Evokers are considered illagers, which means that they are 'hostile outcasts from villages'. They look similar to villagers, except their skin is gray instead of brown, and they don't have a unibrow. Evokers are found inside particular rooms of the Woodland Mansion, one at a time. They may be accompanied by 1-3 Vindicators. As of 1.14 - Village and Pillage, evokers can also spawn as wave 4 and 6 of Raids, sometimes riding a Ravager.
Evokers are hostile towards players, villagers, and Iron Golems within a 16-block range. One of their attacks summons tiny hostile pixies called Vexes. Their second attack spell summons several clamp-traps from the ground in either a ring or a long line, depending on their target's distance.
These clamp-traps, known as Evocation Fangs, are evoked in either a 20-m line for distant targets or an inner ring of 5 fangs with an outer ring of 8. They deal damage upon snapping shut.
Evokers will flee when attacked if not in the middle of casting a spell.
Evokers can be dangerous when ignored, so you have to prioritize killing them first instead of the Vexes they summoned. Any weapon can be useful in dispatching evokers, though swords can be more useful in combat as Evokers need to be prioritized first.
if you see them waving their hands in the air that means the evoker is attacking. If its looking at you immediately build a 2 block high tower so the evokation fangs dont bite you.

This is a reference to the video game Age of Empires where the priest unit would convert enemy units to their own side while uttering "wololo".[1]
While summoning a Vex, an Evoker raises his hands and emits gray swirls above its head, as if under the effects of a Potion of swiftness.
The evoker was originally going to wear a white hood similar to that of the Illusioner. This can be seen in Meet the Evoker. (This hat model was also going to be used for witches and several villager types.)
Evokers are still present in peaceful mode, but they flee from players and don't attack them.
