Alexander's power is Cartoon Physics, though it's more restricted to the funnier of these abilities like the Squash & Stretch Effect (as shown by the frying pan), being able to stretch his body and create limited constructs (like a mallet head out of his hand, or pulling the skin on his arm back as if it were a sleeve) as a result, generating a cloud of smoke to "censor" physical fights, walking off platforms like there was still something under him until he looks down (or, as I call it, Gravity Doesn't Exist Until You Think About It Syndrome), and an abnormal amount of space in his pockets from which he frequently pulls abnormally large things out, like a baseball bat or cartoonishly-large first aid kit. This is just among a couple other things like steam coming out of his ears when he gets mad, or floating to safety by way of umbrella.
If acceptable, he'll also be able to break the fourth wall on occasion, and travel through various methods, from walking in pictures between frames (imagine that at the Louvre, or the Sistine Chapel ceiling) to jumping into a computer or television screen. (He may even be able to pull other people in with him, and things out with him.)
He's basically right out of a Looney Tunes skit, though I'll try and make it more noticeably based around Bugs Bunny and Wile E. Coyote. (The latter of which is more about absurd contraptions and ACME purchases.)
Also, on Cira's power, it's kind of simplified to just controlling motion itself. He can throw an object indirectly, direct sound waves, or stop/speed up a fireball, but he can't actually change anything else like the pitch of the sound or the size/intensity of the fireball.
