Uroboros Aheri is a unique Infected card in the Resident Evil DBG. It is the "boss" of the base set, and its defeat marks the end of the game no matter what. Aheri has the highest amount of Health and Damage in the entire game alongside Albert Wesker (the "boss" of the expansion set Alliance); which is 90 Health and 70 Damage. This gives it the power to kill several characters in one strike (such as Rebecca, HUNK, Steve, Ada (not counting her third card, and Claire). Aheri also has an effect; if it is not defeated, it must be shuffled back into the Mansion Deck. Ironically enough, the Satellite Laser Device (the weapon that kills it in RE5) appears in Alliance with the same effect after it is used.
