Character concept

This character would be either a duelist or a strategist. They have high damage, be long ranged and low health and there abilities would be a shield and dodge kinda like star lords dodge but here is the catch. His primary attack does your opponents entire health bar of damage no matter how much health they have but leaves them on one hp and he can't kill them he only can leave them on one hp but to compensate he only has one health and one ammo in his attack and the attack takes 3 seconds to reload. His ult would be an insta kill attack to anyone in its radius but takes a long time to charge up like Scarlett witches. As of what character this would be I have no idea but it could be a character original to marvel rivals. Do you think this would be broken or not?
