What other pokemon based off the seven deadly sins could we get?
Give them abilties that hinder them (to show that sins only hold you back)
Pride:Pokemon is unable to attack pokemon of a lower base stat total (Too prideful to attack something it deems weaker)
Gluttony: Pokemon's held item is used for 1 turn before being dropped (Quickly used up its resources)
Greed: Pokemon cannot switch out if it makes another pokemon faint (Greedy for the kill)
Envy: Pokemon cannot faint pokemon of a higher BST. (No matter what you do to a person you're jealous of, they will always be better than you)
Wrath: Pokemon is always confused after attacking (Blind anger does more harm than good)
Lust: Pokemon cannot attack pokemon of the opposite gender (Too infatuated)

Of course they'd have different names like how sloth is truant.
