"All that matters to me in this world is... ...To get back Sis. I have no intention in participating in your argument of good versus evil."
Last Vigilante 
BlazBlue: Calamity Trigger (playable)
Carl Clover (カルル＝クローバー) is the current wielder of the Nox Nyctores – Deus Machina: Nirvana, an unfortunate victim of circumstance, and an exceptionally talented young man. Carl is a top rate vigilante who masterfully snares his targets with Nirvana to help bring them to justice. His sister, Ada Clover, is the subject of his admiration, but her transformation into the Nox has forced him to seek ways to save her. For this reason, Carl seeks out the Azure Grimoire, as it might be one of the only viable methods towards saving her.
He is one of the original playable twelve characters who debuted in BlazBlue: Calamity Trigger.
Carl is a young, pale boy in his early teens with blue eyes and nose-length blonde hair. He wears thickly rimmed glasses and a large purple top hat on his head. His usual attire consists of a purple cape tied around a long-sleeved white shirt with an ‘X’ shaped fixture, from which a large bell dangles from. Deep purple shorts with white cuffs are part of his usual attire, as are purple military styled boots with a screw fixture attached to the cap of the boot. Carl also wears white gloves.
After looking into the Boundary, something happened to Carl's left eye, and he now covers it with a mask. His right eye now has a monocle covering it instead of his glasses.
More mature than his age would suggest, Carl can handle any difficulty that comes his way with skill and speed. Polite and friendly, he is always smiling — even in the heat of battle.
Headstrong and intelligent are two words that succinctly describe the bravado that Carl often shows. His behaviour is often courteous and gentlemanly to both friends and enemies alike, and he will often demonstrate his linguistic capabilities. That said, his manner belies that of a child who has lost his family, and he’ll often be driven to the very edges of his mental limits thanks to the cruel circumstances that plague his life. As a wielder of a Nox Nyctores, Carl has side effects that often come into play, such as an incredible and insatiable desire to attack others under the guise that his sister commanded him to attack. This mental instability clashes heavily with his otherwise sophisticated behaviour.
Being inside the Embryo changed Carl deeply. He became truly obsessed with saving Ada, and was ready to murder anyone in his way - something that his sister would do to stop, even if it was for her. Eventually, Carl had cut off ties to everyone, and now views them as objects, becoming the perfect heir to his father's legacy.
Powers and Techniques
Carl is a gifted wielder of the Deus Machina: Nirvana despite his young age and fragile appearance. The two make a perfect pair as Nirvana’s wide array of options are perfectly complimented by Carl’s different knights that he keeps with him to attack an opponent; as a testament to this, Carl’s strength is enough to even keep up with the likes of Izayoi. When fighting alongside his parents, Relius and Ignis, Carl and Nirvana are nigh unbeatable.
However, Carl is, as mentioned before, rather fragile, and can easily succumb to his wounds. His single-minded determination to acquire something can make him overlook crucial information at times. On top of this, Hakumen has suggested that Nirvana amplifies his bloodlust, making this crux additionally difficult to overcome. When desperate enough, Carl will even enlist the help of sketchy narcotics in order to temporarily amplify his strength, even if they have devastating side effects.
A young boy who is one of the highest-ranking Vigilantes.
Due to his talents, he was invited by the NOL to attend the Military Academy as an honor student. His aptitude for Ars Magus is unprecedented. Although he was in the academy while Noel and Jin were there, he eventually left.
His thought process is mature for his age, and he is able to swiftly and cleverly perform in almost any situation. The abandonment by his own kin results in distrust towards all adults, festering certain aggression within him. However, he maintains a graceful façade in front of his targets, never letting them see his true colors.
He fights alongside the automation, ‘Nirvana,’ and has a deep, abnormal affection for her. Perhaps because his sister Ada is in fact the framework upon which Nirvana is constructed.
Carl seeks the Azure Grimoire, believing it is the only way to save his sister Ada from her fate. He sets his sights on two targets: Ragna the Bloodedge and Kokonoe…and his journey takes him to Ikaruga.
Though full of hatred towards his father, Relius Clover, Carl lowers his blade with his father’s promise that he will one day reconstruct Ada.
