Do these guys seriously get three profiles? Kaiju, mecha, and a guy. Leif is really hogging the scenery.  

Space Vikings as a species are mostly human. Somewhere along the crazy course of history, some vikings journeyed to the stars, and in the midst of space, they became giants. Since the definition of a Kaiju in Tower City is “anything that is slightly bigger than usual… like 6’4’’ or something”, then Space Vikings are officially Kaiju. 

Biologically, they are the same as humans, but just in a larger scale. Their strength is utterly ridiculous. Their bodies are practically peak human health, adjusted for size. They are better than us in every way, well, except for intelligence.  

Space Vikings are really stupid. They worship a pile of dust which they believe is their immortal god king. They like to talk to their weapons and treat them as if they were living people. So much so, certain weapons have reputations for their attitude, which seems to be mutually agreed upon by multiple Vikings. Their entire culture can only be described as a shared psychosis. One can only wonder how they attained their technology. Perhaps it was pillaged from other alien civilizations, or passed down over time, their source forgotten.  

Despite their lack of intelligence, they seem to have a superficial appreciation of higher pursuits. They apparently have universities, theater, and arts. They all revolve around murder, but that doesn’t mean they aren’t a multifaceted people.
