- The "Elemental HERO" designs were mostly based on American super heroes. This monster's design is based on DC comics hero Hawkman and/or the Marvel Comics hero Archangel
- It is also possible that this monster is based on the DC comics hero Nightwing due to almost identical masks and the flying/bird theme they both share, it can also be argued that Avian's presumed position as the leader of his group which consists of Burstinatrix, Bubbleman, Sparkman, and Clayman as seen in the artwork of "Fifth Hope", mirrors Nightwing's as the leader of the Teen Titans.
- The word "avian" is related to birds and flight, hence this monster's appearance and Attribute.
