With the release of this new mechanic, I feel it's fair to write down a list of how it works and interacts with other agents. If any of these points are incorrect, let me know. I got most of these things from Ryan Central's stream.

There are two suppression effects:

• ZERO/point: Suppresses enemies for 8 seconds and it is a single pulse in a 15m radius. Works through walls and tells KAY/O what enemies were suppressed. Sticks to enemies.
• NULL/cmd: Suppresses enemies for 4 seconds and it is five pulses in a 45m radius. The ultimate itself lasts 12 seconds, so each pulse occurs at these breakpoints {0,3,6,9,12} seconds. Works through walls. It does not pulse while KAY/O is down.

What does it do anyway? If the pulse hits the enemies, it prevents them from using abilities and affects some of them as they are being used (I'll explain below). I don't know all the ability names by heart, so for the sake of clarity, I'll do something better :)

KAY/O, Breach, Brimstone, Omen, Astra, Reyna, Phoenix, and Sage utility is not affected after its cast. Additionally, for the following agents, if the utility is not mentioned, it is not affected.

Notably, passive skills (Jett's hover and Phoenix's heal) are not affected.

Cypher and Killjoy utility (except ultimates) is revealed and disabled.

Skye and Sova minions are killed.

Raze and Jett "weapon" ultimates are disabled momentarily; remember that Raze's lasts 10 seconds. Sova's ultimate is disabled as well and likely won't be able to be used at all since it has a short duration.

Notable Reyna interaction: During her ult, while the auto-heal works, she can't dismiss away since it's a cast ability.
