Notable Attacks/Techniques:

- Telepathy: Arguably J'onn's greatest power, his telepathy can easily shut down minds, alter memories, read the entire contents of a person's mind, read and affect minds on a planetary scale, communicate across vast stretches of space and dimensions, manipulate souls, and affect cosmic beings.

- Shapeshifting: J'onn has free transformation, he can change his size at will, stretch his appendages, increase or decrease his mass (although sometimes this requires absorbing nearby inert mass, like that of the ground of a planet), disguise himself as a human or other being, or an inanimate object, manipulate his body for more effective attacks (such as increasing the size of his lungs for more powerful breath attacks)

- Martian Vision: J'onn is capable of projecting destructive beams of energy from his eyes, these generally aren't as powerful as Superman's heat vision, but they can do formidable damage and are very accurate. They can also be used passively to scan targets with sensory powers.

- Linear Vision: An obscure ability that allows J'onn to resist time manipulation and reality-warping to an extent, and also protect his allies from it. However, it requires a great amount of concentration and energy and he can only keep it up for so long.
