Notice the ball of light around his feet. This is to give the impression of directional speed, so I have incorporated this in the White Blood Cell and the Virus Fighter. I have not included this for the Mothership as it is large and barely moves, and when it does, very slowly.
The White Blood Cell:
In the animation, these will change size and move with the ship as it turns and pivots. This also goes for the Virus fighter.
The White blood cell is blue for a heroic shine, and the virus is read to show the opposite.
