Galaxy Convoy

The commander of Cybertron forces and bearer of the Matrix of Leadership during the events of Galaxy Force. Although stern and determined to stop Master Megatron at all cost, he cares deeply for his people and residents of other planets alike, not wanting to disturb their peace - he's also quite friendly with his subordinates, not minding their jokes and occasionally cracking a joke or two on his own. While initially not too keen on the idea of revealing Transformers' existence to residents of Earth, he changes his mind upon meeting Coby, Lori and Bud, seeing the value of cooperation and friendship with humans for himself.

He is capable of transforming into two distinct robot modes - a more casual, mouthplate-less form in which his alternate mode is a futuristic truck, and Super Mode, a more combat-oriented and heavily armored form, in which his alternate mode is a futuristic fire engine, capable of flight by extending its sides into wings. Upon combining with Ligerjack, he assumes the name of Liger Convoy (ライガーコンボイ), granting him a gigantic, clawed right arm, and upon combining with Sonic Bomber, he becomes Sonic Convoy (ソニックコンボイ), equipped with a jetpack and twin swords. He's also able to use Megalo Convoy's Megalo Ax.

In the US adaptation of Galaxy Force, Transformers: Cybertron, he is renamed to "Optimus Prime" and stated to be the same character as Convoy (Micron Densetsu)/Grand Convoy.
