How did Slowbro use more than four different moves in a Tera Raid Battle?

Question

It was very weird when I encountered this.
When I was tera-raiding with a few people against a Five-Star Steel-Tera type Slowbro
I took the time to identify the move it has.
One was Liquidation, Curse, Water Pulse, and Yawn.
Four moves. But suddenly. It comes right at me with a Zen Headbutt.
No joke.
Five moves? Something ain't right.
Is it rare for this kind of thing to happen?

And if anyone wondering if I caught the Slowbro. No. It wiped me out.

Can you somehow prove that it really happened, possibly by showing us a screenshot or video?

I don't have any proven evidence of it because the storage of my switch is filled up so I can't really record. That and the Slowbro wiped me out.

I know what I saw. I just need to know is this common for most Tera raids

I know that in SwSh, certain raid Pokemon could have more than 4 moves as a way to make them more difficult, including events like Mewtwo as well as most legendaries in Dynamax Adventures. With SV, it feels like they were trying to increase the difficulty ceiling for raids, so I wouldn't be surprised if 6 and 7-star bosses have more than 4 moves.

If caught, the Pokemon go back to only knowing 4 moves.

Answer 1

Tera raid Pokemon have more than four moves as shown in this video. The same is said in this reddit post

I literally just encountered this with a 5 star gengar, it used shadowball, sludge bomb, confuse ray, spite, and hypnosis

Just encountered a 5* Flapple With Dragon Rush Dragon Breath Dragon Dance Grav Apple Grassy Terrain Iron Defense And Trailblazer

The 5 star houndoom I encountered used Taunt, will-o-wisp, sunny day, howl, crunch, and flamethrower.

Those are just the top three replies to that post I linked

It is like Dynamax raids but without Dynamax moves and is a diferent gimmick
