Den is not well known on Thundera and there's a good reason for that, he has been on an undercover mission on Plundarr for 7 years how? You may ask is that possible, you see Den has a unique ability. He has the power to shape shift into anyone he wishes, including mutants. His orders are to gather all the info he can, while throwing a monkey wrench into their work. Sabotage ladies and gentlemen, that's right, sabotage is his middle name more to come on this guy a little later.
