Killer T Cell Flag - Cells at Work! はたらく細胞！

The Killer T Cells Flag from Cells at Work! はたらく細胞！has a black field.  The logo is a white hexagon outline, and within the hexagon is a circle, and further within is a capital letter T in white that touches the edges of the white circle.

Some White Blood cells advance to the Thymus for special training operations, and can earn the T-prefix in front of their name.  It's like getting a college degree, and white blood cells can specialize in different kinds of martial-defensive arts.  You can think of the Thymus as being the Pentagon/West Point Academy of the human body.  Not all White Blood Troops cells are admitted into the Thymus Academy.  Likewise, not all cells that matriculate to the Thymus Academy, are able to graduate.  Because it is a rigorous training program, and some T-Cell Cadets do wash out.  In fact, if they do not pass their exams, they are forced to commit jisatsu. 

The most popular type of white T-Cell is Cytotoxic T-Cell.  In the show Cells at Work! はたらく細胞！the T-Cell is depicted as a lovable, over-aggressive, roid-raged, toxic masculine persona.  These type of toxic masculine cells are the kind you want kicking the ass of would be dangerous elements in your home base body.  You can't pussyfoot around germs, infected cells, and deadly bacteria—they need to be executed quickly, without hatred or malice.

Infected Cells are Zombies-normal cell left, infected cell right

To the left we are in the Thymus, where a group of T-Cells in black are getting trained to kill the germs.  Further in the background is a B-Cell practicing with his anti-body gun.  B-Cells do not engage in hand-to-hand combat like T-Cells.  Instead they are the archer/artillery of immune system that can soften and kill the bad guys.  Behind the Plasma B-Cell is a Helper T-Cell that acts as a coordinator for the Department of Immune Defense.  Helper T-Cells are a critical part of the administrative portion that do not take part in cellular combat, yet direct and coordinate activities for the grunts and snipers who do the heavy lifting.

Infected cells are portrayed as zombies, which is a perfect analogy.  Since a good cell basically becomes a turncoat baddie, but often explodes to  releases more virus head caps, which try to infect other cells.
