How do I make a smart bouncy ball

Im making a game where the MC can become bouncy at will, and I want it to be like, he is standing still and a projectile comes by, on impact both ricochet in opposite directions, how can I make this? I tried to use the bullet behaviour but the constant need of an angle of motion makes it annoying for my limited event capacity, I also tried playing around with phisics behaviour, but the guy just wont bounce, the projectile rotates its motion in a weird way and then leaves, even tho the MC's inmovable value is no, he still refuses to move, any ideas or working events you could suggest?

someone? I got the behaviour of knockback when getting hit by a projectile, but I cant get it to correctly bounce against the floor

Although you probably understand exactly what you have explained above, for someone who hasn't seen it it is very unclear..

Could you share your capx and/or make some kind of drawing of the effect you are aiming for?

well, I cant give the capx, Ill try to explain further

its a game where you dont fight back with violence, but rather sneak out and deactivate drones peacefully

when an enemy spots you, he shoots a laser bolt at you, if you toggle your shield, you will acquire the laser bolt's angle of impulse and half of its impulse, thats fixed, but I cant figure out this

I would like for the player to be able to solve puzzles by bouncing with the shield, its a bubble shield, so when you deploy your shield you wont bounce, but if you collide against a wall at a speed, you will bounce off that wall, like a bouncy ball, I tried using the bullet's ricochet behaviour, but since it requires an angle of motion, it gets annoying to control

Any ideas?
