- This card's name 'Laggia' comes from the dinosaur genus Unenlagia.
- This card's effect is similar to the effect of "Solemn Judgment", except that it can't negate Flip Summons and Counter Trap Cards.
- This is the first card to be able to detach all of its Xyz Materials at once.
- This is the first "Evolzar" monster; second being "Evolzar Dolkka" and the third being "Evolzar Solda".
- This card's title 'Evolzar' comes from the words "Evol" and "Czar", the latter being the Russian equivalent of a king. Hence, this card and the others "Evolzars" are the Kings of the "Evol" monsters.
- In the bottom-right corner of this card's artwork is what appears to be a depiction of human evolution.
