A fully-evolved Cycad's description appears to list it correctly as a plant, but the game seems to treat it like a monster; that is, a Monster Hunter can gain base damage from a Cycad and mark it for destruction, yet it can be saved from destruction by a Paramedic.
Just had an odd moment where a Mad Scientist turned one of my Civilians into a Tax Accountant who marked himself for destruction on the next deployment.
A Tax Accountant drafted normally later that same wave made it through his usual 5 deployments before exploding into a cloud of W-2s.
I can't help it: I absolutely adore the Hustle Goblin. I imagine him working out between battles with a mantra in mind. "When the team does better, I do better; when I do better, the team does better!"
Such a plucky little dude, I'll take him any time he's offered.
