If it's an issue, I'd go for the opposite. It's final form has it suddenly super healthy. Maybe it's first two forms could have poor stats, and some ability that causes it to take damage each tern, but if you stick with it, it's final form is health, has a major stat boost, and has an ability that makes it immune to poison or whatever.
