Omega is a boy created by the Director in Germany. He has an anatomy 400% stronger than a regular boy, with more efficient muscles and bones.
While in Germany, Max is forced to out-smart and out-strength Omega. He seems to be much stronger and more intelligent than Max. When Omega appears to be winning a race to and from a castle, Max uses her flying abilities to cross the finish line first. The Director immediately claims that she cheated by flying, but Max defends herself by insisting that it isn't her fault that Omega is stuck to the ground.
When everyone begins to battle, Max faces Omega. Jeb advises her to move quickly, as a flaw of Omega's is his inability to track fast things. Max distracts Omega with her superior reflexes, and then kicking or punching him while he is not attentive. Omega is eventually defeated.
