How do I stop my iPad from wrongly auto correcting my name?
I'm not sure where you entered your name incorrectly.

If your name is entered incorrectly as a contact then:


Click on Contacts
Scroll down until you see 'Alien'
Click on the contact
Click Edit
Change the name


If you entered your name incorrectly only in your email account settings:


Go to Settings > Mail, Contacts, Calendars
In the ACCOUNTS section, click on the account that has the incorrect information (e.g. Gmail)
Click on Account
Change the Name associated with that email account.
