Angron (Warhammer 40k) powered by nothing but pure rage, the butcher's nail and warp power, he genuinely wants to mow down EVERYONE AND EVERYTHING in front of him, be it friends or foe

Zaraki Kenpachi (Bleach) shinigami who actively seeks other strong opponents so he can feel the thrill of fighting at full power

Lobo (DC Comic) space bounty hunter who famously wiped out his own race, he will stop at nothing, and I mean NOTHING

Ryōmen Sukuna (Jujutsu Kaisen) more curse than human at this point, this guy NEVER duck a fade. Even when getting jumped, he just made another binding vow and pulled new techniques out of his ass

Battle Beast (Invincible) space beast who's just like Kenpachi, hunt for a worthy opponent. Famously slicing off his own stomach to level the playing field when Thragg got injured by another monster

Rayquaza (Pokémon) some people named him the King Von of Pokémon for a reason, this space snake is known for sniping Deoxys at point blank range and mega evolving for the love of the game with sheer willpower alone

Madara Uchiha (Naruto) do I even need to introduce this guy?, fight the entire shinobi alliance alone, dropped 2 meteors, fight the 5 kage, slice 2 mountains, 1v9 the tailed beast, killing the MC

Yujiro Hanma (Baki) genuinely thinks anyone weaker than him is female, the first thing this guy does when he heard a resurrected 8 feet tall prehistoric man by the name of Pickle, he break into his enclosure and fistbump him

Barbatos Lupus Rex (Gundam: Iron Blooded Orphan) one of the most ferocious gundam of the series, when combined with Mikazuki Augus' bloodlust it can genuinely tank an orbital strike while fighting other gundam

[Loved Trope] when the character wants ALL THE SMOKE
