To answer your question, we need to define what you mean by "super form".
Here are some examples:
* Super Saiyan (Dragon Ball): A higher power level achieved by Saiyans. Super Saiyan God and Super Saiyan Blue are more powerful forms than regular Super Saiyan.
* Super Mario (Super Mario Bros): A power-up achieved by consuming a Super Mushroom. Super Star and Super Sonic are more powerful forms than Super Mario.
* Ultra Instinct (Dragon Ball): A state of heightened awareness and reflexes, surpassing even Super Saiyan Blue.
* Forms in other fictional universes: Many stories have their own versions of "super forms", such as The Flash's Speed Force, Hulk's rage-fueled transformations, or Superman's solar-powered boosts.
Therefore, the answer to what is more powerful than "super form" depends entirely on the specific fictional universe and the "super form" being discussed.
To get a more specific answer, please tell me which fictional universe and "super form" you're referring to.
