Bat

Bats are flying mammals (the only ones in the real world, in fact). Associated primarily with Black mana, Magic's bats tend to be fearsome and dangerous, a stark constrast to the harmless tiny insect-eating flyers from our world (although those do exist on the Multiverse, such as Dakmor Bat). More often than not they are associated with Vampires.

The first card to bear the creature type Bat was Vampire Bats in Legends.

Innistrad Bats

On Innistrad vampires can change into bats which have such clarity of hearing that simple sounds become symphonies. Stensia is pestered by undead Marrow Bats.

Mirrodin Bats

Grimclaw Bats patrolled the Mephidross. Once Mirrodin became Phyrexia, they were compleated.

Ravnican Bats

Bats in Ravnica are primarily associated with the Orzhov Syndicate. Unlike other bats, which are primarily Black, these bats, specially the Blind Hunters, are mostly equally White as well. They are used as assassins and messengers.

In the Return to Ravnica block, and especially Gatecrash, the Dimir seem to have acquired bat-motiffs, such as in the architecture and the design of their Horrors. However, no true bats have been seen yet.

Ulgrothan Bats

Sengir Bats accompany the infamous Baron Sengir, the vampire lord who rules the Dark Barony from Castle Sengir.

Vampire Bats

The classical Vampire Bats are titanic flying creatures that may be used as steeds, for example by Kulrath Knights. They occur in Dominaria and Shadowmoor, as well in a few other planes.
