In Getter Robo Daikessen, you receive the Shin Getter Dragon in the last stage in the game, stage 21. Here, Shin Getter Dragon was born when Saotome Lab used Getter Robo G as the battery for Getter Emperor. During the process, it mutates into a new form. This version of Dragon could not split into three but three pilots still could pilot the mecha. It incorparates some of Liger's & Poseidon's attacks like shooting a huge missile out of its navel and turning the right arm into a huge drill. The Getter Beam appears in the form of the mech summoning a large gun with a barrel that resembles the head of a Getter Robo. Its final attack is the Shin Shine Spark, which is initiated by Shin Getter Dragon summoning energy around its body. Compared to other models, it resembles a more traditional Getter robot compared to the more strongly changed counterparts.
The Shin Poseidon is a form also assumed by Shin Dragon. In Armageddon the colors on the head are reversed, but is arguably the form that is closest to the original Poseidon. The left hand is replaced with a wrecking ball while the right resembles a large baseball mitt that can form a large electric net. Its other weapon is essentially an enhanced form of Getter Cyclone performed with three fans instead of one.
