Gladiator Bloon

Gladiator Bloons are bloons introduced in BTDS. They are high-healthed and very fast, along with having a shield that needs to be broken before you can hurt them. To top that off, they're immune to damage for three seconds after being hit for the first time.

Strategy
They're DANGEROUS. They can easily spoil any good defense. However, there is one major flaw with their ability: It activates when hit, not when damaged. This means that, despite their lead property, their ability can be triggered by anything. A good strategy is to ave a cheap tower at the front set to to strong to cause the gladiator bloons to trigger their ability before reaching your main defense, wasting its potential. Try Glue Gunners or 0+/0+/1+ Super Monkeys.

Trivia

 * Regrow Gladiator Bloons won't retain the temporary immunity when they regrow
 * However, they will have the shield. Due to this, the regrow leads from a regrow gladiator take 3 seconds longer to regrow than normal.
