I've had my Orthworm moment.
I went after the Quaking Earth titan. Orthworm was on my team essentially to leech EXP, being ~10 levels below the rest of my Pokémon at the time. Everyone else fainted, so in went the worm so I could toss a revive on one of my stronger 'mons, and... Wait, the titan did how little damage to this goofy fucker?
Orthworm basically single-handledly bodied that titan for me. He made it to the Elite Four, lol. Long live the Orthworm!
