My Idea for him is a gentle giant human boy who's always a peace keeper of Ooo and is a big kid / teenager who's alway loves adventure and is the perfect giant-sized boy of Ooo at 50ft or 60ft tall. He's got Jake The Dog's shapeshifting abilities (Mostly Size-Shifting) and is also able to expand his clothes and other stuff when growing.
Finn's always have Jake and BMO by his side and are his family as well. They lived in a Treehouse and have fun things to do. He sleeps outside when he's giant as well as hugging them like cute tiny dolls. He's also very gentle and kind despite being righteous and heroic, he can get into trouble especially being clumsy while stepping on buildings and knocking on city streets and other places in Ooo.
Including The Candy Kingdom witch he tries not to wreck it all the time due to his loyalty to Princess Bubblegum and his friends like Marceline, Lemongrab, and Simon. (Ice King Formerly) He's got his real arms as well as his normal outfits.
He's also very shy and naive due to him being a big giant human as well as being mocked at by some as a freak but He does his best to ignore those nay sayers and does what he can to be a hero.
Finn's also very playful and is very cute childlike person with a Big heart of pure kindness and is very ticklish as a giant in Ooo. He's also able to Grow and Shrink his height and can shapeshift into anything Including his Body Parts.
Finn The Human as a giant is my Idea for an AU / Fanfics. I just love him as a giant so much because his cute design works great as a big boy. He's also soft and pretty. I love him a lot as a character. I love Adventure Time as a whole.
