Crit-Sandvich

The Crit-Sandvich is a type of Sandvich that may have debuted in the Team Fortress series, but in the series, it debuted in the sixth episode, The Quest for the Ultimate Sandvich. It is known for being a shining blue-chrome color, and holding mighty power in both appearance (whoever eats it becomes blue-chrome as well) and combat.

Known eater(s)
The only known eater of the mighty Crit-Sandvich is Blue Heavy.

Known victim(s)
There are only 2 known victims of the sandvich's power. Red Heavy and Spy  were attacked under its power, both with the method of the three-hitting punch, only Spy had a worse income, as he was punched into an abyss. The reason Blue Heavy himself is a victim alongside an eater is that he suffered the explosion because the same spy who died had rigged the Crit-Sandvich with C4 that was likely rigged to explode when eaten.

Known owner(s)
The only known owner of the Crit-Sandvich is the Spy, the one who placed the mighty sandvich in the box in the first place. Scout also had the Crit-Sandvich until his front bike wheel wonked out and he fell into a pond, releasing the Crit-Sandvich from his grasp. Soldier also kept the sandvich in a cage for a long time.
