The Octoloud is a large transporter Zoid employed by the Republican Army, and is one of the very few sea-based transporters. While other Zoids, such as the Whale King , are capable of submerging, no other transporters has been strictly an ocean-based carrier, making this Zoid somewhat unique. Like many other carriers in the Battle Card Game, Octoloud was originally a concept art in the Smack! Zoids series.
Compared to common Imperial transporter units, the Octoloud has a much higher Zoid capacity, with a large carrier section in the central body and if absolutely necessary, capable of carrying additional Zoids on all eight tentacles (although, that is probably not recommended). The only down side to this carrier is that its capacity is limited to small or medium sized Zoids. Luckily, this size limitation makes up the majority of aquatic Zoids on both sides of the war, which may show that the transporter is also an effective submergible war machine. It is noted to have a third of the armor durability as the Ultrasaurus.
Octoloud was seen in Volume 6 (Republican Army Faction) of the Zoids Battle Card Game. It did not feature any statistics (in terms of height and weight), and did not feature an official registration number (although the card is B-005 in its set)
