Godstrike

You can get this and Domination  together but if you're having a rough time without any abilities, you can easily do them separate as well. 

The boss you do this on will depend on your skill level but personally I found the 1st boss, Tutoriaal, to be the easiest to do this on. You need to make it through the entire without taking a single hit of damage. If you're not stacking this with Domination, you can do this in Arcade and stack up on defense abilities (dash, shields, etc). You may need a few practice rounds before you get it but as soon as you've defeated a boss without taking any damage, the trophy will unlock. If you need a visual reference, please see the following video that shows this and Domination  being earned together against Tutoriaal.
