Mobar

Mobar can use its action to polymorph into a Medium bat-humanoid hybrid, or into a Large giant bat, or back into its true form, which is humanoid. Its statistics, other than its size, are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Mobar has blindsight out to a range of 60 feet as long as it's not deafened.

Mobar has advantage on Wisdom (Perception) checks that rely on hearing.

Mobar can take the Disengage or Hide action as a bonus action on each of its turns.

While in sunlight, Mobar has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.

Due to poor depth perception, Mobar has disadvantage on any attack roll against a target more than 30 feet away.

In humanoid form, Mobar makes two scimitar attacks or two shortbow attacks. In hybrid form, it can make one bite attack and one scimitar attack.
