Now im understand, Kris ain’t eat a moss.. He/She eat Chara algae. And thats also explain why Kris become Chara at the end.

More theories

This might be the best one I’ve seen

Yep

Best UT theory ever.

Wrong tbh kris is suffering from insecurities. She keeps a knife for protection not bloodthirst it's because she feels abandoned in every way abandoned by her birth parents, her adoptive parents and then her brother. That's how ralsie was made ralsie is an anagram for asriel because Kris made ralsie in a way who has no life without Kris so he is inable of abandoning him and he is so young because that's the asriel he wants to play with, the current asriel definitely changed he could be the actual angel demigod from undertale, the final boss. From the angels heaven.

2 things. #1 r/woooosh #2 That's just one of the many theories.

True. But it's more likely that he ate a plant then became chara, but who knows a flower can turn into a literal god of Time and space. Anything is possible

It's less likely*
