Fern

* Fern
* Green Knight

— Fern.

## Summary

**Fern the Human**, formerly known as **Grass Finn** was the result of Finn the Human's Grass Sword and Finn Sword merging into one being. As he was recently brought into existence, Fern initially thought of himself as the true Finn, before he began taking on his own personality as Fern.

His memories are those of Finn's, so he goes through somewhat of an identity crisis after it's pointed out to him he's not Finn. Fern lost his desire to be just like Finn, but now he sees himself as a better version of Finn. Despite this, he still thinks of Finn's memories as his own.
