Ace Lightning

Within the television series Ace Lightning, British teenager Mark Hollander discovers a hidden/seventh level of a fictional video game. A lightning bolt strikes the antenna on his roof, and through an electrical surge the game's characters come to life and occupy his town. Ace Lightning is presented as the game's titular playable superhero — a Lightning Knight from the Sixth Dimension whose in‑game objective (to traverse the Carnival of Doom and recover pieces of the Amulet of Zoar while battling Lord Fear) carries over into the real world. Ace subsequently 'hires' Mark as his sidekick to fulfil these game objectives in the human setting.

Ace Lightning is portrayed in the series as a computer‑animated/CGI superhero and the titular playable character from the fictional game Ace Lightning and the Carnival of Doom. Sources identify him as a 'Lightning Knight' from the Sixth Dimension and the show's titular character, but the provided materials do not give detailed physical measurements or a full costume description; he appears as an animated superhero figure interacting with live actors.

Described in the sources as a superheroic Lightning Knight and protagonist of the in‑game Carnival of Doom scenario, Ace's narrative functions include seeking Amulet of Zoar pieces, battling antagonists led by Lord Fear, and recruiting human allies (notably Mark Hollander) as sidekicks to complete game objectives in the real world. The series establishes game mechanics that transfer to the human setting: for example, connecting two pieces of the Amulet can summon new characters or weapons, and completing game objectives can return antagonists to the game world (Mark 'winning the game' returns many villains). The sources note strategic alliances in the narrative (Ace and Lord Fear jointly banish Kilobyte) but do not enumerate explicit physical powers such as flight or energy projection.
