|~ Psimon's amused responds when Superboy tells Miss Martian to defeat him|
Psimon is a villain in the TV series Young Justice.
At Bialya, he and a team of soldiers investigate a technical object called 'The Sphere'. The resulting energy alarms the Justice League who send the Young Justice team to investigate the cause.
After arriving at Bialya, Miss Martian enters the tent the Sphere is located in. Despite Miss Martian being camouflaged, Psimon senses her and telepathically contacts her. Through her connection to the rest of the team Psimon manages to enter the mind of all of them and removes their memory of the last six weeks. In the resulting chaos, the team seemingly disbands and is hunted down by Bialyan soldiers.
After most of the team have found themselves again and regained their memory, Miss Martian infiltrates the compound once more only to be sensed by Psimon again. He tries to attack her again but this time, she manages to fight back. The two battle each other inside Miss Martian's mind. While this happens, the captured Superboy realises that Psimon's mind is absent. He wrenches free and Miss Martian manges to bring back his memory. While Superboy takes down the soldiers in the vicinity, Miss Martian and Psimon continue their psychic battle. Reassured by Superboy, Megan manages to defeat Psymon. The resulting explosion destroys the tent and throws back Psimon.
After the group has escaped, Psimon contacts the Light to reveal that Superboy and the Sphere escaped. However, the Light assures him that more tech will be delivered to him.
To ensure that Queen Bee can legally infiltrate the neighbour country Qurac, Psimon is sent to Qurac to mind-control President Rumaan Harjavti into joining the two countries and stepping down to Queen Bee. Wile the Young Justice team infiltrates the presidental palace, Miss Martian sets out to find Psimon. Psimon forces her to reveal her true martian self to him, devastating her. To hide her true self from her friends, she brain-blasts the entire group but Psimon reveals to her that he recorded her transformation. Once more, he invades her mind where he confronts her over her true appearance. He invades the deepest part of her psyche, torturing with images of her friends looking at her true form in disgust. This enrages her enough to stand up to Psimon, throwing him out of his brain and breaking his psyche in return.
