Well Chinook came up with this idea for a universe inhabited by some of your more classic B-Movie type aliens. Namely Martians and Venusians. I quite liked the concept so I went on and sketched me a character of each of the main species. I'll let them each tell you a bit about themselves. ^^

Zazz:
"I am a Martian scientist. I am proud of my people and my work. Some species have had it easy living on worlds awash in water and vegetation. Mars is a Harsh desert world. Thin air and radiation but beneath it's surface my people Thrive. I thrive. I invent and I build machines. My War Tripods are some of the best you could ask for and my ship work is second to none. Anyone who says otherwise is lieing for whatever reason. I'm the one to turn to if you want something done right."

Xon:
"I am Xon. I am a Martian Human hybrid. I work with Zazz as his assistant and bodyguard. I am proud to serve him. He has always been kind to me and the rest of us hybrids. We were created during the war between Mars and Earth as soldiers. Now during peace times many are unsure what to do with themselves. They lack a purpose but I have mine. To assist Zazz in his endeavors and better Mars."

John:
"I'm John. Captain John and well I'm the leader of this merry band of spacers. I try to keep on good terms with people but can you believ ethere are times when I have to shoot people? Yeah I know some people. Human, Martian, Venusian or whatever can still be jerks. I'm the glue that holds us all together even if Zazz tends to be condescending towards me. Ah well he's a useful little green guy. Don't tell him I called him little though. Heh."

Arel:
"I am of Venus. Beneath the clouds of our world are lush verdant forest bursting with life. Our cities dot the forest. It was some of our Early travelers that are remembered by humans as ancient gods. I myself am an warrior and healer though those two things may seem in opposition it is useful to know the later if your are the former. And do not listen to the Martian. The Forest has made us strong as well. It has also made us diverse. We come in many colors as do the flowers that bloom. It is in service of that beauty that I travel with these so that I might bring more knowledge home and protect it."

Well hope you guys liked the pic and info. ^^ Remember concept here is  chinookorca 's so credit goes to him for that. ^^
