Computer Bugs are the antagonists in System Defender and also the main antagonists in Level 1 of the game. There are 3 different kinds: red ones which attack in large groups, yellow ones which move fast, and purple ones that can take lots of damage. There are also boss bots that are larger and can take more damage than normal bots. There are also centipedes of doom, which is a bunch of boss bots together in a row, which only appear in Herbert's levels.
