Manticores are mythical beasts that emerged in Persian literature. Manticores have a lion’s body and a human’s head and are generally quite fierce. Manticores supposedly ate people, but I just consume information. I was inspired to represent myself with a manticore because of an excellent Web comic called Darwin Carmichael is Going to Hell. The above image is from this strip specifically. I find it amusing and thus have co-opted it as a personal mascot.
If you are here looking for actual information about manticores, as I have learned that some people are, I recommend checking the Medieval Bestiary or John Guy Collick Dot Com.
