⎈The JOKER⎈’s Dlclaifsein cosmogony reveals that Leonardo LionHeart is a former scientist in the Mercphobia Alliance, who joined the Church of Necessary Evil. As his faith in God became greater than himself, he believed in the necessity of evil. This pushed him to join the church in order to expand his beliefs on those who also possessed great faith. Thanks to his knowledge, plus Christopher Sincere Pride's research about possibility, he was able to establish the Red Devil's Research Lab.

Powers and Abilities

⎈The JOKER⎈’s Dlclaifsein cosmogony reveals a more thorough explanation of his powers and abilities than what can be found here. Leonardo is a powerful enough fighter that he was shown to be able to easily fell 6.6 tredecillion Paracletes, without any theoretical measure of effort.

Big Bang Imitation: Leonardo has been shown to be able to release a power that was so immense, that it released energy similar to the explosion that gave birth to the universe; the Big Bang.

Never-ending World: Leonardo can encase himself and his target within the bounds of another universe. This world is housed with nothing but Suns. Every other material object in the infinite universe was a Sun. The universe itself is ever-accelerating and an absolutely infinite multiplicity. If this world is destroyed, annihilated, or erased, it will just re-spawn until Leonardo decides to stop it himself. The limits of this ability are unknown.

Ende des Himmels: This is an attack that shows the visual of Leonardo delivering an uppercut to his target that triggers a retrocausality effect that absorbs his target's information, and state of existence, erasing the target from existence.

Ende der Holle: This is an attack that shows the visual of Leonardo executing a devastating dropkick to his target, which triggers a retrocausality effect that erases the entire infinite Metaverse. The mere force of the dropkick erases all infinite connecting dimensions and timelines in an instant. This means narrative causality is unable to register this.

Lion Hart: This is an attack that shows the visual of Leonardo releasing a wave of energy so colossal that it shatters a Traeumende effortlessly. A Traeumende is formerly known as Cardinality of the Continuum, which has always canonically been beyond a Region on the 1st Floor. The amount of energy released from this attack surpasses any Name, Term, and Essence from outside of the Universe, outside of reality, and from the Divine Ground that gave birth to all phenomena, all possibilities, and the boundless Omniverse.

Enhanced Speed: 

• Leonardo on a scale that can be measured is able to execute a flurry of punches of an exact amount of 7.9 quindecillion punches, with each punch being shown to be thrown from every single angle, backed with an infinite amount of concentrated force. The infinite used here is bigger than any conceivable or inconceivable quantity, either finite or transfinite, larger than any set hierarchy and the paradoxical totality of all sets, and greater than the system Ω of all [ordinal] numbers which is an inconsistent, absolutely infinite multiplicity. .
• Leonardo is able to move before information, change, and any system of time could begin to advance. His agency is outside of Names, Terms, and Essence that can be linked to the pataphysical notion of presence and and the pataphysical notion of change.
• Leonardo operates at a level beyond the necessity of presence and "act" beyond the necessity of change. This means he operates beyond All, The All, and THE ALL.

Enhanced Strength: With the snap of his finger, he has been shown to be able to annihilate the entirety of the Universe. This is simply a mere flex with him using 0% quality of effort.

Enhanced Resistance: Leonardo has such a boundless resistance that his human "soul" and "mind" are unable to be affected by outside forces. Outside forces mean Realm Reborn Red and lower. Anything that isn't above Tier 7 (middle) is also considered outside forces.

Absolute Regeneration: Leonardo’s human essence was broken down into Vārvaḍavzūha. Existence and Narrative Causality could not process his restoration as he regenerated before Pataphysical "change" could be.

• When his life, dreams, mind, consciousness, soul, and essence as a human were erased, he simply regenerated before any infinite Hierarchy of Narratives of could register actuality and/or potentiality.

Self-Temporal Dimension: On an illusionary level, Leonardo exists within his own timeline. This means that he has his own personal time that he travels on, completely unaffected by any Metaphysical or Pataphysical logic of time. He is unable to be affected by temporal phenomena outside of his own barrier.

• On a higher level that is beyond Names, Terms, and Essence, Leonardo exists within his own grand-meta narrative, meaning he is unaffected by those that can utilize Realm Rebron Red.

Empty Presence: Leonardo has no conceptual aura. He doesn't exist in a sense where his intentions can be read. He is not within the universal time stream but within a completely different time stream of his own.

• Leonardo is beyond a transcendence that is beyond all concepts and boundaries and a constant ever-growing absolute boundlessness, where he exists outside of all of existence and nonexistence.

Transcendent Reactions: Leonardo is beyond "Pure Act" and "Divine Will" before that of an Omnipresent force. This means that something fully akin to a Deus is less than Leonardo.

Reality Manipulation: Leonardo was shown to poke the reality before him, shattering all of reality.

Telekinesis: Leonardo has shown that he can mentally throw the Sun at his opponent.
