Over the past handful of major events, I wanted to see which of the "alpha monsters" were better than others. These are what I call the hardest monster (final monster) to obtain in mazes and progressive islands. If you are a Gem Whale, you probably have all of these monsters anyway - but which do you prefer using and why?
Hackster (aoe possess, 2 single possess moves, makes enemies lose turn, immune to magnetizing)
Rabies (aoe burn, gains TRIPLE damage, makes enemies weak to fire, great power, immune to stun)
Kiridar (destroys shields, 2 single stun moves, makes enemies weak to nature, immune to possession)
Captain Copperbeard (aoe stun, aoe burn, activates cooldowns, great power, Mountain trait)
Baba Yaga (aoe possess, 2 single possess moves, great speed, immune to possession)
