Health bar over moving character

I have a prefab character in a 2D platformer and I want to display a health bar over it. This health bar is actually 5 different png images to represent 100%, 75%, 50%, 25% and 0%. The character is in constant movement and I want the health bar to follow it. Only one of them can be shown at a time depending on the health of the character.
What would be an effective approach to accomplish this task?
Best regards.

Simply make a plane with a Health Image Material and add it as a child to the character. Then switch out the texture of the material based off of a health variable.

Thanks! It worked
