User blog comment:BigChill493/What Classic Ben 10 aliens would you like to see in UA?/@comment-2041110-20100818172719

I read somthing here on the wiki that Dwayne planned for XLR8 to make an enventual comeback on UA sooner of later so looks like your going to see that happen. That and I hope they reveal a couple new aliens shown in the original series like Xylene and Technorg's species.
