Floating character model?

[Gojisaurus_Rex]

I was by myself playing with bots today and went into the enemy base when I saw a character model floating in the air paused mid-animation with a rainbow effect on it (not an actual player). I'm not super familiar with the game so I don't know who it is, what the animation is, or where the rainbow effect is from, but I took a screenshot of it so you can see for yourself. I wish I had more information to share but it was already like this when I found it. Also looking at the screenshot now I'm realizing that there's a beam coming out the side of the model going somewhere off-screen. I didn't notice it during gameplay unfortunately so I don't know where that's going.

Same thing happened again today. Here's the screenshot. Same spot but in the opposite base. Similar animation to the last one, so I'm guessing it's the animation for grabbing onto the ziplines? I don't remember what they're called.

A couple more times today, one of which was in spectator. I'm thinking maybe it's from characters trying to hook on to the powerline when there's a wall or ceiling in the way.
