Paraby

Parabies are a type of swarming enemy that Samus encounters in Metroid: Samus Returns. They typically stay in one location and only move to attack if Samus disturbs them. While the swarm can eventually be wiped out via standard cannon fire, the Lightning Armor can be used to bypass them completely and take minimal damage in doing so.

 * "Parabies are small bat creatures that always flock together in large swarms. Their small size makes them a nuisance, but defeating them can net you a lot of resources. Turn on your Lightning Armor and melee-attack them to make short work of the pesky creatures."

 * ''"These creatures always flock together and generally mind their own business. The biggest threat they pose is by obstructing your way. Touching them deals damage, but they never pursue you.

Their most useful and interesting quality is the amount of health, Aeion Energy, and ammunition they drop when defeated. Defeat them quickly by using a melee attack on them with the Lightning Armor active. You can plow through a swarm of these enemies in one or two melee attacks and come out with more Aeion Energy than you started with. These enemies offer a great way to refill your resources when Recharge Stations aren’t available."''
