I have built a character inspired by escanor. I went with titan mauler, + summer rage power + pride drawback, + sun blessed character trait, + giant blooded character trait,+ potion of enlarge person, + +3 elysium bronze butchering axe with called, quenching, growing, and furious, + elemental blood powers, elemental rage powers. He took power attack and exotic weapon proficiency butchering axe.
The titan mauler at 15th level can enter a titanic rage which acts like enlarge person, however because it is a Su power it will work with the spell or potion of enlarge person. I also had him take the pride drawback, giant-blooded and sun blessed. Although the lesser version of elemental blood and elemental rage both do the same thing and need swift actions in order to activate, I got them because the ore powerful versions are what I needed. My version he hailed from Irrisen, on the day of his birth the elemental plane of fire leaked into the realm, giving the character ties to a fire giant.
