Adventure Time: Lantern Corps.

***DOWNLOAD PLZ****
I got inspired to draw this after the episode "Lady & Peebles" aired. I've done a little research on the Lantern Power Rings and know what emotions power all the different colours and such, and I thought "PB showed the willpower to be deserving of a Green Lantern Power Ring" in that episode.
And thus an idea was born.
Finn is the Blue Lantern of Hope because, well, he's a very hopeful kid and he is the hope for Humanity itself too.
Peebles is the Green Lantern of Willpower because... what can I say? Her determination is INCREDIBLE! It was what beat up Ricardio the Rapist and what dragged 4 people - one being a 15ft horse - across the Ice Kingdom over 2 days. Imagine how much effort and willpower that must have required.
Also, we saw clearly how she overcame her fear of Ricardio and whooped his ass, making her the perfect choice for the Green ring.
She is pondering over the scientific technology in the ring.
Jake is the Indigo Lantern of Compassion because he is quite compassionate. The episode "Princess Cookie" serves as the greatest example. Unfortunately, I gave him a ring before I did my research on the Indigo Tribe, which use staffs. He is holding a HUGE BURRITO WRAP which he has just generated with the ring.
Marceline is a Yellow Lantern of Fear because she had the most control over Finn and Jake when they were still scared of her, and also because she holds a few fears herself.

Now, when thinking of the colours, I also thought about what the different colours mean to each other. Yellow is a weakness of the Green Lanterns due to Parallax, and the Yellow Lanterns are super-effective against them. This fits in pretty well metaphorically with the relationship between PB and Marceline - Marceline is a weakness, and PB is always edgy around her. Marceline is pretty much the only person we've seen so far to dig inside PB's emotional barrier and provoke her.
Blue Lanterns are good allies of Green Lanterns, and Green power rings can be, I believe, empowered by blue batteries. Finn is a STRENGTH to Peebles. He helps her deal with the kingdom's less political issues and saves it all the time. They're good friends.
I'm also sure that blue rings might just be super-effective against yellow rings, and Finn is no longer scared of Marceline, therefore yellow would be pretty powerless against him perhaps.
I know only what I've gathered on Wikipedia. I'm sorry if I've completely fucked up my DC lore.

Well, this took me a while and I can't anatomy at all.
