Note: this is his lore taken straight from the funkipedia mods wiki

Despite the common misconception, he isn’t a suck-up or a mindless follower of Tom. He’s simply a highly enthusiastic and disciplined member of the army. It’s what earned him his position as the army’s leader. He doesn’t inflict torture out of pleasure (at least not when he isn’t under Tom’s control), he’s just following orders.

When free from Tom’s control, he’s not as cruel: grounded, laid back and even sympathetic at times. But fear drives most of his obedience. He knows what Tom can do, and that fear often makes him look like he’s kissing up to Tom, when in reality, he’s just saving his own ass.

Deep down, he believes Muffin’s rebellious nature might be their only hope. That Muffin’s defiance could eventually break the nightmare Tom has trapped them in. He’s aware that if Muffin dies, Tom’s show would suffer, maybe even collapse entirely. He wants to help Muffin, but Tom sees everything.

When Tom takes control, however, he becomes unrecognizable. Completely deranged. All of his suppressed anger and fear twist. Under Tom’s influence, he despises Muffin with a BURNING passion. That hatred isn’t really his own. It’s Tom’s anger projected into his mind, a way for Tom to make sure no one else can escape the obsession with keeping Muffin alive.

Controlled Rodriguez takes any opportunity to torment or fuck with Muffin, always with that toothy smile laid across his face
