The blue Hippo. Both cards cost 2 and can be removed from the game disable an ice, but Hippo's destruction effect is more permanent and powerful. Capybara somewhat makes up for this with a trigger that is harder for the corp to play around and a lower influence cost (but factions importing Cap will also need some bypass effects).

I wonder what green river mammal will come in the next cycle? Perhaps a platypus?

Capybara (🦫🕶️) upgrades a bypass into a derez.

Flavor: Capybaras are known to be chill; so chill, that they chill “semi-chill”, aka. bypassed, ice until it's “super-chill”, aka. derezzed. (What @m.p calls the Chill Tier.)

Also, they're the largest land rodent, they love bathing in water (hence, the artwork), and they live all across Brazil (hence, being in this cycle).
