Mack is a strong, steadfast, and tactical character with a good head on his shoulders.
Henry Simmons’ Mack joined the show in Season 2 and is one of the earliest additions who stuck around for the remainder of Agents of S.H.I.E.L.D.’s run.
Since these last two additions were equally great, they both deserve the #1 spot!
However, he’s a big softie on the inside and cares very deeply about everyone and doing what’s right.
