Plot
The Ones That Smoke in the Mist

Sonic is first seen in the series when he stole Leo's camera while he was visiting Dianne's diner. While Leo was chasing after it, they were caught in a gunfight between a criminal from the Alterworld and the police. The monkey then passed out from the shock from the ensuing event.

Later, the monkey along with Leo, was brought to Libra's base. Femto was later seen onscreen telling humanity that he was 'bored' and decided to play a little game to pass time. Then the criminal from earlier had his back torn open by a gate which spawned a demon. After seeing this, the group then turned to Leonardo and Sonic who looked at them, and a gate emerged, causing the top of the building they were in to be sliced off, and Klaus hurt when he protected Leonardo. When the gate that Femto put opened, everyone thinks that the monkey was the gate and tried to catch it. Chain went after it, but was only able to keep track of the monkey and wasn't able to catch it.

When Leo got the chance to kill the monkey and close the gate, He used his eyes, and saw that the gate was actually a flea on the monkey and crushed it. Femto was shocked by this as he was expecting that they would kill the monkey, which would have opened the gate, instead of closing it. After Leo unhook his camera from the monkey, he slumped back, the monkey holds up the camera as if handing it back.. and Leo sits up to takes it.
