Professor Evil

Professor Evil is an A.I. that appears twice a week (used to be weekly) challenge in Bloons TD Battles Mobile and Bloons TD Battles Steam added in version 6.8. Every week, random towers, powers, and map are used. Upon beating him (now impossible) or surviving until a certain round number, you will get a certain number of medallions. The number of medallions alternates between 500 and 1000 and Fridays and Tuesdays respectively. Professor Evil's challenges are a great start for getting medallions for new players. The challenge usually lasts three days, and it takes about three days for the challenge to appear. He has 100,000 health, but you can beat him by surviving a certain amount of rounds.

Appearance
Professor Evil looks like a monkey with a black top hat, monocle, cape, and curly mustache. He may be comparable to Monkey Tycoon due to both characters sharing a similar outfit.

Strategies
Professor Evil is very aggressive. He will send huge rushes often. Since he is an A.I., he can send bloons before you can and has infinite money. He used to have 150 lives, like a normal player, but now is virtually impossible to kill him due to his large amount of lives. It is important to get a large amount of eco early on to defend his rushes. It is a common misconception that he sends bloons at certain rounds. He sends rounds at certain times, so stalling will not work against him. You should remember to use your powers when necessary.

Challenge Details
There are currently 120 challenges as of November 26, 2021.

Trivia

 * In the mobile version of Hot Air Bloon, there is a villain in the game that looks quite similar to Professor Evil in Bloons TD Battles Mobile. This may possibly be also him, but it is likely another character, Monkey Baron.
