Can assist or metronome be used for exclusive moves?

I was going through YouTube, and while I was doing that I found an odd video of Wailord using Darkest Lariat. It’s highly unlikely for that to be possible, but it did get me thinking. Let’s get a more likely Pokemon to use other moves, like Skitty or Purrloin. Both learn Assist.

Let’s say you get into a random encounter, and only have a Purrloin and an Incineroar. You make your Incineroar forget moves until it only has Darkest Lariat, and Purrloin down to Assist. If Purrloin used Assist, could it turn into Darkest Lariat? How about Metronome? Is it limited to specific Pokemon? If it does work, would Z-Assist Darkest Lariat be Incineroar’s special move or just dark z-move.

Metronome (without using normalium z) can call any move that isn’t a z-move and isn’t on the list in the source. This means it can’t call the following signature moves, but can call all other ones: chatter, freeze shock, ice burn, relic song, secret sword, sketch, techno blast, v-createsourceThese are the signature moves that assist can’t call: chatter, king’s shield, mat block, sketch, spiky shieldsourceZ-assist only calls the type z-move, not the signature z-move.source
