sigh..
I've made a topic like this before.
after 2 years? haha jeez.
Stick to words that mean a lot to you.
or pop out your school books and look in them
preferably your Science books.
If you have a good vocabulary mentality level, then you'll know what you need.
google some scientific names, like elements and compound names etc;
they're all pretty eye catching and sound like Pro names.
You can look up Spelling Bee champion words and find some crazy and cool words.
Google is your friend.
I use it and it works 99.9% of the time, don't come to MPGH first, some kids here are assholes.
I do agree with them though,
Xao whatever is too much on the asian side and you'd be called an anime freak or a kid with a small asian wiener .
Decepticon on the other hand is too nerdy, like a little kids name after he watched Transformers the movie yelling "Megan Fox, MEGAN FOX"
I prefer the classic Transformers up to Armada, everything after that somewhat including the movie sucks.
