Using a powerup to change the character's sprite/palette?

I need some help

I am making a Masters of the Universe adventure style game and I want to start out as Adam but become He-Man when you get a power up. I want to be able to change the way the character looks while using the power up. Kind of like SMB flower power.

Thank to any and all responses!

I do not have an answer to this but was wondering the same thing. I was thinking maybe both versions would have to be in the same graphics file and maybe a change in the code to tell it which place to look depending on a variable. But I haven’t gotten that deep yet. Hope you find it or an update addressed this as it is common in games.

I am trying to figure this out as well if anyone has any ideas
