Tetra

Tetra, a character in the Endless Summer series, is a member of a group of soldiers called the Arachnids. He is first seen in Book 2, Chapter 9.

Appearance
Tetra is a big, muscular hit-man wielding a pair of mechanical fists and a high tech suit.

Personality
He loves to show off his strength but isn't very bright. He is also a coward as he freaks out and orders his men to shoot Quinn after she becomes possessed by the Island's Heart. He retreats after she destroys his mechanized fists.

In Craig's idol scene, Tetra is shown to be defensive when it comes to his own catchphrase, as shown when Craig muttered a quote Tetra considered rightfully his after he slammed the former against a wall in the MASADA complex.

He is shown to be guillible given that he believes that Quinn is still possessed when she makes simple hand gestures.
