Crisis/Villain for Desmen(Son of a Herald)?

I'm having writers block Again >.< so I might need a little help.
In the next chapter-set of "Son of a Herald" Desmen will be going on a mission to Earth,accompanied by Nova and Quasar to investigate some kind of threat on Earth.Problem is,I can't figure out what that threat should be.
 
 
Desmen is a Kree who was raised by Silver Surfer,living and training with the Inhumans.He has a small portion of the power of Cosmic inside him and uses Kree devices to channel it. 

So I would like to hear your ideas.I've seen others make similar threads to this one so I hope Y'all can help me out.
