“How many time should I tell you this, you don’t need to gift us Mxyzptlk,” Batman said, getting more than annoyed by the imp’s insistence.

“He’s right,” Superman added, “we don’t want your gifts, especially after what you did last time.”

“What, what did I do? You never trust me,” the small excentric imp answered with a shocked expression on his face while flying around the two heroes.

“First, you almost created an international financial crisis when you caused millions of peoples to win the lottery” the man of steel answered.

“or when you created walking buildings because you granted some stupid wishes so peoples could have a river view apartment?”

“Oh come on, I just tried to be nice and help the others! It’s not my fault if humans made so many stupid wishes”.

“And that’s why you want to give us these things?” Aquaman said, holding suspiciously a small blue crystal set into a thin golden chain. “It’s not really my style Mister Mxipt… Xmilt, erh…”

“It’s Mister Mxyzptlk, M.X.YZ.P.T.L.K. Look it’s easy, just repeat after me.” A large blackboard suddenly appeared in mid-air, the imp pointing each letter with a stick like a first-grade teacher.

“And why should we accept these gifts?” Batman said, trying to distract Mxyzptlk before the Atlantis ruler made him regret this prank. The imp stopped, he didn’t even notice Aquaman’s rising anger. Flying toward the table, he grabbed another crystal.

“Because I want to be good for once, I want to help my favorite superheroes fight the monsters, the invading aliens and all the baddies. With these crystals I crafted from the fifth dimension, you’ll be unstoppable, gaining powers beyond your imagination. It’ll make your job easier, trust me!”

“I don’t need superpowers,” Batman cut him off.

“And I have enough myself, thanks,” added Superman.

“Oh come on! Just try them for a few days, it’ll be synchronized with your inner desires, so it won’t do anything you wouldn’t want. I even have a few more for your girlfriends or whatever you’re into,” Mxyzptlk said, acting like a door to door seller.

“No, sorry mister Mxyzptlk but we’re not interested, that’s final.”

“I can’t believe we are wearing this,” Superman said as he fiddled with the red crystal hanging on his chest. “At least it’s not kryptonite.”

“I must admit he is a good seller,” Aquaman answered, wearing a blue, saphir-like crystal.

“I don’t want to talk about this,” Batman groaned, a dark crystal hanging on his chest. “I prefer to know these are in good hands instead of god knows where, he could give these to anyone.”

“I don’t feel different, do you think it will really increase our power?”

“I don’t have superpowers and I don’t want them,” Batman answered.

“Being a billionaire is a superpower,” Aquaman said as they left the Watchtower. “And if they really work as intended it could be a great gift.”

“With Mister Mxyzptlk, anything is possible,” the Man of Steel said.
