Mario, Luigi and Fire Mario had navigated their way through the Mushroom kingdom, through Green Grass Gateway all the way to the next area, Lily Pad Lake, where a thunderstorm had started overhead about three days ago, and hasn't stopped since. It only seemed to be above the lake where the dark, thunderous clouds rumbled and crackled. The rain seemed endless and the storm was fierce, making the lake highly uninhabited as of late.

"It's almost as if that storm was started to keep people away from Lily Pad Lake," Luigi commented. Another thunder crackle sent a shocked Luigi into Mario's arms. Mario coaxed his brother to calm down, and that the lightening was too high up to hit them. Luigi got to his feet and pulled out the 3DS. It was fuzzy due to the lightening's interference with the signal, but Luigi could see that there were recuitable First Universe Ghosts above the thunder clouds. "I guess we need to get up there…" Mario huffed. "No, no way, count me out!" Fire Mario immediately spat. "I'm not getting within feet of all that water, no way in the First Universe."

Mario and Luigi exchange a confused look. "Are you afraid of water?" The both asked at the same time. Fire Mario nodded shamefully. "It's the only thing that can get rid of me, forever," He mumbled, ashamed his weakness was a little bit of H2O. "I know! What if we use the First Universe Ghosts we've collected up to this point to get us up there?" Mario asks. "That's not a half bad idea, let's do it!"

As planned, the ghosts helped the trio to their destination, a castle, green above the clouds, generating a thunderstorm below. Inside seemed to be an electrically run factory, full of lumas and more First Universe Ghosts. They all fled when the Bros. and Fire Mario approached. A screen with a silhouette came down, and the leader of this Stormy Castle-Factory spoke.

"So you arrive…" The screen's voice filter makes the speaker's voice indistinguishable. "You have come to take away the free people of this castle, just to use them for your own ploys, have you? You'll have to get past my trials to reach them, and me. There are five trials, each requiring a different skill. The fifth trial will involve one of you fighting me to determine what the fate of these ghosts, but that is the only hint I will give," the silhouette says, before the screen shuts off and retreats back to the ceiling.

The four upcoming trials were trials by fire, water, air and earth, having to navigate each room to the end without burning/drowning/falling/sinking in quicksand. Each puzzle was easily navigated and completed. There remained the final trial, trial by thunder. The door through to the next room had a strange, cryptic language written on it. "It's First Universer for 'Only those with a soul sparked by lightning may pass through here'" Fire Mario explained. "I kind of remember it as my brother's way of saying "Luigi's Only" back on the Thunder Starchaser." Luigi looked puzzled. "What's a Thunder Starchaser?" He asked. "It's my bro's self-built ship," Fire Mario elaborated.

"So, only Luigi can go through…" Mario mumbled absentmindedly. "I'm the one that has to take down the leader of this place…" Luigi groaned, not ready to take a boss on, on his own. "Don't worry about it, you'll do fine," Fire Mario commented. Luigi sucked in a deep breath, and entered the doorway, which was soon closed off by a green-electric grid. A hooded figure stood across from him, at the other side of the room. A crowd of First Universe ghosts tentatively watched their protector approach Luigi. "Shall we?" He cooed, it an almost too familiar tone, that sounded exactly like Luigi's own voice. Luigi simply nodded. The hooded figure approached to a battle's distance from Luigi, before the fight commenced.

The hooded figure gave a knowing look, before taking a mint green hand towards the hood, taking it off and commencing the first move, two electric swords from his own hands swinging violently at Luigi. He could barely dodge the other's attack, before attempting a hammer swing of his own. His attacker dodged swiftly and went in for another round of swordplay. Luigi could see now that the one standing in front of him was Fire Mario's brother, doing what his brother was earlier, protecting First Universe Ghosts. Luigi again swiftly dodged the other's attacks, and went for another hammer swing. The second Luigi avoided again, before landing a stinging, electric hit on Luigi, sending the younger Mario bro to the ground. This other Luigi, Star Luigi, stood over his counterpart's crippled form with a knowing smirk.

"I know what your problem is, current universer. You are highly predictable. You strive so to impress your brother, so you copy him. But, you're clumsy and a bit awkward doing this, am I right?" Star calmly asked Luigi. How could he know that, unless…

"Y-you did something like that, too?" Luigi asked, still on the ground. "It was a long time ago… But after I lost my brother to death, I decided I didn't need to copy him exactly anymore. I could act, think and fight like myself, not like Mario. You're still doing that, you're still predictable," Star elaborated coolly. "So, if you want to at least stand a chance in this fight, I suggest you act more like yourself and less like your brother."

Luigi got to his feet, and the battle continued. The younger Mario bro had to be less predictable. Every time he tried to attack Star with his hammer, he dodged to the left. So when Star tried this charade with the electroblades again, Luigi swung his hammer and made a large punch to his left, with his hand coated in electric sparks. Star got sent flying across the room. "Now that's more like it," the electrifying, starry captain thought to himself, before picking himself up and attacking again. Luigi prepared to read Star's counters and dodges, and act accordingly. It was the most comfortable feeling style of fighting he had ever had the chance to experience. No longer did he feel awkward and clumsy, but a new sense of balance and control washed over Luigi during this fight. It just felt right to swing his hammer more like a sword than a mallet, to dodge flexibly and use his lack of traction as an advantage. A more satisfied look crossed his opponents face as he fought this way, and things soon picked up into a more fair fight.

Eventually, Fire Mario tossed something to Luigi, with a "give it to him, and he should stop fighting" message written on it. The object was a chocolate bar. Star immediately stopped in place and locked his eyes on the candy. Luigi moved the chocolate bar around and Star's eyes never left it. He waved it and Star nodded. "Before I can give this to you, you have to let our bros through, and you have to forgive your brother," Luigi commanded. "I was planning to later, I overreacted and stuff, but then all these First Universe Ghosts came flocking to me, and I couldn't leave them unsupervised," Star explained. Luigi tossed Star the chocolate bar and Star got rid of the electric barrier keeping the Marios out. Fire Mario and Star Luigi gave their apologies and made up. The First Universe Ghosts were pleased that the heat between them and the current universers had died down, and soon made their way to Peach's castle.

"The least I can do now is help you three out," Star proposed. He joined the back of the line, just behind his brother.
