>>31491421Make carnivine's regular ability strong jaw instead of levitate, and give it a hidden ability called flytrap: think of storm drain, but for bug types. It can work as an attacker with strong jaw, or as a rage powder/leech seed/infestation/toxic support in doubles with flytrap, helping mons that have an important weakness to u-turn, like malamar or exeggutor, to set up. This last set is situational tho, as carnivine still has other important weaknesses and is slow.
Give carnivine a grass type biting move, and a few fang moves (poison fang, thunder fang maybe). Also give it knock of and poison jab.
Finally, give carnivine a crossgen evo, allowing carnivine to hold eviolite and improve its shit bulk.
>>31491469 I would guess a mix of hydra/swamp monster and multiple heads could work.
