Definitions for "Hydralisk"
a unit in Blizzard's real-time strategy (RTS) game Starcraft, deriving its name from its serpentine body
Hydralisks are a staple unit in the Zerg army and are reknowned as the Hive's bread-and-butter unit. For only 75 minerals and 25 gas, they are extremely effective for their cost and can overpower the more expensive Terran Goliath. Dealing explosive damage, they are not as effective against small units but can deal with them none the less.
a tempting companion, but since that option isn't directly available, I'm inclined to choose mutalisk as well
