Hahaha oh my god. Hang on. Okay, so this is Mega Eelektross' signature ability. You know how I've been saying abilities like Innards Out and Parental Bond are basically asking for fakemon to be made for the express purpose of jailbreaking said abilities from the one (1) mon they were custom made for? WELL....
Faecilian and Sorcilian are two of my only fakemon that I did decide the abilities of (Magic Guard, Water Absorb, HA Magic Bounce) and I still think that's solid. Especially since, as Fairy/Ground types, Water Absorb removes their weakness to Water.
Liviscous and the rest of its kin have signature abilities for their disease theme (Nasal Spray- Water moves have a 20% chance to poison), but they could always be given hidden abilities like the Loyal Three do. A Poison/Water type with Ground immunity would be diabolical.
Same goes for Hagloop, another poison type. Granted, there's no world in which this thing is floating off the ground.
Eelabyss is the only true eel rather than a caecilian or hagfish, but the Eelektross line are lampreys so this whole thing is subjective to start with. It's pure water so it doesn't really benefit, but giving this thing a type immunity, immunity to most hazards, and Beast Boost for absolutely no fucking reason would be funny.
Basically, the winds are calling me to create a Poison type eel to give this ability to
This, folks, is called providence.
