Maybe Heat and pop. The plastic is stuck to plastic and if you put it in Boiling water for a good saaaayyy 10 seconds??? This will make the plastic expand and more rubbery. take it outta the water and take the helmet off. Then let the plastic harden again. Like Mr. Therapist said I dont know how it will effect minimates as opposed to regular figures.
Hope it helps!
