Both, with Ultraboy's help

Ultraboy saw Ultimamom and rolled, he wasn't strong enough to stop her, but...a though occured. He rolled flexibly bringing his chained hands around in front of him and began to move. Despite the chains on his ankles, the sound of his mother battling his beautiful counterpart let him get behind her.

He locked the chain around her throat and wrapped the chain around his wrist, using it as a lock, despite the supervillain's greater strength, she couldn't pull free without breaking his invulnerable arm. He lifted one leg as far as it could go, shackled as it was and planted a knee in her back. She flexed against him, pulling hard, but only pulled herself more tightly against the chains, **** herself further.

His mother's counterpart pulled desperately at the chains, but couldn't break them, as she couldn't get any leverage, nor could she pull free. She stood up and managed to slam Ultraboy against the wall several times before she finally collapsed to the ground, ****, with Ultraboy atop her.

He rose and staggered back towards his mother to see how she was doing.

Ultimagirl was **** on the ground.

"There you are! Honestly, what would you do without me?" Ultramom asked as she produced the key from the van. She'd missed the entire fight with Ultimamom...
