Half Super Monkey, half killer robot of death. Shoots from 2 guns at once!
Robo Monkey is the 3rd upgrade of the Super Monkey for Path 2 in Bloons TD 5. It costs $7650 on Easy, $9000 on Medium, $9720 on Hard, and $10800 on Impoppable. It can fire regular darts, Laser Blasts, or Plasma Blasts from both of its guns, depending on first path upgrades. Each gun is capable of targetting independently, making it especially effective for tracks with multiple paths. Occasionally, it can shoot at two completely opposite directions, one example being when a Robo-Monkey is shooting at Lobby. Because it can shoot with two guns at a time, it is also stronger against MOAB-class bloons than a regular Plasma Monkey.
In terms of power, two Super Monkeys are less than a single Robo Monkey, since each projectile of the Robo Monkey has an increased popping power by +2 (+4 in BTD6, so 6 for the base Robo Monkey, due to how Epic Range now grants +1 pierce on top). One major difference besides popping power is that Robo Monkey's arms are now alternating depending on the right arm's setting: First/Last or Strong/Close. The Robo Monkey is additionally more cost-effective, costing less than two separate Super Monkeys and with its exclusive benefits, could prove more useful in certain situations.
3 Plasma Robo Monkeys can pop an entire Z.O.M.G, including its children, on every track up to Mount Magma.
Upgrading a Super Monkey to a Robo Monkey also gives it an additional range boost.
Robo Monkeys have more pierce than normal Super Monkeys. In fact, Robo Monkeys have 2 extra popping power than normal Super Monkeys.
If a Robo Monkey is placed in the correct position of a track with multiple paths, its arms will target independent paths.
When you fast forward, it looks like the monkey shoots 2 bullets from each cannon and the bullets are further from each other "at the cost". This is same for the Technological Terror.
For some reason in BTD5, Robo Monkey can pop Frozen and Lead Bloons bloons even without the Path 1 upgrades. It still shows as if the Robo Monkey is shooting normal darts though. This is no longer possible in BTD6.
