Guts from Berserk. He has a skill set you can easily addapt to be a good hero. And he is just a badass character.
Dragon Slayer (Bronze): He attacks with his sword and deals xx Damage. The force of his strike shakes the ground, letting near by enemies stagger.
Repeater Crossbow (Silver): He fires a salvo of arrows for 6 seconds. Each dealing xx damage (would be a mix of Savages and Cinders skill. The flat shooting from Savage but with the tempo of cinders bombs)
Berserker Armor (Gold): Whenever his health drops below 10%, he gains 100k health, 1500 attacking Power and 1000 armor for 10 seconds. While Berserker Armor is active his life drains by 15k each second (the numbers are just examples)
Smoke Bombs (Platinum): Whenever he gets effected by a negativ status effect he throws smoke bombs at all enemys, dealing small damage (~10k on level 70) and dissorientating them for 3 seconds, to hide is vulnerability.
His basic attack would be bolts from his mechanical arm.
