(this is during the anime episode five I think is when arfoire and the candidates are fighting)
3rd persons pov
As Rosario rode with the candidates,IF and Compa in himself he could feel something within something boiling he was looking down when the twins noticed they gave him a reassuring pat on the back
"Don't worry Rosario,we'll get big sis and the others back." The recently returned GPU (Guardian Patron Unit) he smiled and patted the two on their heads
"Alright, yeah let's do this!" He said as the vehicle stopped and everyone was out he noticed this and went after them "Hey! Wait up!" He ran after them and caught up panting as he saw the others looking up and there he saw something horrifying, all the CPUs caught in ... very questionable poses. He then ran toward the pyramid only to be stopped by an energy blast he saw where the shot was fired and saw arfoire above him he growled
"Well, well looks like the loyaly dog came back to his masters." Rosario growled louder "You growling only proves that you're nothing more than a dog." He stopped
"What are the CPUs trapped in that pyramid I mean?" Arfoire did nothing but start laughing
"They are caught in a anti share crystal pyramid." Rosario was pushed back and held by cords he struggled as the cords wrapped around his body contains his arms and legs he could only watch as the canidates fought arfoire. The rat came toward him with a smug look Rosario growled and shouted at the rat
"LET ME OUT OF HERE RAT SO I CAN BLAST YOU INTO OBLIVIAN!" The rat didn't falter though he did rubs his ears
"Don't think so those cords will keep you held long enough for the CPUs to be gone into oblivion." Rosario growled more he then saw electricity sparking from his hands he rembered that he had lighting dust in his gauntlets then he he felt his blood boiling and the electricity began surrounding him with a blueish/purple aura different than his regular red color he began to sceam in rage as the lighting exploded and he was freed, but his hands had been covered by armor like claws which actually were armor,but that what was only changed about him. He then kicked the rat
"GOODBYE RAT!" As he heard the rat screaming fade away and was breathing heavily as he walked toward arfoire as she was fighting the canidates she noticed him and fired several shots
"ROSARIO!" All the canidates and CPUs screamed Arfoire laughed at her victory
"Now that the fool is out of the way I can finally get rid of you brats." She was about to attack the canidates again until a lighting bolt hit her she winced "who hit me?" All of them turned or rather for the CPUs were still looking (to get a good visual of what he looks like just think of evil ryu except his top part of his gi is gone)Rosario now had an evil aura eminating from him,his eyes no longer the playful silver that the canidates and CPUs had come to know and love colored a blood and murderous red. His hair pointed up and dyed a crimson red with a blood colored headband that resembled a colored belt for students and finals his smile and seriousness had been replaced with a look of pure murderous intent and a hole where his heart was and glowed a black red
"IT'S TIME TO DIE ARFOIRE!" He then summoned two balls covered in flames and he proceeded to shoot a ball of dark energy that hit Arfoire and spent her down. He then changed back into his lighting covered body and had a lighting bolt in his hand he ran toward Arfoire. When he saw the pyramid and saw his worst fear... the CPUs he could feel their share energy drop he then activated his gauntlets which he based off his sister's weapon and punched Arfoire toward the pyramid she crashed into and Nepgear attacked Arfoire sending her through the pyramid prison a giant explosion occurred and Rosario transformed to normal, he dropped to his knees and screamed though this screamed again although it wasn't a scream of anger it was a scream of ... Sadness he had failed his job and his promise to all of them and worst of all ... to himself. He felt arms wrap around him he lifted his head and saw Nepgear hugging him along with the other candidates,even Uni but what made him start to cry was they all said
"Don't cry big brother." He then hugged who he could back he then felt weak and collapsed in the arms of the candidates.
