Sorry for the double post, but I playes on PS for a bit and remembered 3 sets that I run that shouldn't exist, at least partly. First off is Ursaring:
Ursaring learns Gunk shot and Seed bomb! WTF!? (I run gunk shot because it's got a large BP, and if I switch into a threat that could set up I use it instead of protect, I don't run seed bomb) and somethinf else strange with them is that they are physical attacks! Anyway, onto my second pokemon, octillery!
Octillery learns:
1) Flamethrower
2) Charge beam
3) Energy ball (I can kind of picture it, but it doesn't suit him.)
And then number 4, ice beam, I'm letting him off for because lots of water types learn it somehow. But flamethrower is the biggest mystery, I used it in a battle just now and my opponent went mad! Energy ball you can kihd of see him using, but it doesn't... work and charge beam, while great competitively, since after 2 boosts little can stop 2HKOs, doesn't make sense coming out of Octillery's.. uh ... snout. Lastly is Girafarig (don't knock him 'til you've tried him) and though I know that these attacks probably come out of his chain chomp on the end of his tail, it's not big enough to produce energy ball, really. Anyway, Girafarig:
Energy ball
Signal beam
Thunderbolt
Now, thunderbolt seems to be a thing with psychic types, hello reuniclus and starmie for 2, but it seems to make the least sense when coming out of a giraffe! Well, actually, the star-fish would die if a thunderbolt struck it so that might make less sense. None the less, Giraffes are tall and so are more viable to get hit by thunderbolts! Then we have signal beam (Girafarig has a fairly limited special movepool, which is a shame because it's 3 psychic attacks are special and it's best normal STAB is special and you can't really run a mixed set on him), I have signal beam for coverage, namely dark types and Musharna, but I can't see green light coming out of it's tail or mouth (the one on his head that isn't attached to a tail but his neck), so it's just weird... And then we have energy ball, well, this makes the most sense because you can see it coming out of his tail kind of so... yeah.
