Underrated Fun Creatures To Play?

Just like the title says! I’m looking for some of the most underrated creatures that are also the most fun to play. For example, I think Xenolif is super fun to play (my main!); it has great abilities (jump, wall climb, radiation, etc) and yet I never see anyone use it. What’s your favorite creature with a fun playstyle that you never see anyone use? Not based on strength, but enjoyability!
