Minions are a character of a film that we all might have seen several times since the release of the movie Despicable Me. The first part of the movie was released in 2010 and later two more sequels of the movie were found to be released due to the overwhelming response that this movie got.

The story includes an evil scientist who tries to get to the top on the list of the most evil villain in the world. Minions act as his assistance and work with him and help him to execute his evil plans. The minions are the yellow coloured small characters who have a different language to talk, though they brought a comic relief to the Movie they were the assistance of the evil scientist.

Minions are distinct in appearances and are found with unique features that separates them from one another. They are small in size and shape, differ in height from one another, they can also be differentiated with their eyes, cylindrical.

He was taken to the Monastery of Spinjitzu, where he was given proper training as a Spinjitzu master, so that he could save his sister and all other Ninjago. In the Monastery Kai acknowledges other Masters of Spinjitzu and with them he starts his first conquest to find all the four Golden weapons, the Sword of fire, Nunchucks of Lightning, Shurikens of Ice and the Scythe of Quakes.

Other than the physical characteristics and their appearance they are found to have some physiological appearance too. For example with a crack and shake they can be a useful tool in the dark as they work as glow sticks, can be very helpful while moving through ventilation ducts. They can also survive without oxygen as one of them is seen in the space without the oxygen mask in one of the movie.

The appearance given to Kai by the Lego was very interesting. He is mostly found in red attire, has brown spiky hair and always found to have a more focussed expression on his face. Being named the Red Ninja of Fire he was found to be very hot-headed, totally justifying his elemental affinity. Very capable of making careful observation when the need arises, he was often found to be overlapped with the emotions. Earlier he found it difficult to get along with other Spinjitzu master but later came to be friends with them.

Kai is generally found to use swords whenever he gets into a fight. He first used a curved blade to fight the Skulkin when his shop was attacked by them. Before it was lost, Kai preferred to use the Sword of Fire as his primary weapon, later switched to the use of regular katanas.

Later in the series he gets the Elemetary Blade which also allowed him to increase his elementary Fire skills too. Later Kai and his friends come into contact with the Techno Blades. He and his friends are also known to have a Blade that can destroy ghosts, Aeroblade.
