in the campaign i'm trying to revive, i have a giant titan for each element.

they are part of the story, and they are too give the Player characters special powers, that are earned.

fire, earth, water, wind, nature, ice, thunder, light, and dark.

ignatios, quakearos, titania, breeze, packson, chill, bolt, glowmoria, murk.

(names are a work in progress)

i would like some advice on what powers they should give, and personality tips for the titans, but here is what i have so far

earth(looks like a gorilla) and fire(looks like a skinny dragon) are often fighting.

water (looks like a mermaid, and acts royal) and thunder (humanoid shaped lighting) care for each other

nature (looks like a giant wolf chimera) looks after light( looks like a 6 winged angle) like a little sister

ice (giant ice tortle) is calm and wize

wind (green gargoyle) is split into four smaller ones each with a different ruling emotion

dark (three headed eldritch abomination) is childish, is evil and loves misery, and chaos

light is always fighting dark to stop the chaos, and mayhem

and feel free too suggest more elements for titans

and all of them are god-zilla sized, except breeze he is in 4 smaller pieces.

I don't know if you want to differentiate between the two, but 5e has separate elemental damage types for Lightning and Thunder damage

Thanks.

I might add a titan.
