Tesera

Tesera is Riker Navy, a ranger created by Royal Pain Bee and Right Hand Turbulence. She serves as the Riker Rangers Second in Command.

The Riker Rangers were ordered to attack the kingdom of Sandar, destroying the Sandarangers' Gouri Hawk and Gouri Pike before the Kagarangers arrived. The two sentai then worked together to defeat then. However she and Hunter went after a weakened Naoki when the others formed Enomu Gattai RikerOh against Stag Gattai Gouri Rider (which used Houou Blazing Boomarang to defeat it)

After their defeat, they were arrested and fiercely interrogated by Eltar to find Zharen, Bee, and Turbulence.

Tauro had brought her up to replace Myosei in Day 39, meaning the Riker Rangers are serving a life scentence.

Personality
She is tomboy, but is also very gitty. However, this does not translate into her skill as she was able to cause Naoki to untransform and kill him with her ignatta.
