Leapers strongly resemble Hoppers in advanced state of decay and bleeding at the neck, yet possess at least doubled health. They deal the same contact damage and typically hop around blindly, but have a better sense of where Isaac is than Hoppers. What makes Leapers different from Hoppers is their ability to leap high into the air and land near Isaac's position, firing four blood projectiles in a plus pattern when they hit the ground.
Unlike Hoppers, they will not change forms when they touch a Fireplace and will take normal damage.
Eternal Champion Behavior
Eternal Leaper acts similarly to Eternal Hopper, it takes longer to start jumping, but will fire tears in "+" pattern every time it lands. It also shoots 8-way bullets everytime it lands after the big jump.
