Verti-Cal and Horizont-Al

Verti-Cal and Horizont-Al (Cal and Al respectively for short) are among the craziest beings in the multiverse. When they first appeared, they were notorious for their fun-loving ways. In the Zone from which they hail, practically every law of physics is pure rubbish. They can make virtually anything happen, and do so for fun. Then Operation: EndGame happened, and they argued with each other about whose fault it was for allowing their zone to be affected. This led to a devastating war.

First Appearance
Sonic's bad day was beginning when he attempted to grab an unusual cluster of Magic Rings, and was catapulted into their zone. Sonic encountered Verti-Cal and Horizont-Al while trying to figure out his location and orientation. Initially thinking they were Dr. Ivo Robotnik's cronies, Sonic had an incredibly tough time keeping up with them as they kept letting their reality go wonky. Realizing this misunderstanding, Sonic fell out of the Zone, and landed back in the Great Forest, where Antoine found him and asked him "What's up?" Al and Cal watched Sonic angrily chase Antoine for asking that question at such a lousy time. (StH #2)

It didn't help that according to an explanation of Al and Cal's zone, there are no real laws of physics. There is no up, no down, and no telling how that curveball will curve. When Sonic went on a freakish journy guided by the Ancient Walkers, he thought this trip reminded Sonic of Al and Cal's ditsy dimension (StH #4, #35)

Later activities
Then Operation: EndGame occurred, and the Ultimate Annihilator caused numerous effects to happen to numerous zones. Al and Cal were nearly destroyed when their zone was reduced to near-nothingness, but they survived and restored their zone. Unfortunately, they blamed each other for allowing this to occur, and had become warmongers out to destroy each other. When Sonic and Tails accidently got sucked into this zone, Verti-Cal and Horizont-Al decided to let them decide the outcome of the war. Horizont-Al brainwashed Tails, while Verti-Cal enslaved Sonic. With their pawns now outfitted with armor borrowing design elements of their current forms, Verti-Cal and Horizont-Al let their minions duke it out. Tails had superior fighting skills, but Sonic stopped Tails's tails with his staff, and nearly killed Tails, had they not both chosen that moment to snap out of it. Sonic and Tails tried to talk some sense into Verti-Cal and Horizont-Al, nd the two thought breifly about the idea of becoming freinds again, but nixed that idea. Sonic and Tails managed to flee from the zone leaving the outcome unknown. (StH #59)
