As playable characters weren't integrated until after release, the announcers don't have unique lines referring to characters other than Batman. If not playing as Batman, the lines that directly reference Batman are simply not used.
"There's just one left Batman, stop playing around and finish him. I've got plenty more."
"You were supposed to be the best. You're not worthy of the training I passed on to you. If you were, he'd be no match for you!"
"You were trained for this! Focus!"
"You know how to beat him, Do it!"
"Stay focused! He wants you to panic!"
"Take him down, no excuses!"
"I teach you every move he's got and you stil don't see him coming. Pathetic."
"You might think you're safe, but you're not. The Bat's still out there. Don't let your guard down."
"Keep all bases covered! He's sneaking around in there."
"Show me courage, not fear!"
"Report In, all of you."
"You've got men down out there, check last known locations."
If you take out other present forces while the above is happening;
"We've got a radio silence, someone's down. Sweep the room!"
"Find them, now!"
"Deploy Sentry guns! Pin him down, now!"
"I want a sentry gun in that location. Keep him pinned down!"

Explosive Gel Takedowns;
"Be careful of the weak walls and fragile structures, He can rig them to blow."
"You still fight like a coward. Careful of weak walls fragile structures. He can rig them to blow."
"Okay, so you have learned some new tricks. He's mimicking my voice, switch channels."
"All these years, and you still fight like a coward. Two man teams, sweep the room!"
"Cheap shot! I'll give you that one for free. Pair up, watch your backs!"
"Beautiful, Batman. He never saw you coming. But the others will. No one goes alone, Work in pairs and find him!"
"Hiding in the floor won't help. He's under the grates."
"Using the floor gates? Good move. Here's mine. Batman's under the floor. Destroy those grates and flush him out!"
"Keep an eye on those ledges. He could be hanging there, just waiting for you to walk by."
"You're a creature of habit, Batman. Let's see if you can break it. He's picking you off from the vantage point. Get a mine on there now!"
"Mine those vantage points!"
As with male characters, the announcers don't refer to specific characters during challenge maps. However, female characters are referred with correct gender pronouns. The lines are otherwise the same as with male characters.
"Deploy Sentry guns! Pin her down, now!"
"I want a sentry gun in that location. Keep her pinned down!"
"She's creeping up when your back's turned. All of you, watch your damn six!"
Explosive gel takedowns
"Watch the walls. She can destroy them."
