In the Wii game Super Smash Bros. Brawl, the Black Knight makes an appearance as a trophy. But, in his description, he was stated as the wielder of the sacred blade Ettard, instead of Alondite. However, this was a change made from the Japanese version to the English, on part of Intelligent System's translation team: the Black Knight's blade in the Japanese version was Ettard while Ike wielded Alondite. Also, his battle music, unchanged since Path of Radiance, was a possible music for the Castle Siege level, although the music was titled "Against the Dark Knight" instead of "Against the Black Knight" - although he is known as "The Dark Knight" in the Japanese version, probably just a localisation mistake - the same happened to Lyn in her trophy (they put her age as 15 - as it is the Japanese version, instead of writing 18 as she is in the localized version of Fire Emblem). He makes another appearance as a sticker.
One of Daein's Four Riders and wielder of the blessed sword Ettard. Once an apprentice to Ike's father, Greil, the two eventually duel, resulting in Greil's defeat. Thought to be dead after losing to Ike and the blessed sword Ragnell, the Black Knight survives and comes to the aid of Micaiah, the leader of the Dawn Brigade, a band of Daein freedom fighters.
It can be noted that Zelgius does not wield Alondite while wearing his General armor, most likely to hide his second identity as the Black Knight.
In Radiant Dawn, since the Black Knight is playable in some levels, you can raise his lance weapon level from S to SS.
In Radiant Dawn, if you use the Black Knight with a lance, you can notice that the lance is misplaced, going through his hand; this is most likely an oversight, due to the Black Knight having access to Alondite.
