X2 is in love with the Martian Queen whom he serves. He considers Duck Dodgers to be more of a nuisance than an actual enemy. It appears that he doesn't have a mouth (case of point in "Duck Deception" and "The New Cadet"). He and Dodgers have worked together a few times in the series.
X2's backstory is currently unknown. However, he was born on July 24 and is aged 20-21 years old.
X2 is very quiet, intelligent, sly and evil. He can be very funny and cheeky at times. However, he only does good things in the sake of his planet or queen. X2 hates space bats, and any giant insects. When he first met The New Cadet, he was scared of her when she threatened him. X2 is most terrified of heights.
Marvin was employed by Martian Queen. He loves her, but she stabbed him in the back completely. Sometimes she is sweet with him, other times she mistreats him. He does evil frequently, but carries out jobs for the queen. In his spare time he sings, does clay work, cleans up his house + ship, sleeps, sits in a sauna, or walks his dog K-9.
