Idk, here's a list you'll forget:
His main power is Apocalypse, he can summon any major disaster, mainly fire rains and meteor rains
He is good at melee combat, and also summons the Apocalypse Sword, a dark red sword capable of dealing much more damage than you think it might do, just a cut on your hand can make you bleed out quick.
Overall, he also has two power i mentioned before, Ultimate Power and Ancient Power.
Ancient Power is just like the power of the greek gods, a massive amount of power that can be concentrated in one specific ability, like Zeus Lighting. In this case Fire.
Ultimate Power is similar but very distinct. It is weaker but in the hands of an Ancient Ultimate God, it is destructive, and he is specialised in Apocalypse.
You already know what Ancient Powers can be but Ultimate powers:
This is a list of Ultimate Powers, all of them are translated in English cause they are originally Greek:
-Death(Thánatos)
-Life(Zoi)
-Light(Fos)
-Darkness(Skotádi)
-Peace(Eiríni)
-Chaos(Cháos)
-Teleportation(Tilemetaforá)
-Apocalypse(Apokálypsi)
-Infinity(Apeiro)
-Nature(Fýsi)
-Timeless(Aiónios)
Etc etc
Ultimate powers are powers above the normal elements, and yes Death, Shi and Mors can learn the power of Thánatos, Life can learn the power of Zoi, and Peace can learn the power of Eiríni
Traveler did learn the power of Tilemetaforá, but he wasn't a ultimate god
Learning an ultimate power does not make you an ultimate god, you are learning the power of the gods designated to that power
