Ok so I vaguely had this idea that was really stupid for an Undertale thing with my friends but long story short part of it was that Chara was brought back to life because of weird timeline stuff and was sort of given a second chance at life. 

My idea here I guess would sort of be to go deeper into the relationship of Chara and Frisk? As like, fellow determination humans. Not like Charisk. ...ok MAAAAAYBE but even if its a little weird I ship Frans but you never know.

I mean this would be after several RESETs and timelines, both pascifist and genocide, just barely falling short of the true happy ending and having to start over.

Also, I think this would probably be based somewhat off of that song above, because from this that is kind of how I think of their relationship. Maybe not the pictures, but the lyrics I really think fit my thoughts on the relationship between Frisk and Chara well.

Frisk blearily looked up. An almagamate he was unfamiliar with had knocked him out and he was trying to get a grip on his surroundings. He had been to the True Lab plenty of times before, but had not seen this scene before...? "Stay alert Frisk." That feminine voice echoed in his mind. Hpmh. This is another one of your stupid tricks, isn't it? "No. I don't know what's going on. This isn't supposed to happen, why are you strapped into that DT machine? It's broke and this is unnerving me." Frisk's mind snapped to attention when Chara said that. He looked up and his arms, which were eagle spread above him in a small space that looked to be behind what Frisk had always thought were the strange pincers of the DT machine. Before he could figure out what was going on, the hum of machinery starting up echoed throughout the room, and there was a glimpse of the foreign amalgamate between the pincers. "Hey! Let me out!" Frisk yelled to it and pulled against the cuffs that were holding him in place. "Frisk!" Chara yell was drowned out as a dull red started to glow from the cave Frisk was in. "DT  extraction machine status: active." an auto toned voice reported. It's never been active before! Frisk panicked in his mind. The red glow grew brighter, and a searing pain grew in the boy's chest where he knew his soul was. He heard someone screaming, and vaguely had the thought that it was him and Chara yelling his name before he passed out.

She slowly lifted her head, blinking weakly as she took in her surroundings. She was on the ground of the True Lab, and she wondered idly how she was able to get so close to the actual ground without ghost physics coming into play. Guess I DO know when Frisk gets out cold I do as well...  her eyes drifted over to a small limp shape in front of the threatening Omega Flowey-like machine. "Frisk!"  she cried and scrambled over to the one they had watched over for so long. Her legs felt weak, as if they had not been used in years. "Frisk, Frisk, wake up! FRISK!" She felt... something, but she was too focused on the boy to think about herself. "W-what's going o-on in h-here- Oh my-" there was the sound of a clipboard clattering to the ground as she knew Alphys had seen Frisk. "Please, help him!" she pleaded, turning to look at the stuttering yellow lesbian dinosaur scientist. She was surprised when she realized Alphys was not looking past her at Frisk, but more...

at HER.

"Uhhh... Alphys? Unconscious hero of the Underground right there?" she asked sarcastically and walked out of the way of Alphys's path so she would not get that weird sensation of having a living being walk through their ghost. But Alphys's giant eyes did not stay on Frisk, they tracked her. She realized something was not right about that. Finally the royal scientist whispered something. "

C-C-Chara...?"

Chara's world collasped onto itself.
