Fluttering

The Fluttering is a Heartless that appears in Kingdom Hearts 0.2 Birth by Sleep -A fragmentary passage-, Kingdom Hearts Union χ, and Kingdom Hearts III.

Design
A Fluttering is a cross between what appears to be an umbrella and a bat. Flutterings tend to hang upside down instead of materializing like other Heartless.

Strategy
It is vulnerable to all magic and melee damage. When hurt enough, Flutterings starts spinning like tops. Parrying them is impossible unless Guard is used.
