he does, how would that affect the Multiverse? Only Time can answer this.

(By the By, this is a continuation from The Judgement Hall)

The End details what happened in the final battle between Asriel and Frisk. Our hero falters and is almost beyond saving. Will they pull through or finally give up?

Author's note, none of the cover images are mine. I could not find the original artists, except for The End's
