Post-Apocalyptic Enemy (New RP)

After the events of Cyqua vs Mecha Doom, and the revival of most of the fallen (minus Alpha and Cy-K), your character notices that Cyber hasn't been himself lately, and has been seen gloomily walking through Green Hill Zone.
Cyber: ...*sighs, landing from flight and sitting beneath a tree* ...
What do you do? (Also, I'm back! XD)
