I'm Marco. Just Marco, that's it. You don't get a last name from me. It's not that I don't want to give it to you, I'd love to tell you exactly who I am, where I live, my phone number, etc. But I can't. It's too risky. See, there's these alien slugs called the Yeerks...they could be anyone, even you, because they wrap themselves around a person's brain and take control. So you can understand why I'm hesitant to give you the information they'd need to kill me.
I'm not totally helpless, though. Another alien, an Andalite named Elfangor, crash landed in a construction site my friends and I happened to be walking through. In an instant, my life changed forever. Thanks to Andalite technology my friends and I can morph into any animal we can touch. That's our gift, and our curse. We can fight the invasion, maybe save the world, but if we stay in morph more than two hours, we're stuck forever.
Any questions? Ask, and if I can answer, I will.
((OOC: I'm gonna run this account like it's taking place just after they so any questions that take place near the end of the series will likely not get answered, sorry.))
