I'm looking for ways to play specific characters that I'm unable to find builds for. For now, I'm looking for a way to play as Necrid from Soul Calibur 2. Any suggestions?

For Soul Calibur characters most would be Fighters, Barbarians or Paladins. Maybe a Hexblade or Bladesinger. 

You'd be human variant or custom lineage. 

Everything else is pure flavouring / roleplay. 

Necrid, as somebody who manifests weapons on the fly, might be a better fit as a Hexblade than other classes. (Though it still doesn't really fit. Since it costs an action to manifest a weapon, you can't constantly change it like Necrid does. There are many things from other fiction that just can't be done without home brewing in D&D, and a somewhat smaller set that just don't work at all.)

Since he's green I'd go half-orc.

I don’t know necrid, but if he is manifesting weapons/blades and changing them on the fly you might consider psiwarrior.

 Or hexblade warlock.

Homebrew is welcomed, as long as it's accessible through DnD Beyond 

I'm looking to make a new character. I'm think half elf drow. 4 lvls eldritch knight and the rest in abberent mind sorcerer. 8 str 15 dex 13 con 10 int 10 wis 15 Char. Before modifiers. Thoughts?

 Reborn works for Necrid as well
