Agents Of SHIELD: 10 Best Villains
7. Lash
Lash showed up at the top of the third season in vicious fashion, hunting and killing his fellow Inhumans without remorse. For the first stretch of episodes, little else was known about him, with the threat of his appearance lurking around each and every corner.
And then came the bombshell that Andrew Garner, Melinda May's ex-husband, who fans had come to know as a compassionate ally of the team, had been Lash all along, having accidentally been exposed to one of Jiaying's Terrigen Crystals. The event left him coping with a Bruce Banner/Hulk-esque situation, constantly fighting a losing battle for control against the far more powerful Lash.
In the end, Lash won the war, but the "monster" went on to battle Hive and free Daisy from the mind control, only to be caught off guard and killed unexpectedly by Hellfire, bringing an appropriately tragic end to one of the show's most tragic characters.
