Suggested by Sonic Squirtle and Lucario are both pretty powerful Pokemon. In their base modes there is no question that Lucario would stomp the water type, but when you throw Blastoise in then things get interesting. That being said, Lucario has better firepower as well as superior hand to hand combat skills. When you mix those two elements in then there’s just no way that Squirtle can claim the advantage. He’s simply outmatched by Lucario’s pure ability. Lucario wins.
