The Cave of Eternity echoed with the crackle of lightning.
Now that the ritual was complete and he explain important things,
It's time for them to train their power.
"Alright," Arin said, spinning the staff once.
"Time to learn what your powers can do."
Mary, MJ, Rosa, and Darla stood in their Shazam forms, glowing with divine energy.
Gwen watched from the side with her hood up, acting like the "experienced hero supervisor."
Darla bounced on her feet.
"TRAINING TIME!!!"
MJ cracked her knuckles.
"Oh yeah, let's go. I wanna punch something."
Mary smiled nervously.
"I hope I don't accidentally blow anything up…"
Rosa held her hands together.
"I… I'll try my best."
Arin laughed softly.
"You'll all do great. Come."
Arin pointed to a massive boulder in the corner of the cave, bigger than a small truck.
"Mary, try lifting that."
Mary blinked.
"That?! But—"
"Trust your power."
She hesitated, then placed both hands beneath the giant rock—
There was a heartbeat of silence.
And then—
She lifted it over her head like it weighed nothing.
MJ's jaw dropped.
"No way—"
Gwen shouted, "MARY WHAT?!"
Mary stared in shock at her own hands.
"I—I can't even feel the weight!"
Arin smiled proudly.
"That's the Strength of Hercules. You're not just strong… you're unstoppable."
Arin turned to MJ next.
"MJ. Try running."
She raised an eyebrow.
"That's it? Just run?"
Arin smirked.
"You'll understand in a moment."
MJ shrugged and began jogging.
The moment her foot touched the ground—
BOOOOM!!!
A sonic boom echoed as she vanished into a blur.
She zipped around the cave—
three laps in a single second—
and reappeared in front of Arin, hair blown back.
"WHAT THE—
WHAT JUST—
HOLY—"
She grabbed Arin's arm.
"DO YOU HAVE ANY IDEA HOW FAST THAT WAS?!"
Arin grinned.
"Mercury's speed. Faster than lightning."
MJ's eyes sparkled.
"Oh, I am going to have fun with this."
Rosa stood quietly, nervous.
Arin approached her gently.
"Rosa… your gift is different."
He placed two fingers on her forehead.
"Relax. Let it come naturally."
Her eyes glowed faint gold…
…then widened suddenly.
"Oh—! I… I can feel things.
I can read the magic of the cave.
I can understand languages written here…"
Mary gasped.
"So she got… magic intellect?"
Arin nodded.
"Wisdom. Strategy. Insight.
You will guide us when things get difficult."
Rosa smiled softly—proud, calm, elegant in her new power.
Darla crackled with electricity, sparks dancing off her fingers.
Arin crouched to her heightand said:
"Focus your feelings.
Think of your joy."
Darla giggled and raised her hands—
KRAKOOM!!
Lightning shot from her palms, blasting a stone pillar into dust.
MJ jumped back.
"OKAY. Never making Darla angry."
ZAAAP—
Darla clapped happily.
"I CAN DO THUNDER!!!"
Gwen laughed.
"Darla is basically a portable power plant."
Arin patted her head.
"Great job."
---
After hours of training—lifting mountains, firing lightning, high-speed running—
Arin look at them again.
Mary looked excited.
MJ looked hyped.
Rosa looked peaceful.
Darla looked like she wanted MORE.
"Are you girls even tired?" Arin asked, exhausted just watching them.
Mary lifted another boulder.
"Nope!"
MJ grinned.
"Barely warmed up."
Rosa smiled serenely.
"I feel more refreshed than before."
Darla jumped.
"TRAIN MORE!!"
Arin sighed.
"Right. Champions really don't get tired…"
---
As training calmed down, Mary approached Arin shyly.
"Um… Arin?
How do we… um… turn back? Into human form?"
MJ perked up.
"Oh yeah, good question!"
Rosa nodded.
"I don't want to walk into school tomorrow looking like a goddess…"
Darla added:
"I don't wanna scare people with lightning hair!"
Arin chuckled.
"Simple.
To transform into your human forms—or back into your Champion forms—"
He lifted his hand dramatically.
"You just say…"
The girls leaned forward.
Arin spoke with a smile:
"Shazam."
Instantly—
KRAAASH—FLASH!!
Arin reverted to human form.
Mary, MJ, Rosa, and Darla gasped.
Mary whispered:
"So just… say the word?"
Arin nodded.
"Go ahead."
The four looked at each other—
Then loudly:
"SHAZAM!"
---
Four Flashes of Light
BOOOOM!!
In a burst of golden lightning, all four reverted—
Mary to her gentle beauty,
MJ to her fiery confidence,
Rosa to her warm elegance,
and Darla to her small child form again, stumbling and blinking.
She looked at her little hands.
"My fingers shrank…"
Everyone laughed.
Even Arin couldn't help smiling at his chaotic, magical family.
