Ideas for four different Giant Kings?

Greetings. I am currently trying to expand my roster of Giant Kings with a new one of each type. The reason is simple, I loathe playing with generated rulers, much preferring the narrative depth and/or thought out builds that premade rulers provides. However with the just 3 giant kinds that came with the DLC alongside the ones I have made myself I only got about 2 of each type.

Unfortunately I am currently struggling with coming up with ideas for more. Currently just got a pretty solid idea for the Fire giant, one inspired by the DLC's key art leading a clan of underground dwarves, as well as about half an idea for an underground stone giant.

If any of you have any interesting builds or cool thematic giant kings, feel free to share them. And even if not, just share your giant kings. I need inspiration and is not picky. Thank you in advance.
