Would this actually work? [Spoiler]

Do you think this could actually work against bulletproof or Invincible (Mark). After all it was established that Marks insides are not nearly as invulnerable as his outside when Robot destroyed Mohawk Mark from the inside.

The timing would probably be almost impossible to pull off, even for some as skilled as Best Tiger (or do you think otherwise), but in the case that he succeeded, do you think this could kill either Bulletproof or Mark?

Idk about Bulletproof but all this will do is piss Mark off. For whatever reason damaging a Viltrumite brain is not permanent for them, the heart is the only way to stop their regeneration from working
