A ground type could withstand any electric attacks, but if it knows water moves, that could put my teammate at risk. Perhaps the trick, then, would be a dual type, either part water to neutralize any potential water type attacks or something suitably defensive, such as a steel or dragon type...

[Given the options here, however...]

Ultimately, Courier Six-san or Emporio-kun strike me as solid allies in such a matchup. Though, on further reflection, that Pokémon also features lamprey-like qualities...

[Though, that's getting off track. He shakes his head, then continues...]

Flying resistance rules out grass typing. That narrows it down to rock, steel, or electric, but I find the latter two highly unlikely.

[So it's winding up for an attack... Akechi makes a little diagram in his mind, running through possibilities.

A punch? Not very effective and easily dodged.

Rocks? Far more hazardous, especially given Akechi's typing. He could still try to dodge and watch the air, but it'd be far less predictable.

So, what to do...]

My attacking options aren't ideal. I'd try to use my speed and small stature to dodge the incoming attack and then retaliate with a Scary Face to slow its momentum.

Assuming I have teammates, I'd send Ren in to take advantage of the rock type's grass weakness. If flying solo, I would utilize a combination of evasiveness, coupled with Scary Face and Hone Claws until my Power Trip is suitably strong enough.

And, given the opportunity, I'd Roost to heal.
