Not sure of the definite name for this AU, but I’m using “Gravity Gems” for “Gravity Falls cast with Gems” and “Crystal Pines” for “Steven Universe with the Gravity Falls cast”. Gets hella confusing otherwise.
Dipper-Agate (weapon: bo staff)
Mabel-Apatite (weapon: manriki)
Dip/Mabel fuse-Blue Lace Agate (Dipper being dominant, weapon: chigiriki)
Author/Stanford-Onyx (weapon: throwing knives)
Grunkle Stan/Stanley-Obsidian (weapon: brass knuckles)
Stanley/Soos fusion-Celestite (Soos is dominant until he looses his temper, then Stan rears his head and Tokyo is destroyed)
STORY: Fugitives Onyx and Obsidian, two Gems close enough to form a near-permanent fusion, are split as they attempt to escape Home World and crash into Earth; Obsidian landing in Oregon and Onyx going MIA. Though devastated at losing his other half, Obsidian’s grief is stopped short at realizing he’s landed near an active Kindergarten; after disposing of the few guards and others, he finds a Gem created there–Angelite. After realizing the new Gem could be of use to him, Obsidian takes Angelite under his wing and the two shut down the rest of the Kindergarten, finding two Gems crawling out of the same hole.Taking them in as well, Obsidian makes it his task to train the three Gems in the nearest human town, Gravity Falls, and also prepare to search for his brother Gem.
I’ve always seen Steven and Soos as eerily similar, from the Jesus indications to their appetites to their natures, so this seemed like the natural choice for me.
The two are HELLA bubbly and are just as similar as Soos and Steven. Plus Amethyst’s clashing with Pearl makes me think of the (few) clashes we’ve seen between Mabel and Dipper. With that said, it’s pretty obvious that…
The same obsession with planning, for one. For another, he’s more likely to be polite and formal than Mabel is.
BONUS POINTS IF HE’S A FUSION OF BOTH STANS
It just FITS better like this because hey, Garnet has gauntlets, Stan has brass knuckles; Garnet’s the levelness of the team, Stan’s the well of common sense and reality when the Twins or anyone else aren’t.
