Icons over enemies
Icons over an enemy are debuff markers. Stunned means the target cannot act. The debuff page is the picture key, last touched in the research notes around February 2021.

The sourced answer
Other overlays named there include Halo of Spores, a damage over time, Training Montage with pause, prepare, and parry, Marked by Lizardfolk Tactics, Scatter Tacks, Ruby Brilliance, and Donaar's flee, fear, and drop. Stacks and colors change the same icon. Enrage is not one of those icons. Enrage is the fight getting harder because it lasted too long.
The Spanish page repeats this key for the icon search. New icons after February 2021 are outside that page, so I do not pretend the key is complete. Stack color still belongs to the same named effect.
FAQ
