Xenar

The Xenar (Ex-in-are) are a species of bizarre scorpion-like creatures that roam the wastelands of Spontanous-Combbust, the cyberpunk dimension.

Creation
The Xenar were created along with SpontanousCombbust. This was back when the dimension was made of deserts and forests, before any species other than Xenar, Gulls, and Ghouls had arrived.

The creatures populated the deserts around the edges of Spontanous-Combbust, but when humans (these ones evolved from wombats) arrived, they turned the deserts into a giant scrapyard for all their garbage.

Evolution
Even with the massive change of lifestyle, the Xenar managed to adapt to the wastelands. They became scavengers, but if a human came near, it was easy for the Xenar to kill him.

Day Of The Ancients
Bob's team of Fire Princes and Princesses arrived in Spontanous-Combbust and met the scrap scavenger, William Graham. Graham guided them through the wastelands, and they fought one giant Xenar.

Eventually they arrived at the portal, but they were intercepted by Time. Time used his powers to send some of them back in time to the deserts. It was here that Graham had to battle an entire colony of Xenar with only a log.

Luckily he was saved by Bob, who took him back to the current timeline.
