The young kid slowly opens his eyes from staying out cold as he was in stitches after getting beaten up by Riser earlier in open space when he tried to save Rias from him. As he slowly sits up, he found himself in a bedroom he wasn't familiar with.
He thinks to himself. "W-Where am I? Did I have some sort of a nightmare or some sort?"
Rosalina walks into the bedroom to check on the kid to see if he's ok.
"Ah. You're awake now." She walks over to the bed as she sits down and looks at him
The young boy looks up at Rosalina and rubs his eyes a little "W-Who are you Miss?"
Rosalina scoots a little closer to the boy so she can look at him in a better angle "My name is Rosalina. Princess of the galaxies, and mother of the Lumas. My Lumas found you floating alone in space powerless and injured, so they decided to bring you to my comet observatory where you can recover soon"
"I-Injured?" Then he remembered what Rosalina meant as he looked down feeling sad as he shed a tear also feeling very ashamed in himself "I-It's because I was trying to save Rias from Riser...And right now, I realize that I'm not strong and powerful enough to face against Riser in order to save Rias...I-It's all my fault" He continued to break into tears just by thinking about it
Rosalina gets closer to him and hugs the kid comforting him "There there. It's not your fault. I know that because you tried, but that doesn't mean that you get to stop now...Once you're fully recovered, you'll be able to set off on a journey and stop Riser once and for all!"
The young cute boy wipes the tears off of his face and looks up at Rosalina "R-Really Princess Rosalina? T-Thank you"
Rosalina smiles at the kid "Your welcome little one...You must bed tired. I'll give you some quiet time so you can rest"
The young kid did feel tired as he yawned a little "Y-Yeah. You're right Rosalina"
Rosalina smiles softly as she released the kid from the hug and have him lay down on the bed "Sleep well young hero, and may the stars shine over you" She turns the light off in the bedroom, and leave the boy alone so he could sleep
"G-Goodnight Rosalina" The young kid slowly shuts his eyes and starts to fall asleep cuddling his head on the pillow
-later-
The kid slowly opens his eyes after hearing some loud commotion going on outside on Rosalina's comet observatory. He slowly sits up as he was now fully healed. He stretches a little as his body parts were moving very well before. He thinks to himself "What's that sound?" He gets up out of bed, puts his shoes on, walks out of the bedroom, and sees a huge golden chain chomp running around the comet observatory "WHAT THE HECK?!"
The chain chomp was out of control. It was zooming through the observatory without a leash on its back.
Mario and Luigi were zooming through the observatory trying to outrun the chain chomp no matter how many times they tried to stop it from hitting them. Not only that, they also had the baby bros. with them as they tried their best to keep them safe from the golden chain chomp.
The kid then noticed a hammer laying in front of him as he thought he should use it against the Golden chain chomp
"Hm? How did this end up here?" He picks it up as it was surprisingly light enough for the kid to carry in his own hands "Whatever this hammer is doing here, I think it might help me to defeat that weird looking dog-like thing!" He dashes over to the golden chain chomp as he sets the hammer getting ready to hit the golden chain chomp at the right moment "FOOOOOORRRRRREEE!!!!!" He hits the chain chomp hard as it flew across the observatory and exploded into a million pieces. What came out from the golden chain chomp, was a power star. "I-Is that?"
Mario walks over to the kid and nods as he pats him on the shoulder "Yep. That's one of the power stars we've been looking for ever since Riser took a lot of the power stars from Rosalina's observatory stealing the energy and light."
The kid turns around to look up at Mario as he was shocked after hearing what he said about Riser "You know about what's going on too?!"
Luigi then walks over to the kid with the Baby bros. on his back
"Yeah. It all happened at the same time without warning..."
The kid looks over to Luigi with the babies that's on the Italian Plummer's back "Oh...Wait a minute. Are you two, the Mario Brothers?"
Mario looks back over to the kid and smiles "Yes we are! We're the Mario brothers!"
Luigi smiles and nods at the kid "Yep! And we heard that you're Ben on a mission to save a crimson haired girl named Rias Gremory from Riser!"
The kid's eyes sparkled with amazement "It's nice to meet you two and the baby brothers, too!"
Baby Mario and Baby Luigi hopped off of Luigi's back and smiles cheerfully at the kid
The kid thinks to himself "Those babies are just too pure for this world! They're so cute!!"
Mario then thought of something "Hey. Since you're starting a whole new adventure on stopping Riser from taking over the entire universe and saving Rias from him, why don't you join us so we can all stop him as a team!"
The kid was surprised after he heard what Mario said and immediately nods at the offer "Of course I'll join you and the others Mario! Let's all stop Riser before we're too late!"
Luigi smiles filled with determination and excited feeling ready to set off on a new adventure with his brother and the baby brothers "Alright!"
Rosalina heads over to the brothers, babies, and the young hero with urgent news "Bad news. Bowser is now under Riser's control"
The five heroes were shocked after they heard what Rosalina said to them
The kid steps forward as he looked up at Rosalina feeling almost completely speechless "B-But how?"
Rosalina sighs "I think Riser got the better of the Koopa King so he was able to brain wash him and be on Riser's side. Not only that, he has Princess Peach with him..."
The kid was now angry after he heard what Rosalina explained about what happened to Bowser "That, does it! We need to get Bowser back to his senses quick before he does something terrible to the mushroom kingdom!!"
Mario looks over to the kid and nods agreeing with him "Right! Let's go!"
Luigi nods with determination as he places the baby brothers down because he was worried for them to get hurt since he thinks the enemies that he, Mario, and Ben will face against will be more tougher than the enemies he fought against in the past "Alright!!"
Rosalina then stops the brothers and the kid super fast "Wait!...Not only the mushroom kingdom, and the other places in the world you Italian brothers go to, but to other worlds as well..."
The kid was shocked after he heard what Rosalina said as he was now filled with fury "That's all I can stand, that I can't stand no more!"
Mario and Luigi were feeling the same way as the kid was and starts running to the launch star to make it over to Bowser's castle quick "Come on Ben! Let's go!"
The kid nods as he follows them from behind "Alright Mario and Luigi! Let's go!!"
The Mario brothers and the kid jumps into the star launch as Mario spins, and launches him, his brother Luigi, and the young hero are launched to Bowser's castle fast.
The kid looks ahead and sees Bowser's castle in the distance "There it is! Hang on Bowser! We're coming for you and to save Princess Peach!!" He then lands with the Mario brothers near the castle as he was shocked to he how big it was in front of him "Holy cow!! I wasn't expecting to see Bowser's castle THAT huge!!"
The Mario brothers looks over at the castle the kid was talking about as they were surprised at the size of it as well
Mario walks over to the kid with Luigi still shocked at the size of the Koopa king's castle "Mama Mia. I think Riser and Bowser upgraded the castle so it would be more difficult for us to pass through and make it up to him."
Luigi looks at the castle with Mario and Ben as he walked over to them "Just by looking at how huge the castle is right now, I guess things aren't going to be much easier now that Riser is controlling everything in the universe now..."
