People always thought that the Kaiju Skinmites that fed off the blood of the Kaiju were harmless. But, the reality was that if one of them bit you, it would inject some of the blood into you. This was the result. 'Were-Kaiju'was a mutated Kaiju form of the Jaeger pilot, Mako Mori, after she was bitten by a Skinmite. It took a week to find the cure for her. Her Kaiju form may look frail, but it is still quite dangerous. It has a powerful bite force that can tear through metal, including that of Jaegers. It is also incredibly fast and agile.
The Were-Kaiju may look frail and weak, but it really isn't weak at all. It is actually fast and agile, making anyone mutated into one of these a deadly foe. It has a powerful jaw that can tear through metal and steel, including that of Jaegers.
Mako's mutated form bares a startling resemblance to a mix between Gollum and the Xenomorph from Alien. She even has the ability to shoot spikes from her back to attack opponents.
