Juggernaut

One of the interesting things Marvel Rivals does that deviates from Overwatch 2 is including destructible environments. This means if an enemy is using a building or other structure for cover, you can do enough damage to them that they crumble to the ground. Pretty much any hero can reasonably knock a wall out, but what if there was a character whose specific role was to punch holes in a wall? Enter Juggernaut, the mutant with incredible strength whose most iconic live-action moment involved chasing Shadowcat through walls in X-Men: The Last Stand
Juggernaut is an easy pick for a Vanguard (tank) character, as he is incredibly powerful, could disrupt teams easily, and would have a lot of survivability. Give him a charge ability that breaks through the environment with reckless abandon and he’s set.
