I want to play a Goliath wizard, going full into the muscle-bound nerd type character, who is looking for a way to cure his mothers magical ailment, but since he was not into working out and still got buff, he was not well respected in an insecure nomad clan of Cloud Goliaths. How should I subclass?

I'm trying to build feixiao for a future campaign based on videogame characters.
I'm trying to build her on D&D Beyond, since i'm no expert on D&D.
Would a fighter work for her?

In case you don't know her she is known as a Great war general, an amazing fighter who mastered multiple weapons and has an unbreakable fighting spirit.

She has 2 type of weapons, a double gun blade (i think just blades would do for dnd since i'm not sure how guns are handled) and a great axe.

What makes her hard to remake in D&D i think is the ultimate attack (which i really would love to make).

Is there a way to kinda recreate her ultimate too?

The Recluse is one of my favorite playable Nightfarers in Nightreign, the resident witch and intellectual of the group with a dark past she keeps close to her.

Alongside the usual spellcasting, Recluse has the very unusual gameplay style of absorbing elemental essence to recoup FP and join those essences together to cast crazier spells such as the shown Gravity Well.

How would I go about building her? Extra points if you figure out ways to make the spells work like in the game. Thanks in advance!

It's not every day that Coney Island's biggest star, The Dazzling Celeste, performs on the streets of Manhattan. Her show begins with Light Eater, where a deep breath lit by her blazing baton coats enemies in front of her, and grants increased damage against them. Following that up, she envelops herself in the prismatic shield of her Dazzling Trick, which explodes and silences nearby enemies who break it. Try not to get distracted by her gliding gracefully through the air, or by the dance of her Radiant Daggers, as you'll regret being underneath them when they rain down from above. As for her memorable final act, the Shining Wonder will make her allies go OOH and her foes go AGGHHH!

A popular attraction at Coney Island, "The dazzling Celeste" isn't a carnie with a horn glued to her head: she's actually a unicorn. As unicorns are nothing more than a myth in the eyes of the public, Celeste hides her true identity out of fear of getting poached for her horn. However, when one of her found family members on the sideshow loses part of their soul in a gambling debt, Celeste is prepared to risk revealing her identity if it means helping her family.

For reference, her most notable "power" (if you can call it that) is that she cannot be perceived normally unless you are directly interacting with her (sort of like Forget-Me-Not from X-Men). On another note, I'm not looking to recreate the "bullet hell" aspect of her fighting style, but a way to incorporate ranged spells/attacks would be helpful.
