Mister Ninja is a slim humanoidal alien with grey skin. His body is covered with gill-like organs. He wears a black uniform with green and white stripes that almost covers his entire torso. He has a black and white mask with two holes revealing his eyes.
The Omnitrix symbol is located on the right side of his chest.
- Mist Generation- Mister Ninja is able to expel a thick mist from the gill-like organs all over his body to hide in. His large eyes are uniquely evolved to see through the mist with ease.
- Enhanced Reflexes- Mister Ninja has enhanced reflexes, allowing him to react much faster than most other species.
- Adaptative Combat- Mister Ninja’s instinctive combat prowess makes him extremely adaptable in just about any fight. He can change up his fighting style with a moments notice.
- Weak Point Detection- Mister Ninja has the ability to identify all pressure points on any living being within about a minute of looking. This helps him in a fight and makes it pretty easy for him to end a fight quickly.
- Raw Strength- Mister Ninja is not exceptionally strong, making it hard for him to overpower opponents. He has to rely on his skill set to be able to topple physically stronger opponents.
- Mist Control- His mist can easily be dispelled by strong wind, and he must rest if he makes too much of it at once.
Vaporans were once a peaceful monk-like race that turned to a more ninja-like lifestyle when their planet was invaded by the Incurseans.
- Mister Ninja was unlocked by Ben shortly after he turned 17 during a training session with Kevin. His ability to disable opponents with pressure points led to Kevin being paralyzed for about an hour, much to his annoyance.
- Mister Ninja does not have bones and is made up entirely of muscle and cartilage. That makes him very flexible with almost no pressure points of his own.
