When the bombs detonated inside the Sari Club in 2002, Bali was rocked by the wave of terrorism which threatened to engulf the world. Yohana found herself thrust into the disaster and tried as best she could to evacuate the injured. When she was approached by a large man in army fatigues she thought he might offer assistance, but it was Gunung of the Marauding Tide, and he was there to contribute to the suffering.

Yohana barely evaded his oversized fists and barrelled away from his assault. When she pulled herself off the ground she was surrounded by Bayu and Matari. Sirens blared in the distance.

"You might as well give up, girl," Bayu said with obvious disdain. "Your kind need to lay the road to our eventual salvation."

Yohana balled her fists.

"You'll have to do worse than throw words at me," she called back, and her body was suddenly surrounded with flames. Marauding Tide were obviously startled and she pressed her advantage, flying directly through Bayu, landing with all her strength against the other woman. They landed with a crunch and Yohana stood up ready to face the others.

Matari swung with his fire fists, but he missed, enabling Yohana to grab him under the arms and lift into the sky. He screamed out in surprise just as she dumped him into the ocean. The wind began to whip around her and she realised Bayu had returned, but instead of a battle, Marauding Tide vanished leaving Bali to burn slowly.

Yohana looked to the horizon but saw no sign of the terrorists, so she had no other course of action apart from returning to the disaster and helping as much as she could. The following day she was contacted by Bidadari, an organisation of women who wanted to represent the antithesis of Marauding Tide. Bidadari had approached Yohana before, but she wasn't interested. The second message arrived after the bombings and simply read: "Ready now?"

She knew it was time. Terrorism had been allowed to fester for too long. It was time for the Bidadari to reclaim the hearts of hopes of the Indonesian people.

Yohana is young and spirited, but can come across as impulsive and not entirely reliable. She is outgoing and optimistic about the world, and believes that the Bidadari are making a difference. She works part time as a waitress, but of the three Angels, she is the one who is more concerned with her heroic identity. If she could, Yohana would live as Matahari Merah full time.

“You really don't want to mess with us. We're on the side of the Angels.”

Matahari Merah means "red sun" in Bahasa, and she possesses the power of the sun, enabling her to create fire and heat for a variety of effects. She is also gifted with uberhuman strength and durability, as well as the ability to fly. Of the three Bidadari, Matahari Merah is the most powerful in terms of raw energy, and is often used as the spearhead of any direct attack.

Yohana is young and friendly, always with a friendly welcoming smile and bright white teeth. As Matahari Merah, she wears a red bodysuit with an exposed shoulder held together on the strap with a star. She also wears white boots, belt and gloves, and wears a red visor to protect her identity. When she flies, Matahari Merah leaves behind a trail of fire which dissipates after a minute.
