I saw this. I remember Grodd from the Flash series. The movie Grodd is too strong compared to this one in Injustice 2. I remember Grodd grabbing Flash with telekinesis from far away (full screen distance) and pulling him towards him, and then punch him to the bridge.
BTW, I did read previous comments about comparing him to Kenshi and Ermac there. Let me tell you some tips.
Kenshi IS the telekinetic guy, which should be clearly compared to Grodd. Within the telekinetic powers there's, also, the mind controlling and reading.
Ermac is a psychokinetic guy, who, as the word states, controls and moves the souls.
Therefore, since he's a way stronger brute he should be a stronger brute than who they now introduced.
