>>122662096>I figured it wouldn't be typical either way, probably some sort of advanced usagepretty much, a lot of Fionna's "mid-series" upgrades would be working along those lines, overall the rough direction for Fionna's forms(because I'm a huge nerd who watches way too much Tokusatsu);
>Base FormMagical Warrior Princess Fionna
>Basic Upgradesform changes using single Trinkets
>2nd Tier UpgradesStrengthened Bonds Forms(essentially using two or more Trinkets together through some sort of connection they have, a "Bubbline" form would probably be the first to be unlocked)
Self Incarnation Forms(several special Trinkets Fionna acquires that represent her past incarnations and alternate timeline versions of herself/Finn, that she can use for forms)
>3rd Tier UpgradesFamily Unity Form(Lady Rainicorn, Charlie, Viola, Jake Jr, and Bronwyn's Trinkets all used at once)
Elemental Unity Form(PB, FP, Patience St Pim, and Slime Princess's Trinkets used at once
Self Unity Form(using all the Self Incarnation Form trinkets at once)
>4th Tier UpgradesZeldron Unity Form(utilizes both Zeldron's Armor and a special Trinket containing some of her essence she hid in anticipation of the Sorcerer Queen's return, is able to use other Trinkets to form weapons)
GOLB Unity Form(the obligatory Evil/Berserk form, yes this is a REALLY bad idea)
>Final FormMagical Eternal Ooo Queen Fionna(unified power of all Trinkets, ultimate power has been achieved)
>Bit dark, hopefully they don't mind living vicariously through her or somethingFionna's ultimate form is essentially
her channeling ALL the trinkets at once, essentially practice for her ultimate destiny as Queen of Ooo which will involve permanently merging all the Trinkets into herself and unifying all their souls to ascend to a living goddess
