Both this monster and "Chimeratech Overdragon" are based on the Chimaera, a mythical beast who had three heads; that of a dragon, lion, and goat. More recently, 'chimaera' refers to the idea of combining things that occur naturally, much like both monsters are fused from varying Machine-Type monsters.
This monster's body appears to be made of nine portals. Each portal seems to produce the head of a "Cyber Dragon", likely referencing the fact it gains 1000 ATK per monster during Fusion. Including the mouth, this would allow the dragon to have ten heads, likely referencing the number of monsters that can be on both sides of the field at once (until the introduction of Extra Monster Zones in Master Rules 4).
The maximum ATK this card can reach with its effect is 13000. This is achievable with an active "DNA Surgery" set to Machine and twelve monsters, including "Relinquished", or a similar monster, equipped with "Cyber Dragon".
This is the first Fusion Monster Special Summoned by Contact Fusion whose Fusion Materials do not have to originate from the side of the field of the player conducting the Contact Fusion.
