And that headcanon all started because I wrote a human Galvatron as having a shitty diet in “Space Vagabonds” and doing shit like eating a raw onion like an apple because he’s a gross sad asshat who got very tired with life.

Headcanon

Unicronians are total garbage guts.

They can eat lots of things normal Cybertronians can’t.

Some tainted, damn-near poisonous Energon? Yeah Galvatron
ate it, no big deal.

Some unidentified glowing substance produced from some
experiment? Cyclonus just chugged the whole barrel for a quick drink.

Scourge and Sweeps being able to track down, kill and eat
organic creatures, even scavenge meat off rotting corpses.

They’ll just fucking eat it all.
