The Chaos Knights Knight Ruinator  is a prominent multi-option plastic centerpiece kit for Warhammer 40,000. Introduced alongside an updated Codex, this kit provides a heavy close-range fire support chassis designed to spearhead offensive lines and hunt down high-value targets. 
The box contains 207 plastic components and a Citadel 170mm x 109mm Oval Base. It includes a specialized upgrade frame featuring localized weapon options and a unique "ruined skull" faceplate, alongside a comprehensive Chaos Knights Transfer Sheet packed with 339 thematic waterslide decals. 
The kit can be assembled into one of four massive configurations.
Knight Ruinator: A short-range brawler armed with a massive Darkflame Lance (torrent flamer cannon), a devastating Fellbore siege drill, and a chassis-mounted Terrorpulse missile launcher.
Knight Abominant: A psychic-infused variant equipped with a Volkite Combustor, a Balemace tail, and a signature writhing Electroscurge tentacle claw.
Knight Rampager: A pure melee terror built for raw assault impact, armed with a Reaper Chainsword and a Warpstrike Claw.
Knight Desecrator: A dedicated armor-hunting platform housing a high-power Desecrator Laser Destructor alongside a choice of close-combat weapons.
 
On the tabletop, the Knight Ruinator is a durable 26-wound brawler that benefits from unique target-hunting dynamics:
Methodical Destruction: Allows the pilot to mark an enemy unit as its "victim" at the start of the battle, granting potent wound re-rolls until that specific target is ground into dust.
Anti-Armor Prowess: The Fellbore melee weapon strikes with high strength and features the Anti-Vehicle 2+ and Anti-Monster 2+ keywords, ensuring it wounds the toughest targets easily on a 2+ roll.
War Dog Synergy: Features a close-range aura that enhances nearby smaller War Dog squires, giving them increased armor penetration (+1 AP) when targeting the nearest foe.
