Popokarimu

Popokarimu is a bat-based B.O.W. produced by Tricell, Inc.. Popokarimu is a boss fought in Resident Evil 5. It resembles a large mutated-overgrown Bat with an insect's thorax as a tail with several legs attached to the tail. This is probably the result of gene splicing done on a bat. Its entire body is extremely resilient, only the fleshy underside of its tail is vulnerable to the player's attacks.

Attacks
Standing upright, it resembles that of a scorpion, its shell protecting it from gunfire. Likewise, it attacks as such. Along with a charge attack, Popokarimu has a body slam as well as the ability to take flight. While in the air, attacks are virtually useless unless one attacks its vulnerable tail. It also has a sticky substance that can come out of the back of its tail so be careful.

Appearance
Popokarimu appears twice throughout Resident Evil 5, once in the Mining Area, and again in the Caves. In the Mining Area, a cutscene of a Majini driving a steel-plated truck is shown. The truck crashes, killing the Majini, and blocking the path to continue, and Popokarimu jumps out of the vehicle. In the Caves, the Popokarimu flies down from an opening in the ceiling of the statue room.

Strategies
When Popokarimu is on the ground chasing the players, use a Proximity Bomb to stun it. While it recovers, have both Chris and Sheva attack the fleshy underside of its tail. Repeat until defeated, and take note that it may fly up into the air, rendering the Proximity Bomb useless until it has returned to the ground. Note also however that shooting it's bat body will also still damage it, albeit at a much lower rate compared to it's weak point in the tail. This should only be done if one has plenty of ammo to spare as not shooting it's weak point is an expensive affair or only a few more shots are needed to put it down.

If attempting to keep away from the Popokarimu in the Mining area, don't resort to using the little sheds containing items for cover, unless a small amount time is needed to heal or reload. A single swipe is enough to cause the sheds to collapse. It is generally easier to run from it to gain some room as it's not that fast of a mover, even while flying. But in an emergency, throwing a flash grenade at it will stun it long enough for one to get far enough from it.

When dealing with the Popokarimu in the Caves, dodge its attacks and run up the stairs. Before long the button mashing sequence will appear, requiring you to run away. Defeating the second Popokarimu without running away will grant the player the 'Soul Gem' treasure.

Three hits with an infinite rocket launcher during the first fight is very effective, while two hits in the 2nd fight will kill it swiftly. In my experience, 1 hit usually gets him down and out. Alternatively, aiming for the head in both using the Rocket Launcher (either version) without stunning it will usually kill it in one shot.

Popokarimu takes reduced damage from shotgun shells (around 40%) so use a rifle or a rapid-fire machine gun while it is stunned.

A grenade launcher can be found shortly before you fight the second Popokarimu. A few direct rounds will stun it leaving it open to a barrage to the tail. The grenade launcher should have enough ammo to kill it on normal. On veteran or higher you will still need to use other weapons. WARNING: Be sure not to get too close when firing the grenade launcher as its splash damage could severely injure you. You can also kill it by using flash rounds in your grenade launcher, it takes about 12-13 direct hits to kill them. A faster and cheaper way to dispose of them.

Trivia

 * Popokarimu can be translated to Caring Bat.
 * It took Capcom three weeks to come up with the design and another month to create the in-game version.
 * The English version of Resident Evil 5 spells its name as "Popokarim" in the Figurines section of the Library.
 * If the player chooses to stay and fight the Popokarimu in the caves instead of triggering the quick time event, it drops the extremely valuable Soul Gem, which can be sold for tremendous amounts.
 * This creature bares an uncanny resemblance to a Mutalisk, an alien creature from the Starcraft series. This is especially noticeable when the Popkarimu is airborne. However, this similarity could be due to the Popokarimu's elongated insectoid tail. It is far more likely that the flying animations were taken from the Monster Hunter series, another game developed by Capcom (all flying monsters have the same idle flying animation where they tuck their tail under their body, just like the Popokarimu).
 * The squeaking noise it makes is the same as the noise made by the marionette enemies in Devil May Cry.
 * Popokarimu is the second bat-based B.O.W. boss in the Resident Evil series, with the first being the Infected Bat from Resident Evil Zero.
 * While trying to kill the Popokarimu by shooting it anywhere but the fleshy underside of the tail is usually futile, the S&amp;W Model Model 500 can slay it with 5 - 6 shots to the head.
 * This creature appears in Resident Evil: The Mercenaries 3D as a main boss in level 3-5.
 * Unlike RE5, firing at the head with a Rocket Launcher in Resident Evil: The Mercenaries 3D won't kill it.
