I think my Remoraid's nickname is perfect for it. I call it Aaroniero because to me, Remoraid represents Aaroniero's Kaien disguise, while Octillery is the perfect embodiment of his Resurreccion. I also named my Kingler Barragan. Crown-like horns, oversized weapon, and "King" in the name - I mean, do the math!
Of course, not everyone is as much of a Bleachtard as I am.
Please stop complaining about Pikachu losing to "weak" Pokemon at the start of each new region. Its power is drained at the start of each new region, and anyway, it's equally bad storytelling for Pikachu to plow through all of its opponents.
