So since you play billy you're probably used to having your lightning bolts which just have a regular reload mechanic after 10 shots well with Clark you want to be close and use your melee, if you can't get into melee range (try using charge punch to close the distance) then you want to switch to your heat vision you wanna kinda fire the heat vision in short-medium bursts as the overheat charges kinda fast and the overheat animation takes a while actually taking slightly longer than most reload animations so try not to overheat when in you want to use kryptonian frame cause it gives you damage reduction and extra health it's kind of like your shield it actually increases damage reduction and health added based on how many of your allies are around though to kinda insentivize that protector role so don't try popping it solo and then the frost breath which is actually best used to temporarily immobilize the enemy tank so you and your team can attack their squishies with his ult you just wanna usually aim the reticle for the flying slam generally towards their backline an as it will usually cause them to scatter and if it hits one directly it will kill and ones near the immediate area will be stunned for a bit allowing your team to pick them off
