So this would essentially be Blaze post Loona saga.
Blaze is the quiet type. Talk first. Try and reason. But in a few instances, that isn't going to work. And when that happens? Usually a mistake. Not on Blaze's part, but on that of whoever isn't listening. And with the ability to manipulate soul flame... you better be careful.
Funny enough if I had to rank Blaze with power... Sukuna from Jujutsu Kaisen would be where he probably stands. Especially since Blaze can warp and bend his flames similar to slashes and cuts. So combined with the intense soul melting heat? Pretty fitting.
