Suggested by Destroyer The Road Runner has a solid amount of speed. Howard can’t hope to land a single shot with his bullets on a foe like this. Everything he tries will get absolutely blasted back in his face which doesn’t bode well for his chances of survival here. While the Road Runner may be lacking in offensive moves, you don’t need much when you have this level of speed. Even a normal attack will get amplified to a high level if delivered with enough force. Road Runner wins.

Again, another battle that could go in Howard’s favor. Considering how many roadrunners are killed in the southwest yearly, give Howard a gun, and he could kill the roadrunner.
That’s true, but this Road Runner isn’t quite like the rest. He’s taken on quite a lot in his day but for sure if Howard lands a shot then it’s all over
