1) Biologically Viltrumite. This is only apparent on a sub-cellular level; otherwise, he looks human. Physically, this gives him all his powers.
1a) Consequently, Mark is insanely powerful. He survives massive amounts of damage, can fly to the Moon in about half an hour (holding his breath), and punches through things on a regular basis. However, much like Superman, he can't really lose control of his abilities, only his emotions (see 4).
1b) Things Mark cannot do: See, hear, smell, taste, or touch beyond the normal level of human senses (barring things like being able to react to things while moving at super-speed). He will not hear your heartbeat, smell your fear, etc. Mark does not have heat vision, super-breath, or the ability to fly backwards or forwards through time. You're thinking of that Other Guy, with the Spitcurl.
2) Intellectually and emotionally human. Mark is, for all intents and purposes, an 18-year-old teenager from suburban Southern California (and from what I've seen, it doesn't get much more suburban than Riverside). He suffers from the foibles and failings of the average American teenager. You have been warned. Mark is also not stupid. He's an above-average high school student, with a A- average. He won't be winning the National Merit Scholarship, but he's no dunce.
3) Mark doesn't curse. Canon doesn't say why, but he just doesn't. (The strongest words he uses, normally, are "Jeez" and "Darn.") If he curses, it means he's lost his temper (see 4) or is otherwise emotionally distraught.
4) Mark has a temper. It's a durable thing, but when he loses it, somebody gets hurt. In canon, the deaths that he has directly caused, with his own hands, come from him losing his temper. This is, I think, an element of Viltrumite physiology, since almost every Viltrumite seems to have something of a battle rage.
5) Mark is 5'11, weighs 175 lbs (most of the time; there's some indication that his weight changes when his invincibility kicks in), and has blue-gray eyes and black hair. His full name is Markus Sebastian Grayson. He hates his middle name (it's his mother's grandfather, who died before Mark was born).
6) Mark is a cult TV and film fanatic and comic book geek. His favorite movies are zombie films, and he's just on the cusp of the zombie craze that we're still experiencing. (The Zombie Survival Guide will be published in about four months in his world.) If your pup is from a cult TV show, Mark might recognize him or her (I'll ask before posting anything). The only exception to this is "Star Trek." The Trek franchise does not exist in Mark's world; that subculture ended up following other shows, like "Science Dog."
