Apparently a lot of people think that the red aura that Argos makes during the fight is the effects of thermo fist fighting style.
If you imbue thermo fist as warlord into Argos’ weapons visual of the attacks might look like it but actually it’s not.
The aura that Argos make is coming from the weapon itself.
The proof that it’s the weapon making aura is:
Exopolis Dodge reflex
Charging Energy holding the weapon (yeah there’s a lot of things going on there since im a savant but you can see the red tint of weapon charge)
The Argos fighting style is unknown since he practically never used it.
Even though I think it’s the basic fighting style since he only trained his muscles in his description written in the Order of Aesir tab.
Argos’s fighting style is supposedly called “Brute Strength” and is red as that’s the aura imbued on his halberd and lance.
But you are correct in assuming that it isn’t thermo fist, as thermo fist would’ve inflicted burn and I’m guessing that brute strength is the evolution of basic combat
