Sub-Bots

Sub-Bots are enemies in Zero Deaths. Before the events of the game, there was a war involving them. PewDiePie must destroy bots to get Monetization Coins.

There are three types of Sub-Bots. Red Sub-Bots and orange Sub-Bots are on the ground while green Sub-Bots can fly and shoot missiles. Orange Sub-Bots can only be destroyed with the epic 399 smash attack.

Trivia

 * The first cut scene shows a sub gap (presumably between PewDiePie and T-Series) at -399,999,999,999. This implies there are roughly 400 billion sub bots.
 * The art by Peet Cooper, however, only shows the sub gap at -399,999.
 * In gameplay, the sub gap is at -399,999,999,999,999 (a 15-digit number), giving an approximate number of sub bots of 400 trillion.

Behind the scenes

 * The sub-bots are a reference to accusations that T-Series uses sub bots. In the game, however, T-Series is never mentioned by name, although the letter T appears in various places to symbolize the enemy.
 * Originally, T-Series was planned to be the main villain of Zero Deaths.
 * Due to the abbreviated subscriber counts on YouTube, giving the subscriber gap in exact numbers as is done in the game would be impossible in real life unless the abbreviation of subscriber counts is removed by 2033.
