Angelic Sleipnir (天使スレイプニール tenshi sureipunīru) is an Angel enemy that appears in the Stories of Legend. It also appears in some event stages, including No Plan A, Conquer the Galaxy and Slimy Stallions.
Angelic Sleipnir has a very fast and fairly powerful attack along with high health, but moves slowly. He has a small chance to knock back your cats, making him very deadly against poorly-prepared setups.

Strategies
Try spamming Dragon Cat and other long range attackers, backed up with Macho Cat, Samba Cat and Wall Cat sent out one by one to temporarily stop Angel Sleipnir, as this horse has quite a far ranged and non-stop attack.
Do not bring Paris Cat, as she can't hit even once due to the shorter range.
