Think I've got it - it's Magby. Black part is its throat collar thing that I don't know why I remember it has that. I think if it gets to this many guesses without a right answer then we just move onto the next question though honestly.
That looks like Magneton to me. Also - I think that at worst, we should give everyone one guess, then you can confirm or deny everyone's guess and maaaaybe give a hint, and then give them one more chances to guess.
