The Cactus Jack is a male anthropomorphic falcon from the 2017 Continuum.
Formerly a S.H.U.S.H. agent, desert-dwelling gadgeteer Cactus Jack ended up going rogue in the 1960's, luring his fellow agents Bentina Beakley and Scrooge McDuck into a house full of crazy deathtraps. This was the only mission at which Scrooge ever failed as a S.H.U.S.H. agent, and his memory of the events was erased until Cactus Jack resurfaced in 2019 with the same trapped house and an invisibility ray. Cathartically for Scrooge, however, he and Beakley were able to beat him fair and square that time around — and remember it!
