your signature move

Iron Head

My team as a gym leader (and champion) would have a few Pokémon know this move and I'd give it as a TM if it ever became one.

Metronome. It's unpredictable and wacky to use.

Slack Off

Worry seed

 

[Okido]

As a Trainer, my signature move would probably be Trick Room. I tend to specialize in very slow and bulky Pokémon, and I like to use lots of strategically timed tricks in battle to catch the other side off-guard.

As a person, my signature move would be Chilly Reception.
"The user tells a chillingly bad joke before switching places with a party Pokémon in waiting. This summons a snowstorm lasting five turns."

Taunt
Me and my friends really like pulling each other's legs in conversations, so Taunt is the perfect fit for me lol
