A Monster from Mars has crash landed

Hello, I am... the Monster from Mars. *sigh* Yes, that is truly what I am called. It is my... hero name. I'm still not sure what the purpose of heroes are. They seem a bit redundant, as there is a police force, yes? What am I to think but that human police are incompetent? I've had (or will have) it explained to me that these villains... super villains, have powers that no one has that are even beyond my wildest dreams. I'll believe it when I see it.
And what powers should I combat them with if it's true? I have no powers. I'm just an alien on Earth.
My real name is Irax, but ever since I've gotten here, all I've been called is "Mars". I'll get used to it, I suppose. That's one downfall of not knowing enough English. Also, the air here is suffocating! And I feel so heavy here. I haven't been eating very much, and I feel rather ill... but I have to get used to it. It's impossible for me to return home, for more reasons than communication barriers, suspicion between species, and a busted ship. The reason I had to leave Mars is the same that I can't return.
I happen to have a pet. His name is Frederick. He's a tuna fish... fascinating creature. No one had better eat him. He's the only pet I have. No, he's not from Mars. He's just a regular Earth tuna, and I've heard people joking about eating him. Although I don't think they're entirely joking.
So, I have a bad-tempered picture of me as my avatar. And I have a tunafish in a goldfish bowl for my signature. I hope to have fun rping with you guys on the weekends.

Welcome to Earth! I hope you enjoy your stay. Keep away from England, they are known for torching a lot of aliens...

Meh... They mostly Torch Wood. xD you might wanna stay away from there to keep your fish from being turned into fish'n'chips however.
Welcome to our planet!

Thank you both for the advice. If I am sent to England for a mission, I could hardly help it, but otherwise, I shall do my best to stay away from that place, whether for their anti-alien policies or seafood snacking tendencies.
