The Lead Bloon is a fearsome opponent, with 120HP (60 hearts). It moves slightly slower than a Red Bloon. Also, it takes half-damage from sharp objects, like Shurikens or your trusty Diamond Sword. It takes x10 damage from explosives though, lure Creeper Bloons to it if you don't have TNT with you! Also, if you manage to pop it, you're greeted by a pair of Black Bloons. It is only found near lava or in the Nether. Overworld spawning is very rare, and it spawns in packs in the nether, particularly near its lava ocean.
