They call themselves the... Guardians of the Sword Coast.
I've been playing the Guardians of the Galaxy game lately, and after realizing how similar Lae'zel and Gamora are, I know I have to reinstall BG3 for a Guardians playthrough.
STARRING...
Tav as Petyr O'Quill, a.k.a. BARD-LORD - Half-elf, dual crossbows, high Cha/low Int. Torn between Lore for Cutting Words, or Swords for more pew pew.
Lae'zel as Gamora, the deadliest woman in the galaxy Sword Coast - All I really need here is modding her an emo haircut.
Astarion as Rocket - They're both foul-mouthed and quick to anger. Their backstories actually have a lot of thematic similarity, being twisted into someone else's weapon. Probably a Sorc to accommodate Rocket's love of explosions, unless the Artificer mod is any good. Could have Shovel as a stand-in for Groot? I may try to mod him into a gnome so that he too is small and adorable.
AND MAYBE...?
That leaves one party slot, which I see going one of two ways:
Karlach/Minsc as Drax the Destroyer - Big, gullible, excitable, destroys stuff.
Minthara as Nebula - I feel like she'd have the same vibe in a good party. Dragging her around with the misfits I'm turning into begrudging heroes might make for great banter.
Suggestions on builds/mods/things to do for maximum chaos and therefor fun? Stories of your own weird themed parties? Arguments about my awful flarking decisions?
I'm now imagining Jeff Goldblum as Gale and I kind of love it.
We're reaching for characters at this point, but I suppose we could cast Shadowheart as Moondragon and Wyll as Adam Warlock for the lols if nothing else.
You might be onto something with Halsin & Groot... could rotate between him and Minthara until Minsc is available.
