Personality
Keeby is an extremely minor character, appearing with only a textbox many times, so almost none of his personality is known. His original personality was rather sarcastic, with a disliking towards Cloud, but it was changed to be much more cheerful and happy.

Role in Cloud's Forum Adventures
Keeby first appears in the 1st Chapter of the Soul Shard series, claiming that Redblaze is a "hot mess". He than appears in the 2nd Chapter of said series, saying that "this" can't be happening ("this", referring to Dark Cloud & FCN getting the Soul Shard). He doesn't appear again until Chapter 7 of the Soul Shard series, where he throws a hammer at Dark Cloud, to Dark Cloud's surprise. He appears once again in Chapter 10, being trapped by Zerospace, saying, "No..It can't end like this!!".

Keeby is completely left out of the Lunar/Spectral Battle Series for unknown reasons, including the end sequence where all the characters hang out on the beach.

Keeby finally reappears in The Yarn Adventures Saga, in Chapter 6. He has a conversation with Spectra about how everyone had already been kidnapped, than questions Spectra's specific mention of Cloud, before both of them get kidnapped themselves. He than appears in Chapter 7, testing out his parachute ability once finding out he's made of yarn. Than, in Chapter 9, he demonstrates how to turn into a rocket, than tears a hole in the Dark Cloud Yarn Mimic. In Chapter 11, he appears as a textbox, saying that Yarn is susceptible to fire. He doesn't appear again until Chapter 27, once again as a textbox. He once again does not seem to appear in the end sequence where all the characters hang out at the beach.

Keeby is mentioned by Kaiby in Chapter 13 of the Miracle Crown saga. Kaiby says he'll tell Keeby to track FCN's coordinates. Keeby appears in flesh in Chapter 15, saying the castle looks "cleaner" than he thought, before Cloud tackles the Miracle Crown, causing the scene to cut away from them. Due to the Miracle Crown saga's cancellation, it is unknown what would have happened.

Trivia
Keeby has two separate designs. The first was a gray Kirby with horns, but it was changed when Herobrine8219 changed his name to Keeby, and his design was finalized as such.

Keeby is said to have a more prominent appearance in the Miracle Crown Saga, wielding Grand Hammer. However, since CFA was cancelled, this is no longer likely to appear.

Keeby does appear in the CFA Reboot, with his original personality in tact.
