Pikachu can learn Brick Break from the TM. Just saying... :P
Still, Pikachu don't do well with physical attack or defense, Onyx is what Rock/Ground? Both of which are more known for having higher defense and attack, just doesn't go well for it. Sure Pikachu has the speed advantage, but Onyx not only has attack and defense advantage, but also a type advantage. Not to mention STAB for ground type attacks, which Pikachu is weak to.
True. Well, I wouldn't do that anyway, but I usually don't change my team for one fight either. So if Pikachu were in my usual team, it would accompany me into this fight as well, even if I'd have to rely on the other five Pokémon to win without Pikachu's help.
