- This card, "Neurogos", and "Synaphysis" were the first Insect-Type Link Monsters.
- However, this card was revealed first.
- This is the first monster, and the first card overall, whose effect is dependent upon the player controlling 6 or more monsters, which only became possible with the introduction of the Extra Monster Zones and Link Monsters.
