Cruel Angel Clionel (Angel)

Cruel Angel Clionel is an event enemy that appeared in an exclusive stage called Clionel Ascendant. It has the ability to slow cats and it can't hurt near Cats.

Enemy
One nightmare of a sea angel. Attacks rapidly as opposed to Cli-One, and has a chance to slow your units. Can hit between ranges 400-1200, meaning that no normal meatshields can survive. Instead, use Artist Cat.

Trivia

 * Quite literally a sea angel, a creature known for its grace, beauty and horror.
 * One huge reference to Neon Genesis Evangelion, specifically incorporating the wordplay from Episode 24: 「最後のシ者」 The Beginning and the End. The specific borrowed term can be read in three different ways, either as envoy, casualty or on the water's edge. Presumably this enemy is all three at once.
