Does the face mask have properties when on or off could anyone shed light?

Yeah I was just wonder what difference the face mask has when on or like more damage or reduced speeed so detail would be much appricated thank vega players new and old school!!!

No claw = makes Yun seem strong
No mask = makes Akuma look like he has a shitload of life

complete opposite of reality but its the thought that counts

I don’t know about the Yun thing, but Vega does have the lowest vitality in the game with no mask. Kyo has a 100% combo on him with no mask.
