You will be better equipped to deal with this threat once Computress explains what happened. When you spoke with her she was inside DexLabs in Genius Grove.

You will talk to Computress in a moment if I remember correctly.
You will be better equipped to deal with this threat the next time you are where you are. Go on in.
Greetings. We have had an unprecedented event. Dexlabs has been burglarized.
DexLabs has been burglarized by someone other than Mandark. It seems that Fuse's minions impersonated Ben Tennyson's Echo Echoes and stole all our AmpFibian research. They were last spotted near the abandoned lab. You must return it!
Thank you so much for saving us all from the catastrophe you are about to avert. As I will have told you, Fuse's plan would have unleashed an entire army of Fusion Omnitrix Aliens with the replicating powers of Echo Echo. That is, ir you hadn't foiled his plot, as you are about to.
That is the abondoned lab you will have entered prior to your successful saving of the world.
