Simple trophy that can be obtained with any character and a stasis missile. Using a stasis missile freezes your opponent and makes them suspended in air and you can knock hit after hit on them and it all goes towards the same combo.
Alternatively, if you are a God at this game you can choose any character and do a combo to get the amount needed by your own skill.
Kratos, Dante, Raiden and Nariko are good choices to easily obtain this.
