Who Is the Weakest Strongest Pokémon?

It's time to revisit a topic from way back, and consider a ridiculous premise that very few people would ever bother coming up with. But out of the Pokémon we might consider the strongest of their region, which one could we say is the weakest of those Pokémon? (If you have different way of categorizing the data, or different metrics you would prefer to focus on please tell me about it in the comments!) https://www.deviantart.com/ishmam/art...
