Its one thing to scale a Tiger to a Wolf, since Tiger's are a superior category. On the other hand there's not a lot of reason to scale every wolf to other wolf just based on their classifications. As an example Dragon level threats range from people like
Bakuza is a Dragon level threat at >9.36 Megatons on the other hand
Boros is a Dragon level threat with >23.809 Petaton physical attacks and 183 Petaton super-attack. Despite being of the same ranking, one's vastly above the other.
Same here with Tongue Stretcher and Piggy Bancon, though not as extreme.
