Seidlitz

Origin
Seidlitz was a strange red creature of unknown origin that left the circus to work with the criminal known as Dascomb Dinsmore. The two of them were theives and were brought to justice by Blue Beetle and his sidekick, Sparky.

Seidlitz possessed great strength and agility, at least rivaling that of a gorilla. He also ran on his hands like a gorilla, and did not seem much smarter, but he was capable of speaking English. He seemed to do something like parkour, but was also fine just smashing through things. Apparently, he had a weakness for lollipops.
