Bats

What it looks like

The Bats is a Common card that is unlocked from the Builder's Workshop (Arena 5). It spawns five very fast, single-target, air-targeting, melee, air troops with very low hitpoints and very low damage. Their deployment is in a star formation. They resemble small, dark purple bats with glowing blue eyes, fangs, lilac underbellies, and pink ears, snouts and wings. They are also the same as those spawned by the Night Witch. A Bats card costs 2 Elixir to deploy.

Trivia

• The Bats resemble the in-life bat species called "Desmodus rotundus" (common vampire bat). The common vampire bat is a hematophagous bat species that primarily feeds on the blood of livestock, which is done by biting their prey while they are sleeping. In Clash Royale, Bats attack in a similar way by biting their enemies.
• The Bats are 1 of 17 troops that inspired a troop in Clash of Clans, the others being Spear Goblins, Bomber, Skeleton Barrel, Minion Horde, Firecracker, Battle Ram, Ice Golem, Zappies, Baby Dragon, Giant Skeleton, Ram Rider, Inferno Dragon, Miner, Royal Ghost, Ice Wizard, and Night Witch. It is the only troop from Clash Royale that is only available as a sub-troop in Clash of Clans.
• The Bats are tied with Skeletons and Suspicious Bush for the lowest hitpoint of all troops, with 119 hitpoints at Level 15, and 32 hitpoints at Level 1. Guards also have the same hitpoints, however, they come with a shield.
• The Bats are one of the first troop cards to receive a card render, alongside the Archers, Knight, Goblins, Bomber, Skeletons, Barbarians, Royal Recruits, Skeleton Barrel, Rascals, Musketeer, Giant, Valkyrie, Wizard, Flying Machine, Hog Rider, Royal Hogs, Dart Goblin, Zappies, Elixir Golem, Baby Dragon, Skeleton Army, Witch, P.E.K.K.A, Prince, Balloon, Giant Skeleton, Goblin Giant, Hunter, Electro Dragon, Wall Breakers, Bowler, Cannon Cart, Mega Knight, Ram Rider, Miner, Royal Ghost, Ice Wizard, Magic Archer, Bandit, Lava Hound, Night Witch, and Fisherman.
• The Bats are 1 of 9 troops that have the same sprite for both players, the others are Skeletons, Electro Spirit, Fire Spirit, Ice Spirit, Heal Spirit, Elixir Blob, Phoenix, and Lava Pup.
• Even though the card spawns 5 Bats, the card render displays only 4 Bats.
• The Bats are 1 of 4 troops which can defeat themselves in one attack, the others being Skeletons, Firecracker and Wall Breakers.
• The Bats has been featured in multiple special game modes outside of the card. More specifically: The Bats are 1 of 23 troops that have been featured in the Troop Rush game mode, the others being Skeletons, Skeleton Dragons, Fire Spirit, Elite Barbarians, Firecracker, Rascal Girls, Royal Hogs, Heal Spirit, Elixir Golem, Guards, Prince, Balloon, Golem, Wall Breakers, Ram Rider, Sparky, Phoenix, Royal Ghost, Bandit, Lumberjack, Santa Hog Rider, and the Monk. The Bats are 1 of 3 troops that have been featured with an Invisibility buff, the others being Goblins and Skeletons.
• The Bats and Skeleton Dragons are the only troops which have been available outside their card before they were released as cards. In the case of the Bats, they were available as a spawned troop from a Night Witch.
• The Bats, along with the Skeletons and Royal Recruits, are featured as a sub-character in Squad Busters.
• The Bats are the subject of a few Emotes.
• Before the Bats' card release, the Bats' count was decreased to 4 (from 5). Despite this, the card's description had an error, mentioning that the card would spawn 4 Bats, despite spawning 5. This was addressed later when they lowered the number of Bats to 4 on 12/6/2017, in the June 2017 Update.
